| Abstract: |
| On the basis of the study on flotation separation of arsenopyrite from polymetallic sulfide ore,CaCl_2 as a depressant which can be used in depressing arsenopyrite,has been developed The As contents of concentrates can be reduced to below 0 5% The new technology has been successfully used in industry,and high economic profit has been obtained |
