  • Gold Flotation Mineral Processing & Metallurgy

    Lime should not be used because it is a depressor of free gold and inhibits pyrite flotation. Sodium sulphide is often helpful in the flotation of partly oxidized sulphides but must be used with caution because of its depressing action on free gold. Copper sulphate is frequently helpful in accelerating the flotation of pyrite and arsenopyrite.

  • Silver Gold Recovery Flotation Process

    The ores from which silver and gold are recoverable by flotation divide themselves naturally into two general processing classes: ores in which the valuable minerals are those of the base metals, the precious metals being incidental constituents, and ores in which the gold and silver are of primary importance, the base-metal minerals, if present, being of little or no value.

    7.5. Flotation of Copper–Gold Ores. For the bulk flotation of copper minerals and gold from supergene copper ores, it is normal practice to add a xanthate as the primary collector and dithiophosphate as a secondary collector (Bulatovic, 1997). This combination gives satisfactory results in respect of copper concentrate grade and copper and

  • The role of sodium sulfide in the flotation of pyrite

    In copper-gold flotation plants, pyrite which is depressed in copper flotation is often floated subsequently with the addition of sodium sulfide (Na 2 S) to recover the associated gold. For the first time, this study investigated the role of Na 2 S responsible for the flotation of pyrite depressed in chalcopyrite flotation through flotation tests and Cyro-XPS (X-ray photoelectron spectroscopy
