| Abstract: | A method of increasing recoveries of gold,silver and copper for the gold concentrate containing arsenic and copper cyanided after roasting pretreatment is presented.The method that the gold concentrate adding sodium sulfide is roasted could effectually raised the recoveries of gold,silver and copper.The text results showed that the method could increased the cyanide leaching recoveries of gold,silver and copper respectively by 8.22%,57.43% and 7.82% but didn't affect making sulfate acid and electrolysising copper. |
