Froth flotation is a method for separating hydrophobic materials from hydrophilic materials . Since its discovery, froth flotation has been a major component for the processing of sulfide rich ores, including copper, coal, and refractory gold.
Imhof et al. detailed the use of pneumatic flotation cells to treat a magnetic separation stream of a magnetite ore by reverse flotation to reduce the silica content of the concentrate to below 1.5%. From laboratory testing, they claimed that the pneumatic cells performed better than either conventional mechanical cells or column cells.
The discharge from the tube mill is first passed through a 4 mesh screen to separate out coarse material, which is laundered direct to the classifier. The remainder of the pulp, diluted to give a W/S ratio of 1/1, passes to a Denver Sub A Flotation Cell, from which 60% of the gold and silver in the feed is removed as a concentrate.
fact that some forms of gold such as free gold do not break apart during conventional grinding, coarse gold can accumulate in the circulating load, and eventually be lost. eriez has developed a flotation cell that uses fluidized water to enhance flotation of coarse particles. More than 40 units have been
Tailing from the cell flows to the classifiers, and the flotation concentrate joins the concentrate stream from .the main flotation circuit. The purpose of the hydraulic attachment is to remove gold that is too coarse to float, thus avoiding an accumulation in the tube mill circuit. The cones have increased recovery from 60 to 75 per cent.
