| titleOfInvention | Method for processing anode slime of copper electrolysis |
| abstract | An object of the present invention is to develop a copper electrolyte wet treatment process capable of efficiently separating platinum group, gold, selenium and tellurium, and efficiently separating and recovering selenium and tellurium.n n n As a solution, the copper electrolytic material is subjected to pretreatment via a decopper process, a chloride leaching process, and a gold extraction process, and the obtained gold extract liquid has a concentration of chlorine ion of 1.5 mol / l or less. Platinum sulfide, gold, selenium, and sulfur remaining in the rear liquid by blowing at a temperature of 60 to 90 ° C. and diluting sulfurous acid gas diluted to 8 to 12% by air at an amount of 8 to 15 times the concentration of platinum group and gold mol. The tellurium is separated to obtain a platinum group-containing gold reducing product. Subsequently, the sulfurous acid gas was kept at a temperature of 60 to 90 ° C. while maintaining the chlorine ion concentration in the liquid at 2.0 mol or less and the selenium concentration in the solution at 3 g / l or more. Blowing is performed at twice the molar concentration of selenium, and selenium and tellurium are separated to obtain a selenium-containing reduced product. Furthermore, sulfuric acid gas is blown to the after-separating selenium at the temperature of 60-90 degreeC, and a tellurium-containing reduced product is obtained. |
