| Abstract: |
| The half industry extraction process for refractory concentrates gold in Danzhai Guizhou province was introduced.The effects of roasting pretreatment,hermetic cyanide leaching,leaching and adsorption of activated carbon were investigated.The results show that the leaching rate of Au can reach 87.74%,the desorption rate of Au reaches 98% and the total of recycling rate reaches 72.38%. |
