DetailsInitial results were very encouraging. Overall mill gold recovery increased approximately 5%. Typical plant test flash flotation metallurgical results were: FI believes the addition of flash flotation to the grinding circuit has decreased future conventional flotation cell volume requirements for future expansions.
DetailsColumn flotation cells, like mechanical cells, are used to perform mineral separations. Column cells do not use mechanical agitation (impellers). Instead, mixing is achieved by the turbulence provided by the rising bubbles. Columns are mostly used to produce final grade concentrates because they are capable of high selectivity.
DetailsFirst, 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 gold's hydrophobicity. This mixture is placed into a tank or flotation cell filled with distilled water.
