    Flotation collector is a kind of organic substance that can selectively act on the surface of minerals to make the ore particles hydrophobic, so that the ore can be catched by the foam and float to the surface of ore pulp, thus being collected. Flotation collectors have many kinds, including xanthate, dithiophosphate and so on.

  • Introduction to Mineral Processing cpchem

    A collector is a chemical that attaches to the mineral surface and produces a hydrophobic (water fearing) surface. While certain minerals are naturally hydrophobic and do not require a collector, recovery is often improved when a collector is used. This water repellent film facilitates the attachment of the mineral particle to the air bubble.

    Flotation. By coating the minerals with small amounts of chemicals or oils, finely ground particles of the minerals remain unwetted and will thus adhere to air bubbles. The mineral particles are coated by agitating a pulp of ore, water, and suitable chemicals; the latter bind to the surface of the mineral particles and make them hydrophobic.
