摘要： Copper is extracted from aqueous copper leach solutions wherein the leach solutions have a temperature of at least 30°C. The method comprises contacting the aqueous solution with an extraction reagent of the formula (I) : wherein R is a linear or branched C10-18 alkyl group and R1 is H or CH3. These extraction reagents do not undergo any significant degradation normally encountered with the use of conventional reagents in leach solutions having temperatures equal to or greater than 30°C.

摘要： A process for the extraction of Ni/Co values from an ore or concentrate comprises the steps of subjecting the ore or concentrate to pressure oxidation in the presence of oxygen and an acidic solution containing halide, copper and sulphate ions to obtain a liquor containing Ni/Co values from the resultant pressure oxidation slurry. The liquor is subjected to a selective precipitation treatment to obtain a solid containing Ni/Co hydroxide. The solid is subjected to a Ni/Co leaching stage with an ammonium solution to produce a leach solution containing Ni/Co values and a residue. The Ni/Co values are separated by solvent extraction to produce solutions suitable for electrowinning of Ni and Co. The process also provides for the recovery of precious metals and other metals such as copper.

摘要： A process for the extraction of a metal from an ore or concentrate comprises subjecting the ore or concentrate to pressure oxidation in the presence of oxygen and an acidic solution containig halogen ions and a source of bisulphate or sulphate ions, such as H2SO4. The metals which can be extracted by the process comprises copper as well as non-cuprous metals such as zinc, nickel and cobalt.
