  • Froth Flotation and Gold Extraction Manhattan Gold amp; Silver

    Jul 23, 20140183;32;Since its discovery, froth flotation has been a major component for the processing of sulfide rich ores, including copper, coal, and refractory gold. In gold mining, froth flotation is used to separate gold from gangue by utilizing golds hydrophobicity. First, refractory gold ore is ground as finely as possible usually so the individual grains are much less that 100 micrometers.

  • 12.3 Primary Copper Smelting

    Mining produces ores with less than 1 percent copper. Concentration is accomplished at the mine sites by crushing, grinding, and flotation purification, resulting in ore with 15 to 35 percent copper. A continuous process called floatation, which uses water, various flotation chemicals, and compressed air, separates the ore into fractions.
