In order to illustrate the generic factors involved both in evaluating flotation flowsheets and

Selectivity and power of frothers in copper ore flotation

Selectivity and power of frothers in copper ore flotation 519 Figures 1 and 2 show that the concentrate yield (Fig. 1) and copper recovery (Fig. 2) are dependent on the type and dose (concentration) of frother. Higher frother dose yielded higher mass and copper recoveries. The flotation results seem to

EVALUATION OF ORGANIC CARBON SEPARATION FROM COPPER

amount of shale in the flotation concentrate leads to a decrease of beneficiation effi-ciency. This also leads to an increase of unwanted elements such as arsenic, lead, or-ganic matter in the concentrate. Greater amounts of shale complicate copper ore con-centration process and cause lower copper recovery at the assumed concentrate grade
