These variations can be caused by unmatched or degrading equipment performance, which can be minimized overall plant capacity and thus a decreased product quality (Major ...
Copper Ore
This process causes small Cu–Fe–S and Cu–S mineral particles to become attached to air bubbles rising through a finely ground ore slurry (Fig. 1.5). Selectivity of flotation is created by using chemical reagents (collectors) that make the Cu minerals water-repellent while leaving waste minerals covered by water (i.e., wetted).
