The G-Cells are operated in closed circuit, with the tails from the second G-Cell reporting to the first G-Cell and the tails from the first cell reporting back to the flotation feed. Each G-Cell gives a two times upgrade; rougher concentrate at 10g/t Au is upgraded to 20g/t Au in the first G-Cell and then further to 40g/t Au in the second G-Cell.
· Flotation Cells are provided with openings in the partition plates for by-passing the pulp from cell to cell without the pulp circulating through each hood feed pipe. In normal operation these partition gates are left closed; however, this arrangement is advantageous when large tonnages are fed to the Flotation Cell.
Froth Flotation and Gold Extraction
· Most methods of water-based gold extraction are dependent on gold''s lack of buoyancy to work. However, froth flotation uses a different property of gold to separate it from ore. Froth flotation is a method for separating hydrophobic materials (which will not mix with water) from hydrophilic materials (which readily mix with water).
· GOLD FLOTATION. The flotation process, which is today so extensively used for the concentration of base-metal sulphide ores and is finding increased use in many other fields. In 1932 flotation plants began to be installed for the treatment of gold and silver ores as a substitute for or in conjunction with cyanidation.
