Book excerpt: In order to meet the stringent specifications associated with the prodution of LME Grade A cobalt cathode, producers need to ensure that number of impurities,including Cd, are removed from the advance electrolyte to ppb levels (~0.1 mg/L). Conventional options include ion exchange using amino methyl phosphonic acid resin and solvent extraction using D2EHPA. More recently a Cd-selective resin, employing Molecular Recognition Technology (MRT), become available from IBC Technologies, inc. These three potential unit operation were evaluated in parallel at Mintek. MRT was identified as the most technically feasible option. Results obtained on a cobalt advance electrolyte,containing 55 g/L Co, 6 mg/L Cd and 60 g/L Na2SO4, are presented in this paper.

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 Cobalt and Nickel Removal from Zinc Sulfate Electrolyte by Solvent Extraction and Precipitation Techniques by : Richard G. Sandberg
Download or read book Cobalt and Nickel Removal from Zinc Sulfate Electrolyte by Solvent Extraction and Precipitation Techniques written by Richard G. Sandberg and published by . This book was released on 1978 with total page 500 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sphalerite concentrates prepared during processing of Missouri lead ores contain small percentages of cobalt and nickel which adversely affect zinc electrolysis. The Bureau of Mines has evaluated solvent extraction and precipitation techniques to remove and recover cobalt and nickel from zinc sulfate solution prior to zinc electrolysis. Prepared zinc sulfate solutions containing about 190 gpl of zinc and 50 ppm of both cobalt and nickel were treated using various combinations of complexing reagents, solvent, pH, concentration, time, and temperature. The following complex reagents gave the best results a-nitroso-ßnaphthol, ß-nitrosos-a-napthol, 1,2 cyclohexane dione dioxime (nioxime), di-2-pyridyl ketone oxime, and dimethglyoxime. These reagents in suitable solvents lowered the cobalt and nickel levels to

Available in PDF, EPUB and Kindle. Book excerpt: Actuellement, prêt de 20%% de la production mondiale de cobalt, soient prêt de 10 000 tonnes et 60%% de la production mondiale de super-alliages à base de cobalt sont récupérés par les USA qui considèrent ce métal comme hautement stratégique au point que sa carence pourrait affecter sérieusement ses domaines économiques, industriels et militaires ainsi que ceux de nombreux pays hautement industrialisés. On trouve ainsi dans cet ouvrage des informations sur l'origine, l'élaboration du cobalt, son recyclage et son utilisation tout cela illustré de près de 80 flow-sheets, croquis et graphes. Cet ouvrage est un recueil, une mine d'informations, d'expériences et de pratiques industrielles utiles à avoir pour mieux connaître l'un des métaux le plus influent sur l'échiquier stratégique et économique mondial.
