FLOTATION of GOLD

fundamental work on the Sotation of gold-bearing ores. In spite of the lack of basic research on Sotation of gold-bearingores, the Sotation technique is used, not only for upgrading of low grade gold ore for further treatment, but also for beneRciation and separation of difRcult-to-treat (refractory) gold ores. Flotation is

Flotation of Gold and Gold-Bearing Ores ScienceDirect

Jan 01, 2016· 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).

Optimisation of gold recovery by selective gold flotation

Gold flotation is often overlooked as a processing option as the precious metal is viewed as being associated with the sulphide particles present in the ore, even when a proportion of the gold is free. Gold does float readily, however, and the free gold can be selectively floated away from an ore

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 pre-enrichment process for refractory ores.

What Are Commonly Used Gold Recovery Chemicals? CNFREE

In order to extract gold, it is necessary to crush and grind the ore to suitable size and then separate the gold from the ore using specific mineral processing method and gold recovery chemicals. At present, gravity separation, flotation separation, heap leaching and cyanidation (CIL,CIP) are four commonly used gold recovery methods.
