09/07/2019  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.

Treatment of Mixed Sulfide Oxide Ores of Copper

18/03/2017  Many of our largest copper deposits contain both sulfide and oxidized copper minerals. The large porphyry mines, with a total copper content of from 1.3 to 2.0 per cent., send to their mills ore with an oxide content of from 0.2 to 0.4 per cent. While the recoveries of the sulfide

Estimated Water Requirements for the Conventional ...

Copper sulfide ores must be concentrated before they can be economically transported to a smelter. Froth flotation is part of a copper beneficiation process in which finely ground ore is placed in aerated tanks that contain a water-based solution from which a copper-sulfide-rich froth is recovered through the use of a combination of physical and chemical interactions. The remaining non-ore ...

If sulfide minerals are present in these rocks, especially pyrite, the sulfides can oxidize and cause acid rock drainage. Acid seepage from tailings. Tailings produced from the milling of sulfide ores — primarily copper, lead, and zinc ores — may have

Sulphide Gold Ore Treatment by Leaching and Flotation

11/01/2018  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

Gold Recovery And How To Choose The Right Process ...

Gold ore is considered free-milling when it is easily liberated by grinding and separated from the other minerals. A more technical definition is that you are able to recover over 90% of the gold by a conventional gravity-cyanidation process with low reagent consumption . Free-milling

Main Copper Sulphide Extraction Process Mining Pedia

The foaming agent of copper sulfide ore mainly includes terpenic oil and methyl isobutyl methyl alcohol. The pH regulator is mainly lime. When the content of pyrite is small, the PH of the slurry is controlled by 7~9. When the content of pyrite is large, the PH of the slurry is controlled above 11-12. When silt content is large in the ore, a proper amount of water glass or CMC is needed to ...
