    refractory gold ores: challenges and opportunities for a key capital costs per metric ton of ore capacity are higher in refractoryore projects. construction of processing plants with pox circuits (the technology that recently became the most popular to treat difficult ore) requires approximately 48 percent higher investments compared to plants with regular tankleaching processes (exhibit 3). effect of agitation intensity on the biooxidation process of various views persist about the effect of the agitation intensity on the mineral biooxidation process, but the mechanism remains unclear. in this study, the effects of the agitation intensity on the biooxidation process of refractory gold ores by acidithiobacillus ferrooxidans were investigated in experimental stirred tank bioreactors (strs). gold and silver leaching by cyanidationthe higher the density of the feed to the agitator the greater the capacity of the agitator, or conversely, smaller or fewer agitators are required. assuming an ore where the solids have a specific gravity of 2.6, one ton of solids as 30% solids (70% solution) will occupy 86.7 cubic feet, while at 50% solids will only occupy about half that refractory gold ore treatment methodsjan 11, 2018 · the process consists of ultraline grinding of ore or concentrate followed by oxidative leaching at atmospheric pressure in agitated tanks. the leach residue is then processed via conventional cip. the key control parameters arc the particle size of the leached solids, the temperature and acidity of the leach and the oxidation potential. effect of agitation intensity on the biooxidation process of in this study, the effects of the agitation intensity on the biooxidation process of refractory gold ores by acidithiobacillus ferrooxidans were investigated in experimental stirred tank slag ore smelting. in nature, iron, copper, lead, nickel and other metals are found in impure states called ores, often oxidized and mixed in with silicates of other metals. during smelting, when the ore is exposed to high temperatures, these impurities are separated from the molten metal and can be removed. us5536297a gold recovery from refractory carbonaceous ores the oxidized ore slurry is mixed with a thiosulfate salt lixiviant, which mixture is maintained at a ph between 7 and 8.7 while the slurry is agitated in a stirred tank reactor system having agitated leach tanks. gold is recovered from the goldbearing leachate by cementation, adsorption on an adsorbent, or cyanidation. us5536297a gold recovery from refractory carbonaceous ores the oxidized ore slurry is mixed with a thiosulfate salt lixiviant, which mixture is maintained at a ph between 7 and 8.7 while the slurry is agitated in a stirred tank reactor system having agitated leach tanks. gold is recovered from the goldbearing leachate by cementation, adsorption on an adsorbent, or cyanidation. slag ore smelting. in nature, iron, copper, lead, nickel and other metals are found in impure states called ores, often oxidized and mixed in with silicates of other metals. during smelting, when the ore is exposed to high temperatures, these impurities are separated from the molten metal and can be removed. 3siltation of ore particles in leaching tanks: causative a potential alternative to cyanide is the salt of thiosulphate which has a faster kinetics, is nontoxic and good for the treatment of refractory gold ores containing carbonaceous matter.
