WhatsApp: +86 18221755073Smithsonite, the most common zinc oxide minerals, has become a good alternative for zinc extraction. Flotation is the most widely used approach to separating smithsonite from gangue minerals, because of the its low cost, high selectivity and easy operation [8]. Calcite is one of the most common gangue minerals that coexists with smithsonite [9].
