Significant increase in gold recovery using Jameson Cell flotation
Gold losses during flotation often occur within the fines fraction, which has been an ongoing issue that has challenged the gold mining industry. Subsequently, operations will attempt to coarsen up the primary grind to reduce the fine gold (free gold or sulphide gold) generation, resulting from over grinding. Under-grinding can then to lead to gold losses in the coarse …

Recovering Gold through the Froth Flotation Process
Pre-19th century placer mining operations used mercury to dissolve the gold in crushed ore, making it easier to recover. Later innovations include the MacArthur-Forrest Process and borax flux extraction. However, one of the most interesting methods is froth flotation. Froth flotation works by exploiting the hydrophobic properties of gold molecules.
Fine Gold Recovery by Flotation
Mechanical Fine Gold Flotation Cell. Initially our interest arose from a need, in the laboratory, to pre-concentrate a sample prior to analysis, either to enhance the confidence in the analysis or to facilitate morphological characterisation. A Wemeco Fagergren machine with a 2 litre cell was used. Recoveries were somewhat inconsistent but it ...
