the flotation gold extraction process is commonly used to process gold-bearing sulfide ore with high floatability, because the flotation process
froth flotation works by exploiting the hydrophobic properties of gold molecules. first, ore is ground into an extremely fine powder. the the froth is removed from the top of the cell creating concentrated gold, while the flotation tailings at the bottom of the tank are disposed of
thus, gold fines recovery proceeds through carrier and/or autogenous carrier flotation. differences in response are mainly due to the residence time of particle
lime (calcium oxide or calcium hydroxide) is arguably the most common reagent used in the extractive minerals processing industry. as an effective and economic

application of flotation to gold ore. a flotation plant is being erected at the falcon mine, rhodesia, to treat ore containing gold and copper.
while earlier concentration methods, such as gravity followed by cyanidation, were effective in processing gold ore, flotation opened the minerals market. metal.

the first gold flotation testing should be confined to an all-flotation method so that the experimenter can become familiar with the ore.
