M.Sc. / An estimated 98% of the iron ore exploited in the world is used in the manufacture of pig iron and steel, which are non-substitutable backbones of modern society. The rapid increase of world steel production over the last few years, driven mainly by economic growth in China, have required an equal increase in iron ore production, from 876.8 Mt in 2006 to 948.1 Mt in 2007. The increased rate of exploitation of iron ores has resulted in a rapid depletion of known high-grade iron ore deposits. This, in turn, has led to a dramatic increase of prices, especially for highly thought-after high-grade lumpy iron ores from BIF-hosted deposits. In the absence of any major new discoveries of high-grade iron ore deposits, mining companies have turned to lower-grade materials to assess their beneficiation potential to expand their production base and beneficiation capacity, in order to satisfy future demand. Within this existing framework, this research project was initiated to assess the beneficiation potential of low-grade lumpy stockpiles and high-grade iron ore fines at Beeshoek Iron Ore Mine, owned by Assmang Ltd. The mine is located 7 km West of Postmasburg, in the Northern Cape Province of South-Africa, and processes currently 5.60 million tons of uncontaminated run-of-mine ore per annum. Crushing, washing, classification and jigging are used to produce 2.12 million tons of (37.8% of ROM) of lumpy iron ore product. The balance (3.48 million tons) is currently not used, but is stockpiled or discarded. This includes 0.90 million tons (16.2% of ROM) of ore-grade fines, 0.86 million tons (15% of ROM) of tailings sludge and 1.74 million tons (31% of ROM) of lumpy low grade material. Both ore-grade fines and low-grade lumpy material are discarded separately; they are currently considered as waste. The low-grade lumpy is stockpiled while the fines are used to fill-in mined-out open pits. The evaluation of the beneficiation potential of these two material streams is the main goal of this study. Representative samples were collected from ore-grade fines and the current stockpile for low-grade lumpy material. Hand sorting and lithological categorization of the lumpy material facilitated petrographic and mineralogical studies using light and scanning electron microscopy, as well as X-ray powder diffraction studies. Major and trace element geochemistry were determined using X-ray fluorescence spectrometry and titrimetry (to accurately determine the concentration of iron). Whole rock densities were determined for all lithotypes recognized in the low-grade lumpy material. The grain size distribution was determined for the lumpy materials by actual measurement of the diameter of a representative number of particles, and for fines by sieve analysis. Fines beneficiation tests were conducted using spiral separation and simple classification tests. Washing was used as additional beneficiation method on the fines.

M.A. / With this research, an Environmental Centre for the Northern Cape Province is suggested at Upington as an environmental management initiative. Environmental management aims to create an awareness and a concern for the environment and all its facets. In this way, knowledge, skills, attitudes, motivation and commitment are striven for, so that the environment and its related problems can be identified and solved by the community. Formal teaching cannot do this task by itself. An additional source is suggested. An Environmental Centre can benefit the community if it creates an awareness of the various elements of the environment, their interdependency and the necessity of a healthy environment for the survival of man. It can motivate the community to accept responsibility for the environment, provide the knowlegde and values so that solutions can be found for environmental problems. Upington in the Northern Cape Province has several unique qualities which can justify an Environmental Centre: • an unique climate with many human activities, • the availability of the Orange River's water, • its population composition, • Various economic activities(intensive/extensive farming) • a growing tourist sector, and • a very well developed infrastructure. A questionnaire was used to compile a residents profile to test the Environmental Centre initiative. Residents acknowledged the existence of environmental problems and that it must be addressed. An Environmental Centre with a well developed, co-ordinated and integrated environmental management plan, can be a solution. The way man sees his environment, indicates how he will utilise his environment. Knowledge and education about the environment can lead to citizens that know, understand and protect their environment against every form of deterioration. Environmental adulthood can thus be achieved.

The rock engraving site of Driekopseiland, west of Kimberley in the Northern Cape is distinctively situated on glaciated basement rock in the bed of the Riet River, and has a wealth of over 3500 engravings, preponderantly geometric images. Most other sites in the region have greater proportions of, or are dominated by, animal imagery. In early interpretations, it was often considered that ethnicity was the principal factor in this variabilty. From the 1960s the focus shifted more to establishing a quantative definition of the site, and an emperical understanding of it within the emerging cultural and environmental history of the region.

M.A. / Natural phenomenon such as droughts have a definite influence on the availability of water sources, soil profiles and vegetation of an area. Man should adapt his activities, such as farming, to the current climatic elements of the area to ensure his existence. Intermittent rainfall and the occurrence of droughts caused symptoms such as desertification. Desertification has reached an alarming level in South Africa, so much so that the level of environmental degradation in the Northern Cape Province caused great distress. This caused many questions into the activities of man in this area. The problem that arose out of this is, does man cause a negative impact on the environment with his farming activities? The specific area of concern is the Southern Kalahari-dunefield, with its unique ecosystems. This area can be described as an semi-arid desert with very sensitive ecosystems. Any form of interference can cause a long term ecological disruption. This area contains several hidden resources which are optimally used by man and animals to live a decent life. The development of these resources (e.g. water) over the past decades lead to the advantage for all concerned. However, the real danger of over-utilisation and exploitation do exist. Questionnaires were used to gather data concerning stock farming activities in this area. Information was obtained regarding water resources, vegetation cover, endemic animals, type of farming, ground cover and other economic activities such as tourism. Man is an additional determinant who causes an impact on his environment in the Southern Kalahari-dunefield. Although a change can be observed over the past decades in the activities of man to enhance sustainable development, continuous strive to the implementation of new methods to preserve resources in the long term, must be encouraged.

M.Phil. / The problem that exists in the developing areas of the Northern Cape area of Eskom (and also in all other developing areas in South Africa), is to make the correct decisions in terms of electrification, marketing and sales of electricity and electrical appliances when electrifying these areas. This study investigates this problem. The results from field work before and after electrification and recommendations form the main part of the study. The main methods followed for this study were as follows: Previous pre-electrification studies over a period of roughly six years in 82 developing areas were aggregated into 33 tables with maximums, minimums and averages calculated, including compiling 52 graphs. This process took the best part of one year. This gives an in-depth combined view of energy - and socioeconomic aspects particular to the Northern Cape. A needs analysis was also done amongst role players inside and outside Eskom, inter alia the management of Eskom, municipalities, Rand Afrikaans University, electrical contractors and district councils. The most important needs were investigated during field work done for this study in 1994. Data processing in dBase and Microsoft Excel and statistical analysis in Statgraphics was done, and the findings were taken up in four internal before/after publications during 1995 and 1996 and finally, in this study. It provides a clearer insight into electrification -, socio economic and health aspects in the developing areas of Northern Cape before and after electrification. Electrification in developing areas in Angola, Zambia and Zimbabwe is uneconomical and in many cases has just about come to a standstill. Electrification in Namibia and Botswana is progressing slowly, at a cautious economic pace. Amongst the most important findings (in another 29 tables and another 58 graphs) for the Northern Cape area of Eskom are: The number of prepaid customers in the developing areas grew from less than 100 in 1989 to more than 38 000 in 1996, an increase of more than 20 000%. At this stage these customers of Eskom consume 4.148 GWh of electricity p.m., the equivalent of about 4 148 big households, each consuming 1 000 kWh (units) of electricity. This translates to only 109.16 kWh (Eskom ±70 kWh nationally)per customer p.m., which is not even nearly economical to Eskom. It must be remembered that it took 20 years in Ireland for electrification programmes to become economically viable. The target of Eskom in South Africa vary from 350 kWh to 572 kWh p.m., the latter which can only be achieved by "second phase" electricity consumption, i.e. by using heavy appliances such as geysers as well. When the developing areas have been fully electrified, total electricity demand in South Africa could increase by 7.4%, which could cause the building of another 1.26 big power stations. After electrification, there was a statistically significant reduction in the monthly average spending on wood and coal in the developing areas of Northern Cape. The electrical appliances mostly in use (after electrification) are irons, kettles and TV's. After electrification there was a statistically significant increase in the percentage of the maximum average "marketing potential" of appliances. The electrical appliances that most residents still want to buy after electrification, are washing machines, fridges and geysers. After electrification, only 68.63% of kettles are electrical types (on average). Nearly all electrical appliances are used during the peak hours of Eskom. The maximum amount that residents are prepared to spend on electricity, is R75.89 p.m., compared to R53.64 p.m. before electrification. The recalculated total average spending on energy (excluding petrol and diesel) is R91.72 per month before electrification and R121.21 p.m. after electrification. The average level of education is between standard 5 and 6 compared to between standard 3 and 4 before electrification (this is also statistically significant). The average income of households is R943.89 p.m.,compared to R507.59 p.m. before electrification. The average number of people per household is the following (pre-electrification figures in brackets): men 1.05 (0.96), women 1.21 (1.17) and children 3.26 (2.98). The total number of people per household is 5.51 (5.11). Most residents are very satisfied with health services in their areas. The biggest group (on average 95.30%) in the electrified developing areas of Northern Cape make use of modern medicine. The next biggest group (on average 4.7%) make use of modern medicine and traditional healers.

Magister Philosophiae (Land and Agrarian Studies) - MPhil(LAS) / Municipal commonage has the potential to make a major contribution to land redistribution in South Africa. During the Apartheid era, land under the control of local government was leased out to commercial farmers at commercial rates, which ensured an important source of income for municipalities. Post-1994, municipalities have been tasked by the Department of Land Affairs with making land available to the previously disadvantaged and thus managing and administering the commonage for purposes of poverty alleviation.

Empirical evidence has shown that goats are of significance in marginalised, poor, and rural economies and this information has been well documented in scholarly research. Despite its importance and potential contribution, goat farming remains underutilised and undeveloped in the rural economy - particularly in South Africa. Developmental intervention has focused on improving productivity with minimal effort aimed at the integration of key role players in the value chain, and even less emphasis on improving farmers' attitudes. The largest goat population in South Africa is found in the Northern Cape where there is great potential to be realised for goat farming. The main objective of this study was to identify supply side (production) factors constraining subsistence goat production in South Africa, with the view of identifying key actors to establish an innovation platform through vertical integration. By transforming the subsistence farming orientation of goat farmers into a commercial (market) orientation, the welfare of communities can be improved through the commercialisation of smallscale goat farmers. Studies highlight the need to enhance goat production beyond subsistence goat rearing and towards commercialisation through access to markets, veterinary services, credit facilities, and government support. Furthermore, a focus on market development, value chain integration and innovation platforms can improve the efficiency of the goat farming sector. This study contributes to the existing body of knowledge on goat farming in South Africa and offers an innovation platform to foster partnerships among the actors along the value chain, creating an enabling environment for the easy flow of market information and infrastructure development. A praxis model is incorporated into this research. This takes the form of a business model and is provided in Appendix B as a practical way of applying the knowledge gathered in this research.

Masters of Commerce / In South Africa land dispossession and land appropriation were legally instituted with the promulgation of the 1913 and 1936 Land Acts and the 1950 Group Areas Act that saw the forced removal of the majority of Black South Africans from their homes and livelihoods. This policy of racial segregation left in its wake countless examples of families and entire communities being uprooted and forced to eke out an existence on land that often had no or little potential for development. The Tswana people who resided on the farm Schmidtsdrift in the Northern Cape is an example of a community that was forced to relocate to a barren piece of land called Kuruman about 140km from Schmidtsdrift. In 1994 with South Africa’s first democratic elections, a number of policy changes were affected that sought to undo the injustice of the past. The Land reform programme initiated by the government provided the Tswana people an opportunity to reclaim their land under the Land Restitiition Act o2 of 1994. The new policy changes were certainly far reaching in addressing the legacy of landlessness but it became clear four years after the initiation of the programme that serious delays with regard to the finalisation of the claims were being experienced. By 1998 only 9 claims of the 26 000 claims lodged with the Commission on the Restitution of Land Claims were finalised. One of the claims that were still awaiting finalisation at this stage was the Schmidtsdrift claim lodged by the Tswana community in November 1996. It is within this landscape of challenges faced by the land restitution process that this research report examined the obstacles, specifically: from 1996 to 1998, experienced by the Schmidtsdrift Restitution Case with regard to the settlement of their claim.

Thesis (MScAgric (Soil Science))--University of Stellenbosch, 2007. / South Africa is a water scarce country and in certain regions the quantity of surface water is insufficient to provide communities with their domestic water needs. In many arid areas groundwater is often the sole source of water. This total dependence means that groundwater quality is of paramount importance. A high nitrate concentration in groundwater is a common cause of water being declared unfit for use and denitrification has been proposed as a potential remedy. In groundwater of the Marydale district in the Northern Cape Province, nitrate levels are high enough to be of concern for domestic and livestock consumption. A review of the literature indicates that bacterial denitrification of groundwater can be achieved in situ by using a suitable energy substrate. The technology has been tested elsewhere in the world but more certainty is needed on whether it is a feasible option for local groundwater remediation using local, cost-effective energy substrates and exploiting bacterial populations present naturally in the regolith. The objective of this study was to perform denitrification experiments by laboratory incubation using soil and groundwater samples collected in Marydale in order to determine; 1) The effectiveness of different carbon sources; 2) The effect of using soil sampled at different depths; 3) The effect of C:N ratio of the carbon substrate; and 4) The quality of resultant water. Various experiments were set up using 10 g soil and 40 mL groundwater with different concentrations of carbon sources (sawdust, glucose, maize meal and methanol). All experiments were done under a nitrogen atmosphere to exclude oxygen and temperature was kept constant at 23 °C. Indicator parameters were selected based on literature review, and major cations and anions and some metals were analysed for initially and at selected times during each experiment to evaluate whether major ion chemistry was changing over time. Parameters analysed in supernatant solutions after varying periods of time to indicate progress of denitrification and reduction included nitrate, nitrite, sulfate, alkalinity, chloride, acetate, basic cations, ammonium, pH, electrical conductivity, dissolved organic carbon, heteThe Marydale groundwater in some boreholes is of predominantly NaCl type and the nitrate concentration of 19-32 mg/L as N exceeds ideal limits for drinking water of 6mg/L as N . Two soil materials were sampled at different depths from a red sand overlying calcrete (Plooysburg form, Family Py1000). The incubation experiments showed denitrification was complete within a period of between 1 and 6 weeks depending on the carbon substrate and C:N used. Higher rates of nitrate removal were achieved where greater C:N was used. Readily degradable carbon substrates e.g. glucose showed rapid denitrification, while sawdust, a slowly degradable substrate, effected slower denitrification, hence it was concluded that intermediately degradable carbon substrates e.g. wheat straw may prove more suitable. Use of shallower soil material containing initially higher nitrate levels resulted in better denitrification rates, however, both soil materials effected denitrification.. Heterotrophic plate counts increased with time, this presence and growth of heterotrophic bacteria confirmed that conditions were optimum for growth and denitrification and that inoculation with bacteria is not a requirement for in situ denitrification. Dissolved organic carbon (DOC) concentration could be directly correlated to the initial input of carbon substrate as soil and groundwater lacked organic material. Results showed that reaction products such as acetate and nitrite, and basic cation concentrations were elevated in the supernatant solution in preliminary experiments. This was interpreted to be attributed to incomplete oxidation of organic material and excess soluble and available carbon for reaction. Cation concentrations were interpreted to have resulted from a decrease in pH brought on by organic acids produced during denitrification. The method used showed specificity, as the only parameters affected by the denitrification experiment were DOC, alkalinity, nitrite, nitrate, and the heterotrophic plate count. The DOC and HPC did not comply with acceptable levels for drinking water. Removal of HPC by boiling or chlorinating is required to ensure that the resultant water composition is of potable quality. For further research with slowly degradable carbon sources it is recommended that a C:N ratio of more than 12 should be employed, and monitoring should focus on soluble carbon nitrate, nitrite, and heterotrophic plate count. The study confirmed that denitrification of this groundwater with a range of carbon sources is possible within a short period of anaerobic contact with local soil material. With sufficient knowledge of the characteristics of the soil and groundwater in the area, establishment of a working in situ denitrification plant is probably feasible.

<p>Spousal communication on issues related to family planning and reproductive health is important in influencing fertility limiting behaviour. In South Africa, studies analyzing the relationship between spousal communication and family planning behaviour are virtually nonexistant. Understanding this relationship is critical for less developed countries where fertility remains at substantially high levels. In most countries, the isolation of men's participation in family planning issues is acknowledged as one of the major causes of poor performance of most family planning programs. In addition, lack of spousal communication about family planning is identified as one of the reasons for low levels of contraceptive use among women. The main objective of this study was to assess spousal communication on contraceptive use and family planning behaviour in three distinct areas in the Richtersveld (Northern Cape) area.</p>
