What is the foaming agent in the coal washing plant?

Flotation reagents generally include collectors, foaming agents and composite reagents. The collector and foaming agent are used in combination. Foaming agent is used to form bubbles with appropriate size, which are stable and not easy to merge, so that clean coal adheres to the bubbles and floats. At present, most foaming agents are alcohols, such as sec-octanol and fusel.
