Jul 23, 2014nbsp018332first, 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 golds hydrophobicity. this mixture is placed into a tank or flotation cell filled with distilled water.

Dec 20, 2018nbsp018332the flotation of gold and silver minerals is mostly carried out in alkaline pulp medium, but for some gold-bearing pyrite and pyrrhotite, it is suitable for flotation in weak acid pulp medium. oxygen has an effect on the flotation process of gold-silver sulfide ore oxidized to different degrees.

Gold flotation i. introduction froth flotation is a widely used separating technique for the recovery of cu and au in porphyry copper-gold ores. in these ores, chalcopyrite and gold are the main valuable mineralmetal phases, with pyrite being the key sulphide gangue mineral. however, in these ores gold is mostly associated with pyrite
