gold dissolution from ores and recovery systems

Gold Extraction and Recovery Processes for Various methods such as gravity concentration, flotation, panning, pyrometallurgy, cyanidation etc are availe for the extraction of gold metal from its ores Amongst these methods, cyanidation is the most common method used in the leaching of gold from the ore This process involves the dissolution of gold containing ores in dilute cyanide solution in In the treatment of goldbearing polymetallic sulfide mineral ores with high content of valuable heavy metals (such as goldcontaining polymetallic sulphide ores containing copper, copper, zinc, lead, zinc, antimony, arsenic, etc), since these ores contain To eliminate harmful factors, in order to eliminate unfavorable factors, in the actual Lime in Gold Ore Mining Process Flotation, The recoverability by cyanidation of the gold content of sedimentary goldbearing ores containing organic carbonaceous material and goldbearing pyrite, or other goldbearing sulfides, is greatly increased by heating an aqueous slurry of the ore to about 167 176; to 212 176; F and then introducing air or oxygen into the heated slurry to gold bearing sulphide ores Prominer (Shanghai)
