Sulphide Gold Ore Treatment by Leaching and Flotation Process

Problem with gold recovery from sulphide ore: How may a mill get the maximum recovery of gold from a sulphide ore, at the least capital cost and at the same time obtain the highest net return. This latter point is most important. In many cases a gold mill using an all-cyanide flowsheet with fine grinding of all the ore will report very low gold content in the tailings particularly on an

Flotation of Gold and Gold-Bearing Ores ScienceDirect

01/01/2016 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, followed by the installation of pyrite flotation plants on numerous gold mines in South Africa.

Froth flotation Wikipedia

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.

The High Mud Content of The Raw Ore Affects The Flotation

Flotation separation is one of the commonly used processing methods in gold ore processing plants. However, in the gold ore flotation process, part of the raw ore has a large mud content, which affects the flotation effect, and may even affect the crushing and concentrate filtering effect. It is recommended to conduct a processing test before determining the process flow and process parameters.
