Xinyu Dai

Abstract

Aimed at the ore characteristics,the flotation flowsheet of one-stage coarse grinding-bulk flotation of copper and molybdenum-regrinding of bulk concentrate-separation of copper and molybdenum was determined.A combined depressor WL is used in the separation process of copper and molybdenum.After four cleaning flotation,themolybdenum concentrate containing 52.68% Mo with recovery of 89.31% is produced.The grade of copper concentrate is 19.69% and the recovery of copper is 92.50%.The separation of copper and molybdenum is satisfactorily reached.
