| titleOfInvention | A kind of take alkyl trimethyl quaternary ammonium salt as the thiosulfate gold extracting method of additive |
| abstract | It take alkyl trimethyl quaternary ammonium salt as the thiosulfate gold extracting method of additive that the present invention discloses a kind of, belongs to technical field of wet metallurgy; Adopt traditional thiosulphate leaching method for some ores, leaching yield is low, the larger problem of reagent consumption, carries out the rear reprocessing of modification adjustment to ore pulp; Re-use after the present invention carries out modification to ore pulp and leach containing thiosulphate, quadrol, cupric ion gold leachate, leaching yield is higher than 75%; And technological operation is simple, be easy to control, thiosulphate consumption is extremely low, and Gold leaching liquid composition is simply conducive to the recovery of wherein gold; Applied widely, pH has good leaching effect between 9 ~ 12, and the Gold ore leaching speed for limonite height argillization is fast, and quite high gold leaching rate can be kept, whole carrying in golden process does not use the toxic substances such as sodium cyanide, does not also discharge Toxic waste, environmentally friendly. |
