flotation of gold associated with pyrite

Selective flotation of pyrite and gold tellurides

Mar 01, 1997· Thus, when gold occurs in the form of gold-tellurides with pyrite, which also contains a significant amount of gold, the study of the selective flotation of gold tellurides from pyrite becomes more important. To investigate the flotation behaviour of gold tellurides in comparison to pyrite, a series of experiments were carried out.

Gold-Pyrite ores

to depress gold flotation, a balance must be maintained between good base metal metallurgy and gold recoveries. Natural pH is recommended for gold flotation. Alternatively using soda ash for pH adjustment can reduce gold depression. Where gold is associated with pyrite in base metal ores where iron sulphides are depressed and report to the

Rcovery of gold in pyritic ores Mine Engineer.Com

The pyrite in which small amounts of gold occurs is of crystalline variety (primary pyrite). The characteristics of primary pyrite are a absence of porosity, an extreme brittleness, a resistance to oxidation, and the existence of gold possessing a weak susceptibility to magnetism (due to a fine coating of a iron compound).

The role of sodium sulfide in the flotation of pyrite

Apr 01, 2018· In copper-gold flotation plants, pyrite which is depressed in copper flotation is often floated subsequently with the addition of sodium sulfide (Na 2 S) to recover the associated gold. For the first time, this study investigated the role of Na 2 S responsible for the flotation of pyrite depressed in chalcopyrite flotation through flotation tests and Cyro-XPS (X-ray photoelectron spectroscopy

Cyanide chemistry and its effect on mineral flotation

Nov 01, 2014· Gold associated with pyrite in Witwatersrand gold ores occurs mainly as minute inclusions and veinlets (a few microns in size) locked in the pyrite matrix (Anhaeusser et al., 1987). In general the flotation of gold associated with sulphides follows the same trend as the flotation of these sulphide minerals which are greatly affected by cyanide

Flotation Reagent an overview ScienceDirect Topics

The Morro Velho mine located at Raposos treats graphitic gold ores that contain free gold and gold associated with pyrite. The first stage of flotation to remove free gold and graphite is accomplished with MBT at neutral pH. The remaining gold-containing pyrite is floated in a second stage with the addition of dithiophosphate.

The effect of zinc cyanide on the flotation of gold from

Jan 01, 2016· In the ore, 13.4% of the gold in the flotation concentrate in the absence of cyanide is associated with sulfide minerals, mainly auriferous pyrite (Guo et al., 2015). Clearly, the auriferous pyrite was depressed by free cyanide, while the flotation of liberated gold (free gold) was not
