The effect of biopolymer dispersants on copper flotation in ...
Copper recovery increased from 85% to 90%, 94% and 93% at the end of flotation, in the presence of DP 1777, DP 1775 and DP 1778, respectively. DP 1775 and DP 1778 had a better effect on copper recovery than DP 1777. The presence of biopolymers also led to an increase in flotation rate, seen as the higher copper recoveries in the first concentrate.
