Gold Flotation Production Line. Flotation is widely used in gold processing. In China, 80% rock gold is processed by flotation. Flotation process maximizes the enrichment of gold into sulfide minerals. Tin Ore Mining Process. The density of tin ore is larger than the paragenetic mineral, so the mining process of tin ore apply gravity separation.

23/07/2014 · 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 ...
