Flotation of Gold and Gold-Bearing Ores - ScienceDirect

Most problems in gold ore flotation are not connected with floating metallic gold. The flotation recovery of free gold (throughout the text free gold is synonymous with liberated gold) is largely affected by physical constraints such as the shape and size of the gold particles and the stability of the froth.

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 containing sulphides.

Sulphide Gold Ore Treatment by Leaching and Flotation …

Flotation in a gold concentrator should be considered not only when building a new plant based on results of a thorough ore test but also in an existing plant when: Ore changes in character. Recovery drops due to need for finer grind. Daily tonnage is increased.

Processing technologies for gold-telluride ores

break down the gold-telluride structure and release free gold. The general processing methods are: oxidation, flotation, and leaching. 3.1. Oxidation Generally, gold ores can be classified into two categories: the 'free milling' and 'refractory' ores. Free milling ores are those that require only conventional physical pre-treatment,

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, …
