Available in PDF, EPUB and Kindle. Book excerpt: Copper-nickel-sulphide ores mined in the Rustenburg district of South Africa are generally smelted in electric furnaces because of the high-temperature slag produced, the availability of cheap electric power, and the smaller pollution problems. Apart from melting, the functions of the electric furnace are to recover most of the matte content in the converter slag by physical and chemical interaction with the furnace bath and to provide adequate time for the optimum separation of matte and slag. Smooth, efficient operation will depend on fluid slags for settling, balanced by high resistivities to obtain adequate concentration and distribution of power by way of current heating. To obtain a greater understanding of the processes involved, an investigation was undertaken at Rustenburg Platinum Mines on the smelting of copper-nickel concentrates in a 19.5 MVA furnace with six in-line electrodes. The matte- and slag-tapping temperatures, slag temperatures, slag analyses, electrical data, and electrode position were measured. Radioactive tracers were introduced into the slag, and quantitative results relating to the flow pattern within the furnace were obtained. These studies were augmented by scaled laboratory investigations relating to the determination of cell constants and current distribution within the furnace. Instantaneous field and power distribution plots were determined by use of an on-line mini-computer. The applicability of these results to furnace operation is discussed. The furnace investigations showed that the slag was very homogeneous except at either end of the furnace where there was an increase in concentration of chromium oxide at the slag-matte interface. This increase was shown to originate from the local ore. Radioactive tracer tests confirmed that the slag was very well mixed along the length of the furnace, about 65 per cent of the slag volume being accounted for by backmix. The tests offered a means of comparison of the flow conditions in the reverberatory and electric furnaces. Model experiments gave insight into the mode of current flow and power distribution within the furnace. The model experiments and actual furnace measurements enabled a cell constant to be derived for the calculation of the furnace resistance, which was in reasonable agreement with the actual operation.

This book was released on 2019-02-01 with total page 2258 pages. Available in PDF, EPUB and Kindle. Book excerpt: This landmark publication distills the body of knowledge that characterizes mineral processing and extractive metallurgy as disciplinary fields. It will inspire and inform current and future generations of minerals and metallurgy professionals. Mineral processing and extractive metallurgy are atypical disciplines, requiring a combination of knowledge, experience, and art. Investing in this trove of valuable information is a must for all those involved in the industry—students, engineers, mill managers, and operators. More than 192 internationally recognized experts have contributed to the handbook’s 128 thought-provoking chapters that examine nearly every aspect of mineral processing and extractive metallurgy. This inclusive reference addresses the magnitude of traditional industry topics and also addresses the new technologies and important cultural and social issues that are important today.
