The Introduction of Flotation Frothers

Flotation frothers, also known as flotation foaming agent, is an essential flotation agent for froth flotation. The role of flotation frothers is mainly to produce a large amount of foam in the pulp, so that the available minerals are effectively enriched at the interface between air and water to create the conditions required for flotation process.The quality of flotation frothers directly
