Flotation of a Refractory Copper Oxide Ore Using Ammonium Bicarbonate as Activator

Abstract:

Flotation of Jinping refractory copper oxide ore activated by a combined reagent of amine and ammonium has been fully studied in present study. The results show that the combined reagent (i.e., ethylenediamine phosphate and ammonium bicarbonate) has a remarkable effect on flotation performance, which can not only effectively activate the refractory copper oxide mineral, but also depress the slime of bauxite and some other impurities, such as cadmium, magnesium and silicon, etc. At last, a copper recovery of 76% with a concentrate grade of 21.65% was achieved from the ore.
