  • Froth Flotation and Gold Extraction Manhattan Gold &

    23-07-2014· First, refractory gold ore is ground as finely as possible usually so the individual grains are much less that 100 micrometers. The ground up ore is mixed with water to create a slurry, which is mixed with surfactants to increase the gold’s hydrophobicity. This mixture is placed into a tank or flotation cell filled with distilled water.

    Gold Flotation 911 Metallurgist

    13-07-2016· Finely divided metallic gold in milling ores floats readily, and a high-grade concentrate can be made by flotation if no interfering slime or gangue is present. Any good collector may be used for the flotation of gold, but organic collectors of the xanthate type produce a cleaner, higher grade concentrate than coal tar-cresote oils.
