Copper Flotation - Mineral Processing Metallurgy

2016-5-16  While good results are often obtained with ethyl xanthate alone as a promoter, the addition of a small quantity of one of the higher xanthates is frequently found to improve the recovery of those minerals that are not readily floated by the lower xanthate, especially those that are tarnished or oxidized, but since the action of a higher xanthate is, as a rule, more powerful than that of the ethyl compound, it is usually best

Probability density function of bubble size based

2014-8-1  The copper flotation process contains a roughing circuit, a scavenging circuit and a cleaning circuit. These circuits will ensure both high grade in the final product and high overall recovery. In order to improve recovery efficiency, the concentration of the scavenging and the tailing of the cleaning need to be regrinded for re-flotation.
