Four Points To Improve Tin Ore Flotation Recovery Rate
During the flotation process of tin minerals, iron ions will destroy the film on the surface of tin minerals, causing the surface of tin minerals to be oxidized, thus making the flotation of tin ores difficult. Copper ions can form water-insoluble copper-tin salts with tin on the surface of tin ore and can inhibit the process of tin flotation ...
