Flotation Reagents: Uses and Advantages in Ore Processing
Stibnite, the antimony sulphide mineral, responds much better to flotation after being activated with lead nitrate. The theory generally accepted on activation is that the activating substance, generally a metallic salt, reacts with the mineral surface to form on it a new surface more favorable to the action of a promoter.
