CHAPTER 7 FLOTATION OF SULPHIDE MINERALS

Selective flotation. Pb-Zn bulk flotation. Sulphide minerals are floated by sulphydryl collectors (thio-componds) Adsorption of Sulphydryl Collectors: Adsorption of sulphydryl collectors may occur mainly by chemisorption at metal ion sites on a surface, and by electrochemical mechanisms. Also physisorption may occur by van der

Sulphide Gold Ore Treatment by Leaching and Flotation Process

Problem with gold recovery from sulphide ore: How may a mill get the maximum recovery of gold from a sulphide ore, at the least capital cost and at the same time obtain the highest net return. This latter point is most important. In many cases a gold mill using an all-cyanide flowsheet with fine grinding of all the ore will report very low gold content in the tailings particularly on an

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

Mining Industry Copper Sulfide Ore and Flotation Process

1 Types of copper sulfide ore (1) Single copper mineral Its ore characteristic is relatively simple, and the only useful component that can be recycled is copper. The gangue minerals are mainly quartz, carbonate and silicate. (2) Copper-sulfur ore Called copper-bearing pyrite. In addition to copper minerals, iron sulfide can be recovered, and the main mineral of sulfur is pyrite.
