Evaluating Copper Rougher-Scavenger Flotation Circuit ...

2015/11/04· Liberated grains of galena are about 15% covered into the copper rougher concentrate. Almost all of the remaining liberated galena is recovered in the copper scavenger concentrate. The recovery of liberated grains of sphalerite into the rougher and scavenger concentrate increases linearly with flotation …

2020/07/26· The rougher flotation behavior of a sulfidized copper ore was studied by a series of batch flotation experiments. Response surface modeling ba sed on central composite design was applied to

Parametric Optimization in Rougher Flotation Performance of ...

Flotation experiments were conducted in a Denver type agitated flotation cell at the rougher stage. The experimental results showed that increasing the pH (from 8 to 10) at low agitation rate (1000 rpm) enhanced the recovery from 80.36% to 85.22%, while at high agitation rate (1200 rpm), a slight declination occurred in the recovery.Cited by: 6
