froth flotation of gold ores

4 Types of Gold Ore Froth Flotation Combined Process

For vein gold ore with high arsenic and sulfur or high carbon argillaceous, the gold sulfide concentrate can be obtained by the froth flotation, and then the flotation concentrate can be recovered by the thiourea leaching process. Thiourea gold extraction is a kind of increasingly sophisticated gold extraction method with low toxicity.

Froth Flotation Method JXSC Machine

The froth flotation method is widely used to treat various veins of gold and silver ores for the following reasons: (1) In most cases, the froth flotation process can enrich gold and silver in sulfide concentrate to the greatest extent and discard a large number of tailings, thus reducing the smelting cost.

Recovering Gold through the Froth Flotation Process

Feb 06, 2018· Froth flotation works by exploiting the hydrophobic properties of gold molecules. First, ore is ground into an extremely fine powder. The powdered ore is mixed with water to create a slurry, which is mixed with surfactants to increase the gold’s hydrophobicity. This mixture is placed into a large tank filled with distilled water.

Froth flotation ore dressing Britannica

Flotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic condition—that is, the surfaces are either repelled or attracted by water. The flotation process was developed on a commercial scale early in the 20th century to remove very fine mineral

R. Dunne, in Gold Ore Processing (Second Edition), 2016. 7.2 Flotation of Telluride Minerals. The information available shows that gold tellurides are easily floated, and in practice only a frother at a pH value of around 7–9 is required (Smith, 1963; Singh, 1956; Colbert, 1980; Yan and Hariyasa, 1997), while the addition of small amount of copper sulfate may be beneficial.
