1/12/2020· The refractory nature of the gold orebody prompted a relatively new treatment route, adopted by the Lake View and Star mine in 1929, of sulphide flotation followed by roasting of the concentrate before conventional cyanidation and gold recovery. However, the gold recovery was 80 per cent compared to the Kalgoorlie gold mines of 9698 per cent.

Froth Flotation and Gold Extraction Manhattan Gold Silver

Jul 23, 2014· In gold mining, froth flotation is used to separate gold from gangue by utilizing golds hydrophobicity. First, refractory gold ore is ground as finely as possible usually so the individual grains are much less that 100 micrometers. The ground up ore is mixed with water to create a slurry, which is mixed with surfactants to increase the

The ore is ground to a top size that is much coarser than traditional flotation machines can handle (the top size is a function of the ore characteristics and could be as large as 5 mm). Using a combination of a highshear aerator to capture the finest particles, and a fluidized bed to capture the coarse particles, high recoveries can be obtained across the whole size range.

1.3 Flotation and subsequent processes (refractory ore processing) The flotation process is described in detail in chapter 3.3. Native gold, gold tellurides, and sulphides that contain finely disseminated gold can be floated and recovered in a concentrate. In gold metallurgy flotation is often used as a preenrichment process for refractory ores.
