Flotation of gold and gold-bearing ores

2005-1-1 · 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).

2021-3-19 · 2. Following copper flotation, pyrite is recovered as a flotation concentrate which is then leached with cyanide in a CIL (carbon in leach) circuit. Pyrite in the copper rougher tails is recovered using sodium sulfide (Na 2 S) as an activator and potassium amyl xanthate (PAX) as a collector. Some mine areas contain high levels of clay. High

Xanthate

R. Dunne, in Gold Ore Processing (Second Edition), 2016 3.2 Flotation Collectors for Gold and Gold Carriers. Flotation with xanthate collectors involves the anodic oxidation of the collector that may involve subprocesses such as metal xanthate formation, chemisorption of the xanthate ion, and oxidation of the xanthate to form dixanthogen (Groot, 1987; Monte et al., 1997).

New Eco-Friendly Xanthate-Based Flotation Agents

An optimal laboratory two-step procedure was developed for sodium/potassium O-alkyl carbonodithioate (sodium/potassium alkyl xanthates) production in the form of aqueous solutions. Sodium isopropyl xanthate (Na-iPrX), as the most effective salt in a real ore flotation process, was also produced at an industrial level and introduced as a collector for copper ores.
