Jul 23, 2014018332In 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. The ground up ore is mixed with water to create a slurry, which is mixed with surfactants to increase the.
