The copper ore slurry from the grinding mills is mixed with milk of lime to give a basic pH, pine oil to make bubbles, an alcohol to strengthen the bubbles, and a collector chemical called potassium amyl xanthate .
Tube mill. Tube mills are used for wet grinding iron ore, gold/copper ore, nickel ore and other ores, as well as for grinding lime/limestone for flue gas desulphurisation systems, coal and other raw materials. Depending on the required product quality, wet grinding tube mills operate in either open or closed circuit.
16/05/2016· The normal practice is to put lime into the primary ball mills and to add xanthates at the last possible moment before flotation, while aerofloat and di thio phosphates are preferably introduced at some point in the grinding circuit, since they generally need an appreciable time of contact as compared with xanthates.
21/05/2017· The attraction of semi autogenous grinding in copper operations is that they can accommodate ores that are hard or soft, wet or dry, sticky or otherwise. The SAG mill can handle everything that is presented to it, regardless of coarseness or fineness, or hardness or moisture content, and from it prepare satisfactory feed for subsequent secondary grinding by
