Jul 13, 2016 Where a high sulphide recovery is demanded, flotation methods are now in general use, but in the days before flotation was known, a large part of the worlds gold was recovered by concentrating the gold-bearing sulphides on tables and smelting or regrinding and amalgamating the product. Though the modern trend is away from the use of tables, because flotation is so much

Mar 01, 1997 Gold recovery is decreased with the addition of copper sulphate at pH 4.7 - 8.0 but is increased at the higher pH of 11.0. The flotation rate of gold is improved at all pHs by the addition of copper sulphate. The maximum improvement occurs at pH 8.0 which does not correspond to the maximum flotation rates of the sulphides or the teUurides.
If additional water is added to dilute the contents of the flotation cell, and the flow rate of water to the concentrate remains the same, the water recovery will be reduced. The downside of diluting flotation banks is the resulting loss of residence time which can have a negative effect on valuable mineral recovery. flotation circuit diagnostics
