The impact of the gold mining industry on the water quality of the Kromdraai catchment

Malan, Joël D. 11 June 2014 (has links)
M.Sc. (Geography) / One of the main objectives of the National Water Act (Act 36 of 1998) is the protection of natural resources (water resources) against pollution and misuse. These resources must be protected for the sustainable use by future and present generations. The study area consisted of the Kromdraai Catchment which included the Upper Wonderfonteinspruit, Lower Wonderfonteinspruit, Loopspruit and the Mooi River. This area is known for the amount of gold mining activities which may have a negative influence on the environment and especially on water. The aim of this study is to determine the impact of the gold mining industry may have on the water quality of the Kromdraai Catchment. Huge volumes of water quality data were collected from certain major monitoring stations throughout the Kromdraai catchment. A good indicator of pollution in a water sample is the electrical conductivity (Ee) of the sample. EC values were used to determine the pollution in each of the water samples because it saves time and costs. Pollution trends were established and conclusions were drawn to determine the impact of the gold mines on the water quality. A clear impact of a tailings dam on the water quality of the Turffontein Oog was established by the sharp increase in the EC values since the Doornfontein Gold Mine started depositing huge volumes of slime on the no. 3 tailing dam. The EC values of the Turffontein Oog have started to decline when the depositing of the slime was ceased. The conclusion of the study is that the gold mining industry has a definite negative impact on the water quality of the water resources in the Kromdraai catchment. The only effective way to mitigate and, manage these negative impacts, is through integrated environmental management. The sharing of data by all interested and affected parties is of critical importance, since most neighbouring goldmines are directly impacting on each other through the pumping and discharging of huge volumes of mine water. Catchment forums were established for the integrated environmental management of the Kromdraai catchment by all interested and affected parties. These forums have become important bodies representing stakeholders in the establishment of catchment management authority (CMA) that Will be established in the Upper Vaal Water Management Area.

Exploring ethical leadership and its association with sustainable economic performance within the gold mining industry

Nkosi, Nhlanhla Terance Mashobane January 2014 (has links)
The concept of ethical leadership has been intrinsically evident for over a century, but studies have only recently been documented that have attempted to observe and analyse the phenomenon. The concept has become more popular in the information age as companies start to employ additional knowledge workers who search for enhanced meaning in their respective occupations. The gold mining industry in Africa has improved substantially as conflicts have subsided slightly. As such, industry leaders need demonstrate better skills of engagement when managing legacy issues. While the shareholders’ interest remain high on leaders’ radar, leaders need effectively manage operations to address issues that might not be immediately evident in balance sheet, but that nonetheless have an effect on economic sustainability of the gold mining entities. Given that the concept of ethical leadership is known, there are still scandals that have recently been documented that involve leaders who have made decisions that led to demise of entities for which they were responsible. The purpose of this research was to explore ethical leadership and its association with sustainable economic performance within gold mining industries. The study aimed to analyse companies that have an African footprint, while originating from South Africa. A qualitative research method was employed following a phenomological approach to obtain insights of how African leaders have operated gold mines in Africa and have managed operations that performed very well. The aim was to crystallise and distil the findings for the use by future leaders so that they could avoid future scandals and not destroy shareholder value and disappoint stakeholders. The personal and leadership traits of ethical leaders were reviewed with the aim of determining the mental development that would be required, as well as which aspects would require consideration when determining the effects on economic sustainability. The African leaders interviewed were familiar with the concept of ethical leadership, economic sustainability and implicitly understood the association of ethical leadership with economic sustainability. The concept of ethical leadership generated two new terms, as described by the interviewees that could be infused to the definition to cater for an African context. The concept of “Ubuntu” and “displaying appropriate conduct” were the two terms that were derived from the leaders. The concept of greed was identified as a strong impediment towards economic sustainability. The gap of iii displaying that ethical leadership has a favourable outcome towards economic sustainability was demonstrated. By attempting to close this gap, it could help curb unemployment rates, as decisions would be made differently. From the propositions made, which were all proven successfully, there remains opportunities for future quantitative studies to be undertaken to add insight to the existing body of knowledge. / Dissertation (MBA)--University of Pretoria, 2014. / zkgibs2015 / Gordon Institute of Business Science (GIBS) / Unrestricted

The history of Tuolumne County during the gold rush

Tremain, Harry C. 01 January 1947 (has links)
Back in the foothills of the Sierra Nevada, in the heart of the Mother Lode, lies Tuolumne County, whose history is rich with memories of the days of forty-nine. It was in this country of yesterdays, during those frenzied days of gold, that men fought and toiled and died for that precious metal. Miners in search of this precious substance penetrated into its forests, prospected up and down its canyons, and climbed its steep and rugged mountains. Towns sprang up overnight and disappeared almost as quickly. The miners were forever moving on to richer diggings in search of the “El Dorado.” The gold rush days found Tuolumne a wild and rough country, with the most varied population of any country in the whole region. Yankees, Mexicans, Englishmen, “Sidney Ducks”, Frenchmen, Germans, Spaniards, Chinese, Negroes, Irishmen, and Chileans rubbed elbows and occasionally fists with each other. The region was full of gamblers, drunkards, fast women and lumps of gold. Before the great rush for gold, California was a quiet, peaceful, sparsely settled land. In 1842, the population was about 5,000, not including the Indians. There were about 4,000 native Californians, 90 Mexicans, 80 Spaniards, 80 Frenchmen, 360 Scotchment, Irishmen and Englishmen, 90 Germans, Italians, and Portuguese. There was little immigration, and by 1847 the population had increased to only 7,000 or 8,000. The pueblos of Monterey, San Jose and Yorba Buena were the principal centers of trade. San Diego, Los Angeles, Sonoma and New Helvetia (now Sacramento) also contained a small population. Then came the discovery of gold. It took a little while for the news to travel, and at first people thought the reports were exaggerated, but as more and more reports were carried back to the pueblos, the excitement increased. On the first of April, 1848, the California Star printed “We are happy to be able to say that California continues to be perfectly quiet…. For more than a year no disorders have occurred, -the native Californians are beginning to mingle with our people, and are gradually turning their attention to agriculture. No further difficulties are apprehended.” Little did the writer of this article dream what was to take place before very long. BY the end of May only about 300 men were in the gold fields. So rapidly did the gold-fever take hold, however, that by the tenth of June, the same newspaper was fearing that every town would be depopulated. It reported that “every seaport south to San Diego and every interior town is drained of human beings.” As yet, of course, the news had not had time to reach the Atlantic states, so the gold rush was purely local, and there were relatively few digging for gold. The Star estimated that there were “1,000 souls washing gold”, and that about $100,000 had been taken from the mines since the first of May from an area about 100 miles in length and 200 miles wide.

Witwatersrand genesis: a comparative study of some early gold mining companies, 1886-1894

Webb, Arthur (Arthur C M) January 1982 (has links)
Preface: For anyone standing on the ridge of the Witwatersrand on a spring day in September 1886 the sight immediately to the south represented a hive of activity and hope. Nearly a hundred years later ample evidence stretches away on both sides of the watershed to confirm the fulfilment of those early sentiments. It is, nevertheless, all too easy to ignore the struggles and failures which marked the beginnings of the world's greatest gold field in the light of its subsequent abundant success. Only when attention is turned to the individual companies formed to exploit the discovery does the true picture emerge of the lack of adequate technological and managerial knowledge amongst the early pioneers and of the financial frailty of their companies. The object of this thesis is to shed light on these beginnings by reviewing the histories of four of the earliest companies established to work the main reef. The approach adopted is to scrutinize the material available with a view to determining the motivations and actions of the managements of the various companies with regard to their economic environment, whether within or without the individual company. Clearly, the availability of information is a major determinant of the success of any such venture and this was particularly so in the case of the companies considered. With the exception of the Barlow Rand Limited holding of the H. Eckstein and Company Archives, which offers an integral coverage of that firm's dealings with the emerging industry, and which is certainly the most comprehensive source of information available to the researcher, little material relating to specific gold mining companies has survived. Under these circumstances it was necessary to rely heavily for information on the local press. These newspapers proved an invaluable source in this regard. As a mining camp with a limited capacity for generating newsworthy incidents, the newspapers of early Johannesburg found an eager readership for information about the industry which lay at the heart of the community. For their part, the managements of the various mining companies found in the pages of the local press an outlet for intelligence both true and false; the press was a useful vehicle for the publication of directors' and annual reports to meet a wider audience, but similarly it could be and was used to disseminate 'spectacular' reports calculated to influence the status of a company's stock on the local share market. As a research source the press has thus to be approached with caution but its value, if the warning is heeded, is in no way diminished. Beyond these two sources the next most valuable accumulation of data on the early industry is "The Gold Fields Collection" housed in the Cory Library for Historical Research at Rhodes University. As a collection it is far from complete and it is to be hoped that the donors will in future see fit to augment it with further material as this becomes available. It neverthess proved an invaluable source for the investigation of at least one of the companies of the study and for a general background to the industry.

Exploring strategy implementation in major South African gold mines / Alida Christina van der Westhuizen

Van der Westhuizen, Alida Christina January 2014 (has links)
It is essential for the survival of the mining industry to look at the effective streamlining of organisations that can survive in the downturn in the gold cycle and meet the state demands placed on the industry. This study outlines challenges in South African gold mines and investigates the fit of the strategy implementation with the theory of implementing strategy on through the combined organisational design approach of looking at organisational structure, strategic and management control systems and organisational culture as well as corporate governance and strategic leadership. The research focus is on the implementation of generic strategies in South African gold mines pertaining to general industry issues such as strategies to address profitability and sustainability, dealing with the regulatory framework in terms of state intervention in the minerals sectors (SIMS), the Social and Labour Plan (SLP) and the Minerals and Petroleum Development Act of 2002, amended 2013 (MPRDA) and socio-economic concerns through the mining charter and wage demands. The purpose of the research is to explore how management perceives the implementation of strategies in general, without specific attention to the strategies developed for the organisation. The research will explore strategy implementation in South African gold mines and test the theory for the implementation of strategy. The research design is a qualitative study with individual semi-structured interviews. Participants were purposefully selected based on their experience in management roles in South African gold mines. The results of testing the developed theory-based strategy implementation against the practical application of strategy implementation shows an acceptable match in terms of corporate governance and strategic and management control systems. Gaps are identified in terms of organisational structure and culture. Strategic leadership and the strategic implementation plan show larger gaps compared to the theory, which is a concern. Though sound strategies may be in place, implementation fails. The absence of strategy implementation plans is noticeable and not linked back to strategic leadership. / MCom (Business Management), North-West University, Potchefstroom Campus, 2014

Die verband tussen ertsgraad, fisiese elektrisiteitverbruik en bedryfskoste in die Suid-Afrikaanse goudmynbedryf, 1965-1982

10 September 2014 (has links)
M.Com. (Economics) / The objective of the thesis was to examine the relationship between the grade of ore, physical electricity consumption and working cost in the South African gold mining industry for the period 1965 - 1982. The South African economy is heavily dependent on the gold mining industry, which is a major earner of foreign exchange and a large consumer of labour and agricultural and industrial output. The industry is also important as a source of finance for both the private sector and the Treasury. Curtailment of activity within the industry by closing down the more marginal mines or by shortening the life of the industry' as a whole because of rising costs and/or a hesitant gold price, will harm the South African economy in a number of ways. The industry has no option but to regard the gold price as given. The remaining ore reserves tend to be of a lower grade and/or to be found at greater depth. Controlling the working costs would seem to be almost the only option open to the industry.

The dynamics of mining towns: the case of Khutsong township, Carletonville

Tunce, Loyiso January 2016 (has links)
A research report submitted in partial fulfilment of the requirements for the Master of Science in Town and Regional Planning at the school of architecture and planning to the University of the Witwatersrand, Johannesburg, 2016 / Mining and the mining experience is one that has been written about extensively in academia. The history of mining in South Africa has not only shaped the physical landscape of the country but has shaped peoples understanding of the different spaces. The changing dynamics of mining, especially gold mining has played a role on the different experiences in contemporary South Africa. The decline in employment and production in the sector has meant that people in these gold mining towns have had to adapt to the changing times. The concept of resilience allows the research to view spaces such as that of Khutsong to see how people in such places are able to be resilient and the factors impacting on their resilience. / MT2017
