Mechanochemical sulfidization of a mixed oxide-sulphide ...

Mechanochemical sulfidization of a mixed sulfide/oxide copper ore by co-grinding with sulfur and additives including Mg(NO 3) 2 and Fe(NO 3) 3 salts and iron, aluminum and magnesium powders was investigated for the first time. Also, the influence of sulfidization during the wet-milling process was examined on the separation efficiency and recovery of copper in detail.

Copper Flotation. The copper minerals and waste rock are separated at the mill using froth flotation The copper ore slurry from the grinding mills is mixed with milk of lime (simply water and groundup limestone) to give a basic pH, pine oil (yes, it comes from trees a byproduct of paper mills) to make bubbles, an alcohol to strengthen the bubbles, and a collector chemical called potassium amyl ...

Treatment of Mixed Sulfide Oxide Ores of Copper

Process mineralogy research of a mixed copper ore is studied to identify the occurrence mode of copper and to analyze the mineralogical factors influencing the floatation results. The results show that the ore has features of "high-sulfur, high copper", "various copper mineral types", "fine copper mineral granularity" "disorderly copper mineral ...
