  • Flotation Collectors Mineral Processing & Metallurgy

    These flotation collectors are naturally attracted to metallic surfaces making them wanting to get away or get out of water. The most common group of flotation collectors are known as Xanthates. They are attracted to the mineral and to the air of the bubble, attaching themselves to both.

  • Introduction to Mineral Processing

    Introduction to Mineral Processing. Collectors Orfom® CO series collectors. 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

  • Mineral processing Wikipedia

    Dewatering is an important process in mineral processing. The purpose of dewatering is to remove water absorbed by the particles which increases the pulp density. This is done for a number of reasons, specifically, to enable ore handling and concentrates to be transported easily, allow further processing to occur and to dispose of the gangue.

  • Froth flotation Wikipedia

  • The Environmental Fate of Flotation Collectors in Mineral

    Organo-sulphur-based collectors (eg xanthates, dithiocarbamates and dithiophosphates) are widely used in the flotation of sulphide minerals. Xanthates (ROC(=S)S–), for example, adsorb strongly at sulphide mineral surfaces, in a reaction that is electrochemically coupled with the reduction of dissolved oxygen. One of the oxygen reduction products, hydrogen peroxide, reacts directly with
