  • Flotation Collectors Mineral Processing & Metallurgy

    For non-sulfide (e.g., oxide) mineral flotation, the range of Flotation Collectors used is again quite variable, depending on the ore type and operating conditions. The hydrocarbon chain length is typically from 12 carbon atoms to 22 carbon atoms. In the case of non-sulfide flotation, the dosages are somewhat higher than in sulfide mineral flotation, with amounts of 0.1 to 1.0 kg/ton being

    Flotation Reagents & Collectors. Froth flotation is the most widely used industrial process for the separation of finely liberated minerals. The process involves the aeration of minerals in water in the presence of flotation reagents which facilitate the attachment of air bubbles to and levitation of select minerals. Once at the surface, the select minerals are supported by a froth layer until

  • 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. It has been described as "the single most important operation used for the

    Flotation Frothers What is the Function of Frothers. The function of frothers in flotation is that of building the froth which serves as the buoyant medium in the separation of the floatable from the non-floatable minerals. Frothers accomplish this by lowering the surface tension of the liquid which in turn permits air rising through the pulp to accumulate at the surface in bubble form.

    for coal cleaning, since coal is naturally hydrophobic and minerals are generally hydrophilic. Because of coal’s hydrophobicity, froth flotation has employed mostly non-polar oil collectors such as kerosene, crude petroleum, fuel oil. and certain coal-tar distillates (Wójcik et al., 1990; Solov'eva and Muklakova, 1995; Petukhov, 1995).

    The volume of froth generated in the flotation machine under standard operating conditions is often referred to as froth power. The froth power is influenced by the type of collector and frother used. Acidic frothers perform well only in acid pH. Typical examples of these reagents are phenols and alkyl-lauryl sulfonates. Basic frothers are represented by pyridine and homologs, recovered as by
