The effective and environmental separation of chalcopyrite and molybdenite has long presented a challenge in mineral processing due to their similar floatability and close association at room temperature. This study explores the non-toxic 1-thioglycerol (1-TG) as a selective depressant for chalcopyrite–molybdenite flotation separation. An impressive …

(2) All copper minerals containing iron, such as chalcopyrite and bornite, are susceptible to inhibition by cyanide and lime in alkaline media. (3) The xanthate collector is mainly chemically adsorbed with the cation Cu2+, so the surface contains more Cu2+ minerals and has a stronger effect with xanthate.
