Flotation is a physico-chemical separation process that utilises the difference in surface properties of the valuable minerals and the unwanted gangue minerals. The theory of froth flotation is complex, involving three phases (solids, water, and froth) with many subprocesses and interactions, and is not completely understood.
Get priceCollectors, some of the most important flotation reagents used in the flotation process, are used to modify the surface properties of minerals. A collector is a chemical that selectively binds to the surface of target minerals and imparts hydrophobicity to those mineral particles, a necessary condition for air bubble attachment.
