摘要： The invention relates to a method for the extraction of precious metals, using halogens. It has been found that introducing halogens in the reactor in the form of hypohalites rather than free halogens simplified greatly the recycling of halogens by electrolysis. It increases the rate of addition of the halogens and significantly reduces secondary reactions with base metals such as iron. Operating under acidic conditions, the gold recovery has been found as high with hypochlorite as with elemental chlorine, with an active chlorine to ore ratio reduced by a factor of two to five.

摘要： The present invention provides a novel separation reagent capable of obtaining a high extraction % of rhodium in a chlorine-based acid solution, which has never existed heretofore, and a method for separating and recovering a platinum group metal using the same. An organic phase composed of an amide-containing tertiary amine separation reagent represented by the structural formula shown below is brought into contact with an acid solution containing a platinum group metal, thereby extracting rhodium, platinum and palladium with the organic phase. Among the metals extracted with the organic phase, rhodium is selectively back-extracted with a highly-concentrated hydrochloric acid solution, while palladium and platinum are back-extracted with a highly-concentrated nitric acid solution: wherein at least one of R1, R2 and R3 represents an amide group represented by: R1 to R3 other than the amide group and R4 to R6 represent a group selected from an optionally branched chain hydrocarbon group of 1 to 18 carbon atoms, an alicyclic hydrocarbon group of 1 to 10 carbon atoms, and an aromatic hydrocarbon group of 1 to 14 carbon atoms.

摘要： The copper sulfide ore is leached in the halide bath without using a special oxidant but with the use of only air. The copper and gold in the copper sulfide ore can be leached at high leaching ratio.The treating steps are as follows. (1) Copper leaching process (CL). The raw material is charged into the first acidic aqueous solution, which contains cupric chloride, ferric chloride, 7 g/L of hydrochloric acid, and sodium chloride. The post-leach liquor contains copper in cuprous state ions and copper in cupric state ions. (2) Solid-Liquid separation step. The resultant solid and liquid of CL step are separated. (3) Air oxidation step (OX). Air is blown into the post solid-liquid separation liquor. The copper in cuprous state ions are oxidized to the copper in cupric state ions. The iron leached in the step (1) is oxidized. Simultaneously, the impurities leached in the step (2) are precipitated. (4) Copper extracting step (CEX). The copper is recovered from the post-liquor of the step (3) (5) Gold recovering step (AL). The residue separated in the step (2) is added to the leach liquor similar to that of the step (1). The steps (1) and (5) are carried out under the atmospheric pressure and at the temperature of boiling point or lower, while blowing air into the leach liquor.

摘要： A process of leaching gold comprising the steps of: a) leaching copper from copper sulfide ore material that contains gold or contains silicate ore containing gold until the copper grade is reduced to 7.9 wt % or less; b) mixing the resulting material having a copper grade of 7.9 wt % or less with a gold leaching solution selected from the group consisting of a first solution containing chloride ions and ferric ions, and a second solution containing chloride ions and iron ions, the iron ions having been oxidized to trivalent ferric ions by air bubbled into the second solution; c) adjusting the pH of the gold leaching solution to 1.9 or less with stirring to leach at least gold in the material into the gold leaching solution by the oxidative activity of the ferric ions contained in the gold leaching solution, wherein the concentration of gold is reduced by selectively removing gold from part or all of the gold leaching solution during gold leaching. This process efficiently leaches at least copper and gold from a copper sulfide ore.

摘要： The invention relates to a method for recovering gold from an intermediate product or residue containing sulphur and iron generated in the leaching of a sulphidic raw material. The recovery of gold and the other valuable metals in the raw material takes place in a chloride environment. The gold contained in the intermediate product or residue is leached with divalent copper and chlorine in a copper (II) chloride—sodium chloride solution in conditions where the oxidation-reduction potential is in the range of 650-750 mV and the pH between 1 and 1.6. The acid generated during the feed of chlorine is neutralized with a suitable alkali. Neutralization avoids the costs of dissolving the iron.
