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. Though the modern trend is away from the use of tables
Feb 06, 2018 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.
Jul 23, 2014 Froth flotation is a method for separating hydrophobic materials (which will not mix with water) from hydrophilic materials (which readily mix with water). Since its discovery, froth flotation has been a major component for the processing of sulfide-rich ores, including copper, coal, and refractory gold. In gold mining, froth flotation is used
Oct 17, 2016 A total recovery of more than 97% of the gold and silver is made by flotation, while the combined flotation-cyanidation process gives an overall extraction of 95%. The installation is much more compact and its capital cost far less than one embodying fine grinding and cyaniding of the whole tonnage, and it can be run with lower operating
