| Abstract: |
| The process of extracting gold using cyaniding reagent from pyrite was studied and the influencing factores of gold leaching rate like concentration of sodium cyanide,leaching temperature and oxidant were determined.The mechanism of strengthened gold leaching process using oxidant was studied.At the conditions of using hydrogen peroxide as oxidant,room temperature,concentration of sodium cyanide is 0.05% and leaching time is 12 h,the leaching rate of gold could reach more than 94%. |
