What are the Flotation Reagents for Barite?
In barite flotation, two or more reagents with strong collecting ability and good selectivity are often combined. The most common combination is the combination of fatty acid collectors and alkyl sulfate collectors. When using combination collectors in flotation, the reagents can promote each other and play a synergistic role. ...
