摘要： Provided is a mineral processing method that allows obtaining a concentrate having a low arsenic grade from a raw material having a high arsenic grade. The mineral processing method includes: a repulping step of adding water to a raw material containing a non-arsenic-containing sulfide mineral as a sulfide mineral not containing arsenic and an arsenic-containing sulfide mineral as a copper sulfide mineral containing arsenic to obtain a mineral slurry; a pH adjusting step of adjusting a pH of a liquid phase of the mineral slurry to 10 or more; a conditioning step of adding an oxidant and xanthate alkali metal salt to the mineral slurry; and a flotation step of performing flotation using the mineral slurry to separate the raw material into a floating ore having a grade of the non-arsenic-containing sulfide mineral higher than a grade of the non-arsenic-containing sulfide mineral of the raw material and a precipitating ore having a grade of the arsenic-containing sulfide mineral higher than a grade of the arsenic-containing sulfide mineral of the raw material. The raw material contains the arsenic by 4.4 to 5.8 pts. wt. per 100 pts. wt. of copper.

摘要： A method of operating a concentrator may comprise producing a final copper concentrate and periodically or continuously analyzing the produced final copper concentrate to obtain a grade value of the produced final copper concentrate. The produced final copper concentrate may be sent to a downstream smelting operation if/when the grade value of the produced final copper concentrate is at or above a minimum acceptable grade threshold and may be sent to a downstream hydrometallurgical operation capable of producing copper cathode, if/when the grade value of the produced final copper concentrate is below or falls below the minimum acceptable grade threshold.

摘要： A hydro-metallurgical method 80 for the removal of uranium, thorium, radium, lead, bismuth and polonium and/or other radionuclides from a radioactive copper concentrate to produce an upgraded copper concentrate having lowered emission levels. The method comprises the step of: subjecting the copper concentrate to an acidic leaching process (NONOX leach) 120 using a sulfate and chloride containing lixiviant under electrochemically controlled conditions, to allow at least partial removal of one or more of the radionuclides to produce the lowered emission upgraded copper concentrate, wherein the leaching process is conducted at elevated temperature and under pressure to suppress boiling in the leaching process.

摘要： The present invention relates to flotation of sulfidic copper-molybdenum- and gold-containing minerals. More specifically, the invention relates to sulfoxy reagent-assisted floatation for separating of sulfides of copper, molybdenum and gold from pyrite, marcasite, pyrrhotite, arsenopyrite, and other gangue minerals following aerating by an oxidizing gas and contacting by a sulfoxy reagent. To promote collection and flotation the feed mineral materials are preferably not contacted with an externally generated non-oxidizing gas to lower the dissolved molecular oxygen content prior to flotation.

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.
