Experimental Study on High-efficiency Flotation Recovery of Refractory Copper oxide Ore in Tibet
In this experiment,ammonium sulfate and sodium sulphide were used as sulfides first,and then ammonium butyrate black powder and ethyl thiocarbamate combined collector was used to eliminate the adverse effects of slime,the recovery effect of copper oxide of fine particle and rich intergrowth can be improved greatly.Adopt a thick one roughing-three cleaning-three-scavenging closed-circuit process,The recovery of copper reached 81.04%and the copper grade was 20.31%.
