Process for the separation of copper sulfide from metallic ...

Copper sulfide in the presence or absence of metallic copper contained in a dross obtained from the copper drossing of lead bullion is separated from metallic lead entrained or occluded in the dross by introducing the dross into a vessel other than a reverberatory furnace, usually a kettle, also introducing an alkali metal sulfide, preferably sodium sulfide, into the kettle, and heating the dross and alkali metal sulfide together in the kettle at an elevated temperature not in excess of 1200 ...

Hydromet Technology - Vale

This type of hydrometallurgical process is not entirely new. Many operations, some of them in Canada, have used hydrometallurgical processes for years for extraction of zinc and copper from sulphide concentrates. However, it was not until the 1990s that an acid-oxidative hydromet technology was developed to process nickel sulphide concentrates.

The mixed ore contains oxide, supergene oxide and hypogene sulphide copper species respectively with the greater part of the deposit being made up of sulphide and mixed ores. The oxide ore has a much higher grade than the mixed and sulphide ores but contributes less to the resource ( Broughton et al., 2002 ).

FROTH FLOTATION : RECENT TRENDS Flotation of Sulphide Ores ...

History of Sulphide ore flotation dates back to beginning of 20th century. Sulphide ores are major sources of base metals like Copper, Lead, Zinc, Nickel, Cobalt etc. Beneficiation of these base metal sulphide minerals is predominating through froth flotation technique.

Copper Extraction from Sulfide Ores - Latest Contents

This process is used for the extraction of copper from low grade sulfide ore. In this process, the crushed and ground ore in bulk (about 100,000 tons) is exposed to air and water in big tanks. The air in the presence of water gradually oxidizes copper and iron sulphides to their surphides.
