METHOD FOR CONTROL OF FLOTATION PROCESS Russian patent published in 1998 - IPC

Abstract RU 2109575 C1

FIELD: ferrous metallurgy, in particular, ore concentration by flotation; may be used in processing of copper, copper-nickel, lead-zinc, copper-zinc and complex ores. SUBSTANCE: method includes measurement of difference of potentials of platinum electrode and glass - oxidizing electrode and variation of consumption of xantogenate or some other sulfhydryl collector depending on measured difference of potentials. In separation of copper-nickel concentrate, the value of potential difference is maintained such as to have maximum difference in flotation rate of pentlandite and pyrrhotine. EFFECT: higher efficiency. 2 cl, 1 dwg , 4 tbl
