  • The role of sodium metabisulphite in depressing pyrite in

    In response to the high pyrite recovery in copper flotation using seawater, this study investigated the role of sodium metabisulphite (MBS), a widely used pyrite depressant, in depressing the flotation of copper-activated pyrite to identify a solution to maximising pyrite rejection.

  • Copper extraction Wikipedia

    Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.

  • Flotation Reagents Mineral Processing & Metallurgy

    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.

  • 60 Centuries of Copper: The Flotation Process

    Only the flotation process mentioned above could make this practicable; and even so, it requires large companies with huge plants, continuous working and immense capital. This explains why, in order to smelt 4 million tons of new copper in 1963, nearly 400 million tons

  • Handbook of Flotation Reagents ScienceDirect

    The bulk copper–lead flotation with depression of zinc followed by copper–lead separation and re-flotation of zinc is the most common practice in the treatment of copper–lead–zinc ores. About 90% of operating plants use this method.

  • Froth Flotation Process Mineral Processing & Metallurgy

    The Froth Flotation Process is about taking advantage of the natural hydrophobicity of liberated (well ground) minerals/metals and making/playing on making them hydrophobic (water-repel) individually to carefully separate them from one another and the slurry they are in. For this purpose we use chemicals/reagents: Frothers (MIBC) is what allows the formation of air bubbles.

  • Froth flotation Wikipedia

    Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, stone 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.

  • Effect of alkalinity of a pulp on selective flotation of

    We study the effect of one of the main parameters of flotation ore-dressing, specifically, alkalinity of the pulp, on the selective flotation of sulfide and oxide minerals of copper from the Udokan deposition ores (Chita oblast). It is found that the optimum values are pH = 9 for sulfide minerals of copper and pH = 10 for the oxide ones. A supply of lime at the stage of pounding and sodium
