froth flotation and gold extraction - manhattan gold & silver

Jul 23, 2014 · In gold mining, froth flotation is used to separate gold from gangue by utilizing gold’s hydrophobicity. 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
