Abstract
Dongguashan copper ore is one of a complex copper sulphide ores containing various metal minerals in Tong ling area. In this paper, in order to simplify the complexity of traditional lime process, the process of Cu-S bulk flotation-regrinding-separation is discussed and exploited. A good quality of Cu concentrate and S concentrate are obtained respectively after Cu-S separation by using calcium hypochlorite as depressant. A good separation results are derived through this process, and high efficiency of calcium hypochlorite used as depressant and feasibility of the process are confirmed.
