| titleOfInvention | Method for leaching gold by virtue of thiosulfate utilizing ammonium alcohol polyvinyl phosphate as additive |
| abstract | The invention provides a method for soaking gold by virtue of thiosulfate utilizing ammonium alcohol polyvinyl phosphate as an additive. 0.1 to 10g/dm<3> ammonium alcohol polyvinyl phosphate is added into leaching pulp, so that the thiosulfate consumption is obviously reduced within a relatively wide pH range (9 to 12), and furthermore, the gold leaching rate can be obviously improved; obtained leaching solution is simple in ingredients and is beneficial to cycle use and gold recovery. In addition, the additive is nontoxic, is capable of reducing the use concentration of ammonia water in the leaching slurry to 0.04 to 0.10mol/dm<3> and is beneficial to environmental conservation. |
