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 The Solvent Extraction of Cobalt, Nickel, Zinc, Copper, Calcium, Magnesium, and the Rare-earth Metals by Organophosphorus Acids written by and published by . This book was released on 1988 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: A series of 26 organophosphorus acids of the dialkyl phosphoric (RO)2POOH, alkyl alkylphosphonic (RO)RPOOH, and dialkylphosphinic acid R2POOH types was prepared for use in studies on the solvent extraction of cobalt, nickel, zinc, copper, calcium, magnesium, and the rare-earth metals. The compounds were characterized by measurement of their physical properties (melting-points, refractive indices, densities, and acid-dissociation constants), and their purities were confirmed by potentiometric titration against standard alkali, by carbon and hydrogen microanalysis and, for liquid products, by comparison of their experimental molar refractivities with empirical values. Metal-distribution equilibria were determined for the extraction of the above-mentioned metals (0,02 M as nitrates) from 0,40 M sodium nitrate solutions into 0,20 M solutions of the organophosphorus acids in toluene at 20 degrees C. For cobalt and nickel, corresponding data were also obtained at 50 degrees C. The application of slope-analysis techniques indicated that the extracted complexes have the stoichiometries Co(HA2)2, Ni(HA2)2(H2O)2, Zn(HA2)2, Cu(HA2)2, Ca(HA2)2(HA)2, Mg(HA2)2(HA)(H2O), and Ln(HA2)3, where H2A2 represents the dimerized organophosphorus acid molecule. Some differences in behaviour were apparent with n-octyl acids, where stoichiometries of NiA2(H2O)2 and LnA3 were found for the nickel and rare-earth (except lanthanum) complexes respectively. The extraction behaviour of the different metals with respect to changes in the structure of the organophosphorus acid is rationalized in terms of the different steric requirements of the respective metal complexes. Correlations between the pH 0,5 values for the extraction of the individual metals and the pKa value of organophosphorus acids provide an indirect estimate of the importance of the contribution of steric factors to the extractability of the metal complexes. The extractants di(3-octyl) and di(4-octyl)phosphinic acid are shown to possess selectivity characteristics superior to those of any previously reported organophosphorus acid with respect to cobalt-nickel, cobalt-calcium, zinc-copper, and zinc-calcium separations. The existence of novel tetrahedral nickel complexes (stoichiometry Ni(HA2)2) with highly sterically hindered phosphinic acids is reported.

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
Book Synopsis The Effect of Reagent Structure on the Extraction and Separation of Nickel and Cobalt by Mixtures of Carboxylic Acids and Pyridine Derivatives by :
Download or read book The Effect of Reagent Structure on the Extraction and Separation of Nickel and Cobalt by Mixtures of Carboxylic Acids and Pyridine Derivatives written by and published by . This book was released on 1999 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effect of alkylpyridines and related compounds upon the extraction of divalent nickel and cobalt from nitrate media by solutions of some carboxylic acids in xylene was studied. Addition of the pyridine compounds caused substantial synergistic shifts in the pH50 values for the extraction of both metals, and these were greater for nickel than for cobalt in any given system. With regard to the influence of the nature of the individual extractants on the extent of the synergistic effects, the shifts in the pH50 values were found to increase with increasing pKa and with increasing steric bulk of the carboxylic acid component. These observations can be rationalized in terms of the ease of replacement of solvating carboxylic acid ligands (HA) by the N-donor ligands (L). In contrast, the synergistic effects were somewhat less dependent on the structure of the pyridine derivative, and the shifts did not usually decrease significantly when L contained an electron-withdrawing group. However, the shifts were greatly decreased when the substituent group on the pyridine ring was located adjacent to the nitrogen atom (i.e. the metal-coordinating site), presumably for steric reasons. Batch countercurrent experiments were carried out with an aqueous feed solution containing 5 gL-1 nickel and 5 gL-1 cobalt, and an organic phase containing 0.50 M 4-(5-nonyl)pyridine and 0.25 M 4-^Itert^R-bytylbenzoic acid. Four extraction stages of pH 4.9 and two scrubbing stages were use to obtain a 99.6% pure nickel product and a 98.7% pure cobalt product. Complete stripping of the loaded organic phase was readily achieved by contact with dilute mineral acid to give an equilibrium pH of 3.0.

Download or read book Agromining: Farming for Metals written by Antony van der Ent and published by Springer Nature. This book was released on 2020-12-07 with total page 482 pages. Available in PDF, EPUB and Kindle. Book excerpt: This second and expanded edition of the first book on agromining (phytomining) presents a comprehensive overview of the metal farming & recovery of the agromining production chain. Agromining is an emerging technology that aims to transform the extraction of sources of target elements not accessible by traditional mining and processing techniques. Agromining, which is based on sustainable development, uses hyperaccumulator plants as 'metal crops' farmed on sub-economic soils or minerals wastes to obtain valuable target elements. This volume is edited and authored by the pioneers in the rapidly expanding field of agromining and presents the latest insights and developments in the field. This book provides in-depth information on the global distribution and ecology of hyperaccumulator plants, their biogeochemical pathways, the influence of rhizosphere microbes, the physiology and molecular biology of hyperaccumulation, as well as aspects of propagation and conservation of these unusual plants. It describes the agronomy of metal crops and opportunities for incorporating agromining into rehabilitation and mine closure, including test cases for agromining of nickel, cobalt, manganese, arsenic, selenium, cadmium, zinc, thallium, rare earth elements and platinum group elements. Since the first edition was published, there have successful nickel agromining field trials in the tropics (in Malaysia and Guatemala), and these are presented in a dedicated case study chapter. Other new chapters focus on the processing of bio-ore for elements other than nickel, such as rare earth elements and cadmium, and on agromining from industrial wastes such as tailings, and industrial by-products and sites. Furthermore, the book features two new chapters that provide a comprehensive assessment of accumulation a very wide range elements from the Periodic Table in various plant species around the globe, and a chapter on practical methods for discovery of hyperaccumulator plant species in the field and in the herbarium. This book is of interest to environmental professionals in the minerals industry, government regulators, and academics.

Book Synopsis The Separation of Cobalt from Nickel Ammonium Sulphate Solution by Solvent Extraction by :
Download or read book The Separation of Cobalt from Nickel Ammonium Sulphate Solution by Solvent Extraction written by and published by . This book was released on 1996 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A solvent extraction process for the extraction of cobalt from nickel ammonium sulphate solution was evaluated. The feed solution containing 50-100 g/L nickel, 06.-1.1 g/L cobalt, 35-45 g/L ammonium sulphate and minor amounts of other base metals, originated from a base metal refinery. Cobalt can be selectively extracted from this solution using 15 vol per cent Cyanex 272 in Shellsol AB to yield a raffinate with a cobalt concentration of below 20 mg/L. After scrubbing the loaded organic phase with a portion of the loaded strip liquor to remove co-extracted nickel, cobalt is stripped from the organic phase with sulphuric acid (150 g/L) to produce a cobalt sulphate solution of at least 90 g/L cobalt, at a Co:Ni ratio of 500:4000.
