Finding gold by flotation cell minerals

Update date: Dec 07

Jul 01, 1994 The flotation of gold bearing ores--a review 84.5 Residence Time Because flotation is often a rate controlled process it is important to optimize the cell residence time. It has been reported that the rate of gold and pyrite flotation is greater from plants treating coarse milled ores than from those treating finer ores or tailings

    Froth flotation of gold is a widely used beneficiation method for treating rock gold ore in gold concentrating plant, which is often used to treat gold ore containing sulfide minerals with high floatability. The froth flotation process can concentrate the gold in sulfide minerals to the maximum extent, and the tailings can be directly discarded

    In the flotation circuit chemicals are added which attach to the gold and silver minerals. By agitating the ore slurry in the presence of air the gold-bearing minerals attach to the air bubbles and float to the top of the flotation cell. The resulting black concentrate is refloated to remove as much waste as possible

    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 world’s gold was recovered by concentrating the gold-bearing sulphides on tables and smelting or regrinding and amalgamating the product.
