  • The role of sodium sulfide in the flotation of pyrite

    In coppergold 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 CyroXPS (Xray photoelectron spectroscopy

  • Froth flotation Wikipedia

    Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and wastewater treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

  • Optimization and mechanism of goldbearing sulfide flotation

    In order to overcome the difficulty of extracting gold from goldbearing 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 goldbearing sulfide ore is finegrained pyrite and arsenopyrite.

  • Sulphide Gold Ore Treatment by Leaching and Flotation Process

    There are many arrangements and combinations using flotation in conjunction with treatment of gold ores. The two gold process flowsheets shown, with some variations, are probably the most commonly used.. In Gold Flowsheet No. 1 the ore is ground in water to such a size as to free the minerals sufficiently to produce a tailing by flotation low enough in value that it may be discarded.

  • Sodium sulfide Wikipedia

    Sodium sulfide is the chemical compound with the formula Na 2 S, or more commonly its hydrate Na 2 SܯH 2 O.Both are colorless watersoluble salts that give strongly alkaline solutions. When exposed to moist air, Na 2 S and its hydrates emit hydrogen sulfide, which smells like rotten eggs.Some commercial samples are specified as Na 2 S·xH 2 O, where a weight percentage of Na 2 S is specified.
