Abstract:
The purpose of this research was to investigate the extent to which strategic foresight was used by business leaders with a focus on the South African Platinum Mining Industry. The motivation for the research was the reports of prevailing conditions in the mining sector, which brought into question the level at which strategic foresight was used in planning. This raised a further question of whether academic research of the past 50 years was perceived as valuable by organisational leaders. Because strategic foresight is a managerial tool that, among other things, takes into consideration the

Abstract:
The growing importance of managing employee relations and productivity in the platinum mining industry - one of South Africa s most significant employers - has made investigating employee engagement imperative, particularly in light of the 2014 platinum strike, the longest and most expensive in the country s history. As employee engagement is viewed as crucial for business success, this study aimed to ascertain the current levels of employee engagement in the large South African platinum mines, what the key drivers of engagement are, and whether these drivers differ between management and empl

Abstract:
Pay is the main concern of employers, as it affects motivation and productivity. How well the firm motivates its workers is important in achieving the firm s set goals since motivation increases productivity. Motivated workers help make the company profitable. Pay is a powerful motivator for general workers, and no other motivation or motivational techniques is better than money. General workers performance is driven by the motivation to exert more effort in their job.

Abstract:
The current weak state of the platinum market, as well as the large inventory of platinum group metals held by Russia, necessitates that the South African platinum mining industry must carefully evaluate the benefits and disadvantage of small-scale mining of shallow, open castable ore resources. Until the late 1980's, these resources were ignored due to the metallurgical complexities of treating oxidized ore, as well as the mind set that existed within the South African mining industry which militated against open cast mining in the Bushveld.

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

Platinum mining is of special importance, since the largest percentage of the world’s reserves of platinum group metals are found and mined in South Africa.

Metaltolerance maybe conferred to these organisms by mobile genetic elements such as plasmids.

Abstract:
The platinum market is best understood through a comprehensive analysis of supply and demand. Supply is most significantly affected by production constraints and the erratic draw-down in Russian stockpiles. Total world supply of platinum for 1998 amounted to 5.915 Moz, 64% of which was produced from the Bushveld Complex in South Africa. The remainder emanated from Russia, Zimbabwe, the United States, Canada and the recycling of autocatalysts. Supply is forecast to drop by 320 000 oz in 1999 due to a lower Russian export quota and reduced Zimbabwean production. Demand for platinum is u

Abstract:
Trithiocarbonates (TTCs) with less than six carbon atoms per molecule historically have proved to be better bulk sulphide mineral collectors than conventional dithiocarbonates (DTCs). However, high vapor pressures of the short-chain mercaptan decomposition products prevented them from general industrial use. Impala’s commitment in TTC development changed in 2002 when the nC12-trithiocarbonate indicated strong synergism when added to their existing flotation suite. A concerted research effort at the University of Utah followed, and in particular on their surface chemistry. To compliment current

Abstract:
Benchmarking of selected energy use indicators and related best practices definition are helpful tools in establishing an effective energy reduction and energy efficiency strategy. The current energy scarcity exposed by electricity supply shortage in South Africa is an opportunity to assess and determine consumption limits for major consumers, including the mining sector for which gold and platinum producers are among the highest consumers. This dissertation develops, using a survey questionnaire, visits on mine sites and interviews for data collection and analysis, a range of energy co

Abstract:
Labour disruptions, operational cost increases, mineral price decreases and nationalisation are only a few of the financial risks faced by mining companies in South Africa. These risks are not only impacting the mining companies but have a rippling effect on the surrounding communities and the country’s economy. With the South African Platinum Group Metals (PGM) largely affected, platinum mining companies are reviewing all possible cost savings strategies. Together with the help of Eskom’s Integrated Demand Management (IDM) programmes, various electricity cost savings strategies are being inve

Abstract:
M.Phil.<br>The mining industry in South Africa is in a process of transformation, which can be ascribed to various influences. First and foremost is the process of the conversion of mineral rights, employment equity and black economic empowerment. The ethnic distribution of mining employees at the time of the study reflected that Managers were predominantly white, the majority of Shift bosses were white and Miners were predominantly black. Central to the transformation process is maintaining and improving production output in a safe manner. Leadership in addition also impacts on health and saf
