Flotation of Gold and Gold-Bearing Ores - ScienceDirect

2016-1-1  Gold hydrophobicity is enhanced by the addition of flotation collectors, and no flotation plant relies solely on the natural floatability of gold for its recovery. Naturally occurring or free (liberated) gold is optimally recovered in a flotation circuit at natural or near-natural pulp pH values and with the addition of small amounts of collector.

Flotation of Gold and Gold-Bearing Ores - ScienceDirect

2016-1-1  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).

Flotation Froth - an overview ScienceDirect Topics

Froth flotation is a process that selectively separates materials based upon whether they are water repelling (hydrophobic) or have an affinity for water (hydrophilic). Importantly, the word flotation is also used in the literature to describe the process in density separation in which lighter microplastics float to the surface of a salt solution.
