Cyanidation treatment before the oxidation pulp by the multi-stage cleaning process to remove the excess pressure generated by the oxidation of acid and heavy metals. so after removal of heavy metals in lower cyanide consumption, and to process more economical. cyanation reaction by conventional methods, and industry to find Recycling of carbon in pulp method and other traditional methods, such as zinc precipitation compared to greatly improve the recovery rate of gold [85,107,901] gold from refractory sulfide ores iron gold recovery
Recovery of gold from sulphide ores, including the process, crushing pulp pretreatment with sulfuric acid to prevent oxidation of impurities and decomposition of carbonate, sulfate solution obtained after solid-liquid separation and solid. Solid water into the concentration of 25-60% (solid re- ) pulp. at 135-250 ℃ pressure oxidation slurry while maintaining 40g / 1 sulfuric acid concentration of the dissolved iron, sulfide oxidation, sulfuric acid, and less than 20% of the oxidized sulfur as elemental. add water in the formation of the oxidized material slurry containing 5-15% of weight after solid liquid separation, acid solution and solid iron have the solution to the slurry of step cycle, after washing the solid liquid separation, separation of iron and metal recycling hydrochloric acid to sulfuric acid pretreatment. recovered from the washed solid gold. [85107794] from the gold-bearing iron-sulfide gold ore recovery process which
From refractory gold-bearing sulphide of iron in the process of gold extraction, including: providing a fresh feed and from the subsequent pressure oxidation step from the oxidation of water through the solids feed slurry. For material pulp slurry with a concentration by weight is about 30 - 60%. slurry at a temperature of about 120-150 ℃, total pressure of about 360-6000KPa the case of the pressure oxidation process to produce solid oxide slurry, so that the oxidized part of the solid feed the pulp back to the recycling and solid oxide from the rest of the recovery of gold. [85107774] from refractory gold-bearing iron sulphide concentrates in the process of gold recovery
Recovery of gold from gold-bearing ore containing the process include, handled fine slurry with sulfuric acid solution to decompose carbonate and acid consumption of other impurities; at 135 ℃ ~ 250 ℃ and kept free sulfuric acid concentration of 5-40 g / l under pressure oxidation-treated slurry of iron dissolution, the resulting sulfuric acid, sulfate and oxidation of the sulfide to less than 20% of the oxidized sulfur in the form of elemental sulfur; to the oxidation of water through the slurry to produce solid weight with 5-15 % of the slurry, obtained after solid-liquid separation and oxidation of iron through the solid acid solution; part of the iron-containing acid solution, acid pretreatment step back from the oxidation of solid recovery of gold.
