The UG3 at Modikwa Platinum Mine occurs as a platiniferous, planar chromitite seam. It is stratigraphically located in the Upper Critical Zone of the Eastern Bushveld Complex. Field work study comprise of underground mapping, sampling, surface mapping, borehole core logging, microprobing and microscopic investigations carried out at the Rhodes University. The UG3 at the Modikwa Platinum Mine is about 22cm thick chromitite seam underlain by a white fine grained anorthosite and overlain by a brown medium grained feldspathic pyroxenite. It is an incomplete cyclic unit consisting of chromite and feldspathic pyroxenite. The UG3 reef at the Modikwa Platinum Mine lease area represents a Platinum Group Metal resource of 300 million tons of ore at an in situ grade of 2.5g/t. Under the current market conditions the UG3 reef remains unprofitable to mine in an underground operation due to the operational cost involved. However, it has been illustrated that the UG3 chromitite seam can increase profit margins in an open pit operation provided it is mined together with the economic UG2 chromitite seam. The extraction of the UG3 as ore in the four Modikwa UG2 open pits would result in a combined operating cash profit of R330 million. The UG3 chromitite seam is platiniferous. The platinum-group minerals (PGM) range in size from less than 10μm to about 70μm. The PGMs are associated with sulphides and are both located in the interstitial silicates and are concentrated in the chromitite seam. The PGMs show a strong preference to contact boundaries of the silicate grains, the chromite grains and the sulphide phases. In some instances, they are enclosed within the chromite grains in association with sulphides. The general sulphide assemblage comprises pentlandite and chalcopyrite whereas, the PGMs assemblage comprises cooperite, ferroplatinum, laurite, FeRhS and PtRhS.

Resource control as a form of community participation in the mineral economy has gained much recognition. One prevailing argument is that direct control of natural resources by local communities is an important precondition for equitable utilisation of the natural resource wealth, peaceful co-existence between mining corporations and indigenous communities, and congenial relations between local communities and the state. Studies have also shown that the absence of direct community control of mineral wealth remains a major factor in the communal resistance and socio-political conflict witnessed in the natural resource-endowed regions of countries such as Nigeria, Ecuador, Sierra Leone and the Democratic Republic of the Congo. However, little is known about mineral resource control at the community level. Does community control necessarily translate to equity? How does local involvement in the mobilisation of mining royalties benefit different segments of the community? Indeed, how do different segments of the community “control” the wealth? What is the specific model adopted to engender broad-based community participation in the utilisation of mineral wealth – and does it matter? These theoretical and practical questions were the impetus for undertaking this study in the Royal Bafokeng and Bakgatla Ba Kgafela – two platinum-rich ‘traditional’ communities in South Africa’s North West Province that have significant control over platinum resources in their territories. Utilising ethnographic data collected in the two study communities in 2008 and 2009, the thesis examines the character of community participation in platinum wealth utilisation; specifically, the conditions under which community participation promotes or hinders sustainable community development. The analysis uses a “three-dimensional participation ladder” conceptual scheme, based in part on Sherry Arnstein’s (1969) “ladder of citizen participation” and subsequent typologies of participation. Among the key findings of the thesis are that despite observed benefits, the interface of resource wealth and community development is fraught with tokenistic participation, elite-targeted grassroots anger, and local tensions – all linked to the contradictory nature of participation. The thesis further reveals that in some instances the challenge of platinum wealth-engendered community development tends to undermine existing customary and democratic spaces for participation, and that this is exacerbated by community-level issues such as poverty and inequality. The findings of the study compel a shift of analytical focus from conflict as an epiphenomenon of collective community exclusion and deprivation (as in the case of many natural-rich countries in Sub-Saharan Africa and elsewhere), to conflict as also resulting from collective community inclusion (in natural resource utilisation). At the policy level, the study generates insights that will, hopefully, assist mineral resource-endowed countries, such as South Africa, in dealing with the challenge of developing appropriate policy frameworks for regulating business and social partnerships between local communities and mining corporations, and within resource-rich communities themselves.

Thesis (M.Sc. (Geology)) -- University of Limpopo, 2022 / The Two Rivers Platinum Mine (TRP) located in the Eastern Bushveld Igneous Complex is currently exploiting platinum-group elements (PGE) in the Upper Group 2 chromitite (UG2) Reef at the Dwarsrivier Farm. TRP has acquired a new prospect (at the Buffelshoek Farm) and is currently planning to mine the UG2 Reef and potentially also the Merensky Reef (MR). Three drill-cores which intersected the UG2 Reef and MR at the Buffelshoek Farm made available by TRP were sampled for mineralogical studies using complementary techniques including reflected light microscopy, mineral liberation analyser and electron microprobe. The platinum group minerals (PGM) which host the PGE exhibit variability in their flotation rates and consequently variable PGE recoveries that is mostly attributed to the not so well understood PGM distributions and characteristics. The purpose of the study was to investigate the PGE process mineralogical characteristics such as the PGM phases, their modal abundances and mineral associations, as well as the grain size distributions within the UG2 Reef and MR at the Buffelshoek Farm. The observed PGM phases are broadly grouped into PGE sulphides, PGE arsenides, PGE bismuth-tellurides, PGE antimonides and PGE alloys. The PGM phases are largely dominated by PGE-sulphides (average of 80%) in the UG2 Reef and PGE-arsenides (average of 39%) in the MR. Although the UG2 Reef and MR are mineralogically different, the PGM observed are similar in composition, but vary in their proportions. The PGM are mostly associated with base metal sulphides typically, pentlandite in the UG2 Reef and silicates, which are dominated by amphiboles in the MR. The PGM grain sizes generally range between 2 and 22 microns in the UG2 Reef and range between 2 and 32 microns in the MR. The concentrations of platinum are the highest in both the UG2 Reef and MR, and with the platinum largely deported in PGE-sulphides (about 69 - 84.9%) in the UG2 Reef and PGE-arsenides in the MR. Palladium is mostly deported in the PGE sulphides (about 52.3 - 69.2%) in the UG2 Reef and mostly deported in PGE antimonides (about 43%) and PGE bismuth-tellurides (about 37%) in the MR. Rhodium (Rh) is entirely deported in the PGE sulphides in the UG2 Reef and deported in PGE sulphides (about 86.5%) and PGE bismuth-tellurides (about 13.5%) in the MR. Expected recoveries of PGM ranges from 76 to 89% for PGE sulphides and arsenides in the UG2 Reef and 61.3% in the MR, which is considered good. PGE bismuth-tellurides, PGE antimonides and PGE alloys are expected to be variably to poorly recovered, requiring suitable reagents to be well recovered both in the UG2 Reef and MR. / Faculty of Science and Agriculture Research Division Geological Society of South Africa North West University's School of Geo- and Spatial Science

This study sought to determine the impact of a training and development (T&D) programme on the perceived performance of human resource assistants at a platinum mine in South Africa according to the following four performance dimensions: (i) personal (ii) customer; (iii) internal business; and (iv) learning and growth. A non-experimental design was used for this study, which was predominately quantitative in nature. Data was collected using a structured, self-administered questionnaire, which consisted of closed-ended questions. Based on the results obtained in this study, it was apparent that the T&D programme contributed significantly to an increase in the performance of employees. However, there are certain areas that can be improved in order to maximise and optimise the learning of employees. Recommendations were made regarding areas for improvement and possible future research. / Human Resource Management / M. Tech. (Human Resources Development)

This study investigates the role that African traditional beliefs and practices play in defining psychological problems, determines how these beliefs and practices manifest in a counselling relationship and explores how Western based forms of counselling manage these manifestations in counselling. This investigation is in the context of the on-going debate on the relevance of Western Psychological counselling in South Africa and the rest of Africa, including my experience during my internship to register as a Counsellor. It explores the impact of conducting counselling with clients whose worldviews are different from those of the counsellor and focuses on the impact of the client’s worldviews on psychological well-being, psychological ill health and the resolution of psychological problems. Psychological well-being, ill health and counselling were discussed from a Western perspective. The study found that the client participants defined their psychological problems in terms of their African traditional beliefs and practices. They communicated their presenting psychological problems in ways that created possibility of miscommunication between themselves and their counsellors, for example by using figurative language. There was also a clear distinction between how psychological problems are managed from an African traditional perspective (ritualistic) and a Western perspective (talking therapy). The study recommended the creation of specific departments in Universities to embark on research aimed at establishing foundational structures on which to build an African Indigenous Psychology as an alternative to Western Psychology. More comprehensive research on African people’s attitudes is, suggested, on what traditional Africans think of psychological counselling. Another recommendation accruing from the limitation on sampling in this study is that future studies should be conducted with larger and more diverse samples; moreover, data should be gathered on a wider variety of demographics and cultural belief systems and practices. To counter prejudice and ignorance, the counsellor ‘to be’ should study African culture and customs during their BA Honours studies. On-going training and workshops on cross-cultural issues from various cultures should be part of the counselling profession. More emphasis should be placed on prevention and therefore more mental health clinics in the rural areas need to be opened and general education on psychological issues and cultural integration be initiated. / Psychology / M.A. (Psychology)

The researcher selected a quantitative cross-sectional design to test the concurrent validity of learning potential and psychomotor ability by evaluating the relationships between mining machine operators’ learning potential and psychomotor ability as well as their work safety behaviour. Work safety behaviour was considered indicative of their capability to operate a moving machine. The utilization of measuring instruments capable of measuring their learning potential and psychomotor ability and measuring safety behaviour by means of their safety score cards provided the required measurement data. The study involved a quantitative investigation into the relationship between learning potential and psychomotor ability as independent variables and safety behaviour as dependent variable. De Vos, Strydom, Fouche and Delport (2002, p.79) defined quantitative research as “based on positivism, which takes scientific explanation to be nomothetic. Its main aims are to measure the social world objectively, to test hypotheses and to predict and explain human behaviour. A quantitative study may therefore be defined as an inquiry into social or human problems based on testing a theory composed of variables, measured with numbers and analysed with statistical procedures in order to determine whether the predictive generalization of the theory holds true.” The aim of the study was to determine the learning potential and psychomotor ability of mining machine operators as well as compare the following sub-groups (based on the biographical variables): age, years’ experience, educational level and gender. The respondents’ work safety behaviour was measured and the relationship between the two measures of the independent variables (learning potential and psychomotor ability) and work safety behaviour determined. / Industrial & Organisational Psychology / (M.Comm.

ESKOM is moving towards a price structure for electricity which reflects, as far as possible, the real cost of generation. It is called real time pricing (RTP). ESKOM developed this cost structure to coax customers to use more electricity in off-peak periods (low cost of generation) and less electricity in peak periods (high cost of generation). However, many industries do not effectively use these price offerings from ESKOM to the detriment of themselves and ESKOM. In previous research improvements to this situation for the South African mining industry were investigated. ESKOM funded research to find the potential for load shifting on mines using RTP. The RTP investigation focused on the supply side management (SSM) in the mining context of underground services on gold and platinum mines. Elements investigated included the ventilation, cooling and pumping (VCP) systems. (Except for pumps, these plants are generally installed aboveground.) Previous research showed a national RTP and SSM potential to shift 500 MW of electrical load for a period of 5 hours. Through the previous research it became clear that the mines were previously able to react partially to the price signals. However, it was proved by the research that the full load shift potential can only be realised through the use of integrated dynamic simulation and optimisation. An even higher potential exists for load shift and electricity efficiency through demand side management (DSM) on the underground services. Therefore, if underground DSM strategies are combined with SSM strategies, a further and much bigger potential can be exploited to the benefit of ESKOM and the mines. Due to these factors this study was undertaken. Three case study mines were identified for this study. They are Kopanang and Target, both gold mines, and Amandelbult, a platinum mine. The DSM potential on each of these mines was calculated using simulation, calibration, verification and optimisation. These results were presented to mine management to negotiate the implementation of the proposed strategies on one of the mines. Kopanang's management agreed to the implementation of these strategies for a trial period of 3 months after which the success would be evaluated. The results of the implementation, together with the case study results, were used to calculate the national DSM potential in the mining sector through extrapolation. The DSM potential amounts to 650 MW of load per day as well as 5% on electricity consumption. This amounts to a potential saving of R72.1 million per year using current tariffs. This means that ESKOM can save about R5000 million on the building of a new power station to supply the equivalent load to the DSM potential. Now that the national impact has been calculated and discussed, all these findings must be used to motivate the implementation of these strategies throughout the mining sector. A similar project can be undertaken to look at possible DSM strategies in the industrial sector. This might prove to be more difficult as the electricity intensive systems are mostly all linked to the final production. In the mind of management this out-weighs the possible cost savings that can be achieved. ESKOM and the NER will have to rethink their strategy. Through DSM and load shifting actions alone the pending electricity crisis will not be averted. The current tariff structures should be amended to not only reflect the true cost of electricity but also provide incentive for DSM and load shifting. Another problem that must be addressed to achieve the DSM targets set for 2007 is the time that it takes to complete the study as well as the implementation time. Software can easily be created to help in the speeding up of the case study itself, as the process and steps followed, as well as models used, are very generic (at least in the gold and platinum mining sector). / Thesis (Ph.D. (Mechanical Engineering))--North-West University, Potchefstroom Campus, 2004.

M.Com. (Leadership in Performance and Change) / In August 2012 the South African mining industry was the focus of attention due to an illegal strike at Lonmin Platinum mine that resulted in the police shooting striking employees on 16 August 2012. Thirty-four employees lost their lives on that day. An additional ten people died in violent protests in the build-up to the main shooting incident. This strike period has become widely known as ‘Marikana’. This historical incident illustrates how a single incident within an organisation can have an impact at various levels and affect multiple stakeholders. The main objective of this study was to identify the effect that the Marikana mining incident had on Lonmin (the organisation) and its main stakeholders as well as to identify the effect the stakeholders and Lonmin had on each other. In order to reach these objectives an historical timeline of the sequence of events surrounding the Marikana incident was constructed. The main stakeholders involved in the Marikana incident were then identified, and the relationships and the relative strengths between these stakeholders were mapped. The methodology used in the study was Quantitative Narrative Analysis (QNA) as applied by Franzosi (2010). In particular, the content from English newspaper articles sourced from South Africa and England relating to the Marikana mining incident for the period 1 to 24 August 2012 were reviewed, coded and analysed. All relevant data from the articles were recorded in a manual database, coded according to the semantic triplet of ‘actors’, ‘actions’ and ‘subjects’ (S-V-O) (Franzosi, 1989) and analysed based on QNA principles (Franzosi, 2010). First, a sequence analysis was conducted, identifying the roles (consequences) that the respective actors (stakeholders and subgroupings of stakeholders) enacted as well as the order in which they unfolded. The analysis was used to produce a series of network graphs to visually depict the sequence of events and the respective effects of the sequencing of these events. These graphs take the form of stake maps and visually tell the story of how events unfolded and the effects of these events on all the actors involved ...
