Manganese Ore Processing - Mineral Processing & Metallurgy

Types 1 and 2 ores require a prefloat treatment to remove the calcite as a froth. The calcite must be removed ahead of the manganese since if left in the circuit it will float with the manganese, thereby giving a low grade manganese concentrate. Tailings from the calcite prefloat circuit are then further treated by flotation, floating the manganese as a concentrate.
