Flotation experiment research on a polymetallic sulfide
2021-3-19 of sulfur can be obtained only when the ore’s pyrite content is high. Gold and silver can be recovered from the concentrates of copper, lead, and zinc or from the products of pyrite. The goal of floating pyrite is not to recover sulfur but to improve the recovery of gold and silver when the pyrite content of the ore is low. Flotation separation

2014-6-5 A proper flotation flowsheet was then proposed based on experimental condition and closed-circuit test. The gold concentrate with the gold grade of 25.14 gton −1 and the recovery of 86.94 % is obtained after one rougher, three cleaners, and four scavengers from fine grinding flotation process. Furthermore, the mechanisms of combined activators and combined collectors were studied by thermodynamic calculation, and structure–activity relationship of flotation

2013-12-24 sulfur production in 1991 from 17% in 1971 in the United States [1]. Mineral processing played only a small role in the elemental sulfur industry. When a sulfur ore was selected, a typical method was grinding the sulfur ore to about 28 mesh followed by froth flotation. Flotation concentrates were melted and filtered to produce sulfur products

Sulphide Flotation - an overview ScienceDirect Topics
Although the exact location of arsenic in the pyrite crystal structure is still being debated the general consensus is that arsenic is replacing one of the two sulfur atoms in the sulfur dipole, thus forming AsS 2−. Whatever the mechanism of arsenic incorporation in the pyrite structure, it is certain that with increasing arsenic content, pyrite becomes more readily oxidizable, which in turn affects its floatability.

The role of sodium sulfide in the flotation of pyrite ...
2018-4-1 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 ...

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 ...
