| Abstract: |
| Flotation tests,FTIR and molecular mechanics simulation are studied in xanthate-malachite system.It is found that unactivated malachite can be floated with long hydrocarbon chain xanthates while the unactivated malachite can't be floated with ethylxanthate.Characteristic absorption peaks of four kinds of xanthates are detected on unactivated malachite by FTIR.The interaction energy between xanthate and malachite is simulated and calculated by molecular mechanics respectively,it points out that molecular mec... |
