| Abstract: |
| The flotation separations of the copper and lead sulfide minerals are summarized in this paper.It's pointed that the main flowsheets which are used in the flotation separation between the sulfides are the selective and the bulk, and iso-flotation flowsheets.During the separation,bichromates,sulfites and some other reagents are used as the depressant for the galena.The electrochemical characteristics of pure chalcopyrite and galena mineral are summarized.It's analyzed that electrochemical separation conditio... |
