Effects of Some Metal Cations on the Flotation of Chalcopyrite and Galena
Effects due to some metal cations, such as Ca2+, Mg2+,Fe2+, Fe3+, Cu+, Cu2+, Zn2+ and Al3+ etc.,which are produced in the pulp when the complicated ore is dipped in the deioned water, on the flotation of chalcopyrite and galena with the isopropyl thionocarbamate as collector have been studied.It is found that chalcopyrite floatability is not influenced by these cations, and the cations can be divided into three types according to their effects on the purified galenas floatahility with the same conditions, as activator such as Cu+; as depressant such as Al3+, Fe3+, Fe2+, Zn2+ and Cu2+ , unaffecfive such as Mg2+ and Ca2+.
