摘要： In one aspect, the invention provides processes for producing an enriched copper concentrate from a copper-and-nickel-containing ore. Processes of the invention may include an initial step of comminuting the ore, to provide a ground ore comprising copper minerals and nickel minerals. The ground ore may be subjected to a floatation process, to separate the ground ore into distinct fractions, such as first and second concentrates. A first concentrate may for example be made up of copper-enriched-and-nickel-containing solids, while a second concentrate is made up of nickel-enriched-and-copper-containing solids. The floatation process may for example fractionate the ore so that the concentration of copper minerals is higher in the first concentrate than in the ore, and the concentration of the nickel minerals is higher in the second concentrate than the ore.

摘要： A process for the extraction of a precious metal, such as gold or silver, from a sulphide ore or concentrate or other source material comprises subjecting the source material to pressure oxidation to produce a pressure oxidation slurry. The pressure oxidation slurry is flashed down to a lower temperature and pressure and is then subjected to a liquid/solid separation to obtain a pressure oxidation solution and a solid residue containing the precious metal. The solid residue is then subjected to cyanidation to extract the precious metal. The formation of thiocyanide during cyanidation is minimized or counteracted by effecting the cyanidation at an elevated oxygen pressure and a reduced retention time, such as 30 to 90 minutes. A method for the reduction of copper cyanide formation during cyanidation leaching is also provided.

摘要： A process for leaching a value metal from a base metal sulfide ore, comprising the step of leaching the ore with a lixiviant comprising a chloride, an oxidant and hydrochloric acid is disclosed. The leaching is controlled, by use of low concentrations of hydrochloric acid and a redox potential, to effect formation of hydrogen sulfide from the base metal sulfide ore. The hydrogen sulfide is stripped from the leach solution, thereby reducing the amount of sulfate generated in the leach to very low levels. The leaching may also be conducted to limit the co-dissolution of platinum group metals and gold with the base value metals. The leach forms a value metal-rich leachate and a solids residue. The solids residue may be subsequently leached to recover the platinum group metals and gold. The value metal-rich leachate can be oxidized and neutralized to recover the value base metals. In an embodiment, the chloride is magnesium chloride and lixiviant solution is regenerated.
