Sulfuric Acid (Flotation Grade)
CAS Number: 7664-93-9
Sulfuric Acid is used in flotation circuits to lower pulp pH, activate mineral surfaces, and prepare reagent solutions. In acid circuit flotation, it activates sulfide minerals such as chalcocite and native copper by removing oxide surface films, improving xanthate adsorption and collector response. It is also used to dissolve and prepare alkaline reagent solutions such as xanthates and frothers in concentrate and tailings processing.
