| Abstract: | Copper removal process was studied by oxidative precipitation Experimental from containing copper cyanide solution in this paper. oxidation reagent dosage, copper removal and precipitation pH, oxidation and precipitation test of time off copper conditions were carried out. The results showed that in the condition of cyanide expensive liquid inthe oxidizing reagent 0.25kg/m3 oxidation of 2 hours, adjust the oxidation of liquid solution pH = 10.50 precipitated one hour, the oxidation precipitation after liquid solution of copper cyanide ratio is less than 1. After activated carbon adsorption, gold grade, gold loaded carbon to reach 3.50kg/t, coppergrade only 1-2kg /t. |
