Dec 20, 2018 · Gold flotation. The Froth Flotation Method is means separating minerals according to their different physical and chemical properties. According to classification, the flotability of gold and silver minerals is included in the first category of natural and non-ferrous heavy metal sulfides, characterized by low surface wettability and easy flotation, which can be flotation by xanthate collectors.
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, maintenance, and depreciation costs.
Gold and Silver Processing | Eriez Flotation Division
APPLICATION: GOLD AND SILVER PROCESSING. EFD has a number of industry-leading flotation products for processing gold. This includes the HydroFloat, a state-of-the art flotation unit that uses fluidization to selectively float coarse and high SG gold particles that cannot normally be concentrated using flotation.
A review of the flotation of native gold and electrum
Review of flotation of native gold and electrum 953 Pre-flotation treatment Pre-flotation treatment includes grinding to liberate the native gold, which is considered earlier, classification into slime and granular fractions for separate treatment, which is practised in several plants, and conditioning with appropriate reagents as discussed here.
1 · relative SG of gold, and the 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.

Gold Flotation - Mineral Processing amp; Metallurgy
It is a good practice to recover as much of the gold and silver as possible in the grinding circuit by amalgamation, corduroy strakes, or other gravity means to prevent their accumulation in the classifier; otherwise gold that is too coarse to float may escape from the grinding section into the flotation circuit where it will pass into the tailing and be lost.
