This book was released on 2000 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A process for the recovery of copper and cobalt from the Kakanda tailings dump was developed and evaluated during an integrated pilot plant campaign at Mintek. The process involved a number of unit operations including leaching, copper solvent extraction, copper electrowinning, iron removal, manganese solvent extraction, cobalt solvent extraction, ion exchange for impurity removal, and cobalt electrowinning. This paper describes the laboratory test programme required to enable the design of an ion exchange circuit for the removal of traces of copper and zinc from the cobalt advance electrolyte, as well as the pilot plant campaign to evaluate the final design.^L^LA resin was chosen for the removal of copper, and occasionally copper and zinc, from the cobalt advance electrolyte. During the pilot plant campaign a lead-lag fixed-bed system was evaluated at a superficial linear velocity of 0.5 cm/s (to be employed on the full-scale plant). The concentration of copper in the ion exchange feed varied between 60 and 100 mg/l and that of zinc between less than 2 and 10 mg/l. Effluent concentrations for both metals of less than 2 mg/l, specified for electrowinning, were consistently delivered for both metals. ^L^LThe full- scale design was based on an ion-exchange feed flowrate of 200 m3/h, and the final dimensions of the two columns were: inside diameter 3.7 m, and height 7.5 m. Variations of copper and zinc concentrations in the ion exchange feed solution were accommodated by changes in the operating strategy of the plant during piloting.

Book Synopsis The Extraction of Copper from Copper-nickel Catholyte by Cation Exchange by :
Download or read book The Extraction of Copper from Copper-nickel Catholyte by Cation Exchange written by and published by . This book was released on 1975 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: The work involved a laboratory study of the selectivity and capacity for copper of IMAC SYN 101 and Lewatit TP 207 resins. The sponsor had stated that the ion-exchange system could be incorporated into a closed process if the nickel content of the copper catholyte did not exceed 10 g/l and the additions of sulphuric acid and water did not exceed plant make-up rates. The average results obtained to date are 43 g of copper and 3 g of nickel per litre of resin. These were obtained under the following conditions: a total number of bed volumes of 8 to 12, a temperature of at least 50 degrees C and a flowrate of 8 to 12 bed volumes per hour. A mass balance based on a three-stage process is included for the whole copper-production circuit. The fixed-column separation entails three stages, ie, loading, scrubbing (removal of entrained feed solution and loaded nickel), and regeneration (replacement of the loaded copper and a minor quantity of nickel with the use of recycled electrolyte from the electrowinning tankhouse). Calculations showed that the circuit is very sensitive to the nickel carry-over into the copper circuit. The results for the resin loading covered a wide range (especially for nickel), and it seems likely that more laboratory work will be required if the project continues. IMAC GT 73, a cation-exchange resin, which was tested for the removal of impurities from nickel catholyte, was found to reduce the copper concentration from 0,25 ppm to less than 0,05 ppm (which is te detection limit). It was decided that a small resin column on-line with one of the cells should be installed at Bindura. Its effect in purifying the solution should be immediately apparent from the quality of the cathode.

Book Synopsis Extractive Metallurgy of Nickel, Cobalt and Platinum Group Metals by : Frank Crundwell
Download or read book Extractive Metallurgy of Nickel, Cobalt and Platinum Group Metals written by Frank Crundwell and published by Elsevier. This book was released on 2011-07-18 with total page 623 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes and explains the methods by which three related ores and recyclables are made into high purity metals and chemicals, for materials processing. It focuses on present day processes and future developments rather than historical processes. Nickel, cobalt and platinum group metals are key elements for materials processing. They occur together in one book because they (i) map together on the periodic table (ii) occur together in many ores and (iii) are natural partners for further materials processing and materials manufacturing. They all are, for example, important catalysts – with platinum group metals being especially important for reducing car and truck emissions. Stainless steels and CoNiFe airplane engine super alloys are examples of practical usage. The product emphasises a sequential, building-block approach to the subject gained through the author’s previous writings (particularly Extractive Metallurgy of Copper in four editions) and extensive experience. Due to the multiple metals involved and because each metal originates in several types of ore – e.g. tropical ores and arctic ores this necessitates a multi-contributor work drawing from multiple networks and both engineering and science. Synthesizes detailed review of the fundamental chemistry and physics of extractive metallurgy with practical lessons from industrial consultancies at the leading international plants Discusses Nickel, Cobalt and Platinum Group Metals for the first time in one book Reviews extraction of multiple metals from the same tropical or arctic ore Industrial, international and multidisciplinary focus on current standards of production supports best practice use of industrial resources

Download or read book African Mining ’91 written by Institution of Mining and Metallurgy and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: The second 'African Mining' conference is planned for June 1991, and follows the first, very successful, event held in May 1987. That full four-year period was characterized by substantial changes in the political and economic climate of many countries in both hemispheres. Copper prices were relatively firm, and the advance and steady demand for nickel and ferrochromium stabilized important sectors of the mineral industry, certainly in Zimbabwe. The promise for gold remained unfulfilled, but the smaller, relatively flexible, mines survived and only the large, deep and low-value mines seem seriously at risk. None of this has affected the hungry, and intensive exploitations from surface to the water-table have revealed many targets of promise to those willing to take the risks. The pattern in Southern Africa was extraordinarily stable among the turmoil, with independence for Namibia, adjustments in South Africa and a gradual shift to market economies in the region. The pace of exploration has increased to recover some part of the progress that was lost in the Independence struggle, and atthe end of the first decade in Zimbabwe, for example, oil is being sought in the Zambesi Rift, following the investigation of the Luangwa in Zambia, and there are exciting exploration projects for methane released from coal, deep in its basins.

Download or read book Extractive Metallurgy of Activated Minerals written by P. Baláž and published by Elsevier. This book was released on 2000-04-28 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mechanical activation of solids is a part of mechanochemistry, the science with a sound theoretical foundation exhibiting a wide range of potential application. Mechanical activation itself is an innovative procedure where an improvement in technological processes can be attained via a combination of new surface area and defects formation in minerals. Mechanical activation is of exceptional importance in extractive metallurgy and mineral processing and this area forms the topic of this book and is the result of more than twenty years of research and graduate teaching in the field. In pyrometallurgy, the mechanical activation of minerals makes it possible to reduce their decomposition temperatures or causes such a degree of disordering that the thermal activation may be omitted entirely. The potential mitigation of environmental pollutants is becoming increasingly important in this context. The lowering of reaction temperatures, the increase of the rate and amount of solubility, preparation of water soluble compounds, the necessity for simpler and less expensive reactors and shorter reaction times are some of the advantages of mechanical activation in hydrometallurgy. The environmental aspects of these processes are particularly attractive. Several industrial processes are examined and their flowsheets are presented as succesful of activation. In these processes, the introduction of a mechanical activation step into the technological cycle significantly modifies the subsequent steps. The book is designed for researchers, teachers, operators and students in the areas of extractive metallurgy, mineral processing, mineralogy, solid state chemistry and materials science.It will encourage newcomers to the mechanochemistry to do useful research and discover novel applications in this field.
Download or read book Flash Smelting written by W. G. Davenport and published by Elsevier. This book was released on 2015-05-11 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flash Smelting: Analysis, Control and Optimization deals with the analysis, control, and optimization of flash smelting. This book explores flash smelting in general and Outokumpu and Inco flash smelting in particular, and also presents a mathematical description for the flash smelting process. A set of mass and heat balance equations that can be used to describe steady state smelting under autogenous or nearautogenous smelting conditions is developed. This text has 20 chapters and begins with an overview of flash smelting and its products; the main raw materials of copper flash smelting; chemical reactions in the flash furnace; impurities in the concentrates that are fed to the flash furnace; and the operation of industrial flash furnaces. Attention then turns to Outokumpu flash smelting, Inço flash smelting, and mathematical representation of flash smelting. The chapters that follow focus on the effects of blast preheat on flash smelting; the combustion of fossil fuel in the flash furnace; and the effect of matte grade on the fossil fuel, industrial oxygen, and blast preheat requirements of flash smelting. Equations are used to determine the effects of such factors as concentrate composition, blast temperature, and dust carryout, and as the basis for optimizing and controlling the flash smelting process. This book will be of interest to both mathematicians and metallurgists.
