| Abstract: |
| A gold concentrate in Yunnan province with the ore of gold bearing oxidized ore, quartz vein type gold deposit by the process mineralogy studied. The grade of gold is 38.23g/t, and the silver is 28.82g/t, There are can be recoveried with together, and it is contains As, Cu, As, Sb and so on, but there are not high, however，the carbon is higher, it is will be influence the leaching of gold and silver. The study found that use the direct cyanide leaching with stir can obtained a good indicator of the gold leaching rate was 93.12%. |
