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,

Flotation of gold and gold-bearing ores - ScienceDirect

2005-1-1  The flotation characteristics of gold or gold minerals found in refractory sulfide and copper ores have not been described in detail in the literature. The sparse distribution of discrete gold minerals and particles, as well as their exceedingly low concentration in ores, are the principal reasons for the lack of fundamental work on gold ...

Optimisation of gold recovery by selective gold flotation ...

2001-2-1  GOLD FLOTATION Collectors The use of charged water soluble collectors such as xanthates and dithiophosphates slow down the rate of flotation of naturally floatable minerals, including native gold, at lower concentrations (Klimpel, 1997). Only the larger chained carbon groups (amyl and butyl) appear to be good gold flotation reagents.
