This book was released on 1980 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Some of the current research-and-development programmes in South Africa are reviewed, including those involving the extraction metallurgy of gold, uranium, ferrochromium, ferromanganese, and the platinum-group metals, and the transfer of technology to the industry. The motivation for such research and development is the reduction of capital and operating costs, the improvement of existing processes by computer-assisted control and optimization, the development of new processes for ores not previously exploited, the optimization of energy consumption, and the further processing of minerals to intermediate and end products. In a country with a limited amount of highly-trained manpower, the optimization of metallurgical research and development has to be based on good technical interaction between the mining and metallurgical industries and their in-house laboratories on the one hand, and the national laboratories on the other. In addition, the successful transfer of technology from the research-and-development phase to industry is essential. The examples quoted demonstrate that the local metallurgical industry is supported by a vigorous research-and-development effort that should generate confidence in South Africa's continued large-scale supply of raw and processed mineral products at competitive prices.

Download or read book The Role of Technology in the Development of South Africa's Mineral Industries written by and published by . This book was released on 1994 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The author, in stressing the importance of innovative technology in the development of the mining and metallurgical industries, shows how this was true in the past and the present in South Africa, taking his examples from the gold, uranium, platinum, ferro-alloy, and industrial-minerals industries. He emphasizes the need for industrial expansion in South Africa, and outlines how this can be achieved by the further development of the stainless-steel, manganese, titanium, and precious-metal industries. He then discusses the ways through which such development can be brought about: increased recoveries, new technologies, process control and optimization, reduced energy consumption, recovery of by-products, and recycling of scrap materials.

Book Synopsis Arms Trade and Economic Development by : Jurgen Brauer
Download or read book Arms Trade and Economic Development written by Jurgen Brauer and published by Routledge. This book was released on 2004-08-02 with total page 447 pages. Available in PDF, EPUB and Kindle. Book excerpt: Countries that spend scarce resources to import arms from abroad often require arms sellers to 'reinvest' part or all of the proceeds back into the arms-importing country. These so-called 'arms trade offsets' are therefore thought to enhance domestic economic development. But does this process actually succeed? This book examines the theory and policy applications of arms trade offsets and looks at more than a dozen case studies drawn from across Europe, Africa, Asia, and the Americas. The chapters, based on original research and published here for the first time, are all written by leading experts. That an impressive, lucid and cohesive volume such as this will interest defence economists can be taken almost for granted. The book will also be a useful and enlightening read for those interested in international development economics, military studies and policy-makers across the globe.
Book Synopsis The Use of Computers in the South African Ferro-alloy Industry by :
Download or read book The Use of Computers in the South African Ferro-alloy Industry written by and published by . This book was released on 1982 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The growth of the ferro-alloy industry in South Africa has been accompanied by developments in electric-furnace technology and an increase in furnace capacity. It soon became clear that stricter control of furnace operation was necessary, especially in the larger furnaces, if optimum production was to be achieved. In 1974 a research team set up by the Council for Mineral Technology (formerly the National Institute for Metallurgy) and a large ferro-alloy producer started investigating the control of a large submerged-arc electric furnace, their objectives being to install a computer system, to increase their understanding of the process, to devise strategies to improve the furnace operation, and, in the long term, to optimize the process. An account is given of the first system installed - a minicomputer system that was responsible for the acquisition and storage of data on the status of the furnace at all times, and for the development of off-line programmes for metallurgical control of the process. As the project developed, it became clear that control of the raw-material feed and electrode-hoist position were unsatisfactory. The analogue system for the batching of raw materials was changed to a system that controls the automatic feeding of raw materials according to a preset recipe, controls the dry mass of the reducing agent, and compensates for any errors that occurred during the previous batching. Electrode control was achieved through a system that depends on phase resistances, which are calculated from reliable measurements made in the furnace. Both these controllers were designed and developed as stand-alone microcomputer units. Although there is still much room for improvement in the production of ferro-alloys in South Africa, a lack of skilled manpower will probably delay the implementation of computer control on the whole plant operation as has been achieved overseas.

Book Synopsis Extractive Metallurgy of Niobium by : A.K. Suri
Download or read book Extractive Metallurgy of Niobium written by A.K. Suri and published by Routledge. This book was released on 2017-11-13 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: The growth and development witnessed today in modern science, engineering, and technology owes a heavy debt to the rare, refractory, and reactive metals group, of which niobium is a member. Extractive Metallurgy of Niobium presents a vivid account of the metal through its comprehensive discussions of properties and applications, resources and resource processing, chemical processing and compound preparation, metal extraction, and refining and consolidation. Typical flow sheets adopted in some leading niobium-producing countries for the beneficiation of various niobium sources are presented, and various chemical processes for producing pure forms of niobium intermediates such as chloride, fluoride, and oxide are discussed. The book also explains how to liberate the metal from its intermediates and describes the physico-chemical principles involved. It is an excellent reference for chemical metallurgists, hydrometallurgists, extraction and process metallurgists, and minerals processors. It is also valuable to a wide variety of scientists, engineers, technologists, and students interested in the topic.

Available in PDF, EPUB and Kindle. Book excerpt: Since the early 1970s, the South African gold-mining industry, for decades dominated by a set of fixed and unchanging features, has undergone a transformation. Above all, it is in the area of labour relations that changes have been most rapid and profound. Faced with a crisis in traditional patterns of labour recruitment, the mines have been forced to revise their sourcing and recruiting strategies and in so doing have struck at the heart of the migrant labour system. At the same time, in an attempt to contain the crisis of control, the mines have, for the first time in a hundred years, permitted trade unions to organise among workers, and in consequence the National Union of Mineworkers (NUM) has emerged as a powerful force in the industry. These processes are the subject of Wilmot James's sociological and historical study of African mine workers, which provides the first major account in twenty years of labour in South Africa's gold industry. In his lucid and original analysis, based on material much of which was not previously available to researchers, Wilmot James traces the interlocking developments which have brought about a transformation in the gold industry, and relates these to wider processes of change in contemporary South African society.
