Flotation Of A High Grade Copper Ore

Copper Flotation - Mineral Processing & Metallurgy

Since a high-grade concentrate is desired in order to keep smelting costs as low as possible, the circuit usually comprises two stages of cleaning. In most plants flotation is carried out in mechanically agitated machines. The problem of the flotation of oxidized copper ores has not yet been solved.
