  • Flotation Collectors - Mineral Processing Metallurgy

    What is a Flotation Collector. For industrial sulfide mineral flotation, the xanthates and dithiophosphates are the major classes of Flotation Collectors compounds used, where M+ is either Na+ or K+, and R is a relatively short hydrocarbon chain typically containing two to five carbon atoms. The solubility, pH application range, physical state ...

  • Froth flotation - Wikipedia

    Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

  • Flotation Reagents Collectors ArrMaz

    Collectors, 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.
