organic reagents in the flotation of minerals

Flotation Reagent Article about Flotation Reagent by The

Flotation Reagent. The introduction of flotation reagents into the liquid phase of the pulp and subsequent adsorption along the liquid gas and solid liquid interfaces create conditions for the selective flotation of specific mineral particles. There are three principal types of flotation reagents collectors, regulating agents, and frothing agents.
