Use of cresylic based dithiophosphates does provide some collection of gold particularly in gold silver ore flotation. Alternatively, if there is significant metallic gold association with silver metal, because silver has a reactive surface for collector bonding, collectors for silver indirectly also result in gold recovery. Consequently, gold flotation recovery requires a focus on floating

Flotation of Gold and Gold Bearing Ores ScienceDirect

1. Background. The application of flotation on a reasonable scale within the gold mining industry commenced in the early 1930s following the introduction of water soluble flotation collectors (specifically xanthates and dithiophosphate collectors) that allowed differential flotation of sulfide minerals (Weinig and Carpenter, 1937, Rabone, 1939, Richards and Locke, 1940, Taggart, 1945).

Froth flotation

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

Gold mineral flotation normally adopts one stage grinding flotation process, but stages grinding and flotation for ore with uneven distribution. Grinding fineness of gold For the gold wrapped in sulfide minerals, sulfide ore reaches monomer dissociation but for the gold with gangue, grinding fineness should reach gold monomer dissociation.

Gold extraction

Froth flotation is usually applied when the gold present in an ore is closely associated with sulfide minerals such as pyrite, chalcopyrite or arsenopyrite, and when such sulfides are present in large quantities in the ore. In this case, concentration of the sulfides results in concentration of gold values.

23/07/2014018332Froth Flotation and Gold Extraction. July 23, 2014. Most methods of water based gold extraction are dependent on golds 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). Since
