| Abstract: |
| According to characteristics of Yunnan tin copper sulfide ore of arsenic content high, Technology for arsenic inhibition by floating copper, Combined agent which is arsenic minerals restrained and copper mineral collecting agent. It can effectively reduce the content of arsenic in copper concentrate by rough selection 、One sweep 、five selection,Copper concentrate in which copper grade is12.63%,recovery of copper is 73.71%,content of arsenic minerals is 0.425% was gained by final closed circuit test. |
