Flotation of Gold and Gold-Bearing Ores ScienceDirect

2016-1-1  Flotation of Copper–Gold Ores. For the bulk flotation of copper minerals and gold from supergene copper ores, it is normal practice to add a xanthate as the primary collector and dithiophosphate as a secondary collector (Bulatovic, 1997). This combination gives satisfactory results in respect of copper concentrate grade and copper and gold

The flotation of gold bearing ores — A review

The practice of the flotation of pure gold and gold-bearing ores such as tellurides, aurostibite, kerogen, pyrite, pyrrhotite, copper-gold ores and mixed sulphides is reviewed. The factors which influence the choice of collectors, pH and Eh, are discussed as well as the application of differential flotation.

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

FLOTATION of GOLD 911 Metallurgist

2016-7-11  Gold itself is a rare metal and the average grades for low grade deposits vary between 3 and 6 p.p.m. Gold occurs predominantly in its native form in sili-cate veins, alluvial and placer deposits or encap-sulated in sulRdes. Other common occurrences of gold are alloys with copper, tellurium, antimony, selenium, PGMs and silver. In massive

Optimization and mechanism of gold-bearing sulfide

2014-6-5  In order to overcome the difficulty of extracting gold from gold-bearing sulfide ore by cyanide process, flotation was adopted based on mineralogical analysis. Mineralogy shows that gold particles are of superfine structure and mainly enclosed by sulfide ores. Primary gold-bearing sulfide ore is fine-grained pyrite and arsenopyrite. The paper describes the effects of ratios and dosage of
