| Abstract: | Discussed on production application of the new rough concentrate pre- classification technology in Sizhou concentrator,Dexing copper mine. The new technique process was used in second re- grind classification; the granule concentrate was pre- separated from rough concentrate,the circulating load of ball mills was decreased,with one ball mill machine operation was decreased,cost was also decreased and over mill process was avoided; The overflow particle size composition was improved,and secondary copper recovery rate was increased by 0. 2%. |
