    TheFalcon Concentratoris a Fine Gold Recovery Equipment made of a rotating bowl with the smooth inclined wall. The feed slurry enters the bottom of the bowl and gets stratified along the bowl wall. The heavier material settles on the wall while the lighter particles are pushed to the lip of the bowl and discharged as the overflow

    In the second peak, the gold recovery proceeds mainly by autogenous carrier flotation of the gold fine aggregates (see Fig. 4). The fact that the second peak yields higher flotation rates, recoveries (66%) and grades (80 g/t Au) compared to the first one is L. Valderrama, J. Rubio/Int. J. M iner

    Feb 15, 2019· The excessive coarse size fraction of −100 + 74 μm and the fine size fraction of −20 μm were considered to be detrimental to the recovery of gold in the process of separation flotation. Lower gold recovery of the coarse size fraction may be attributed to insufficient liberation of gold from the sulfide minerals (e.g. galena) and the increased probability of particle/bubble detachment during the …

    Nov 21, 2018· Bubbles containing gold and other hydrophilic minerals accumulate at the top of the water level as froth. This froth is then scraped off to create a concentrate of gold and other hydrophilic minerals. Flotation creates high quality concentrates and is good at capturing fine gold.
