Effect of activator on properties in sulfurous iron ore flotation
Sulfurous iron minerals with recovery value are contained in a lead-zinc tailing in Fujian Province, China. However, the sulfurous iron minerals are depressed by lime in the early lead-zinc flotation, therefore it is necessary to use appropriate activators to improve the floatability of the mineral. The property of flotation can directly reflect the quality of the flotation index.
