Disintegration processes applied at the initial stage of beneficiation allow extraction of the valuable components in a more economical and environmentally friendly way and thus increase the profitability of ores and deposits [3-5]. The complexity of finely disseminated sulphide ores processing is caused by the difficulty of opening of clusters ...

Sulphide ores are a major source of Cu, Ni and precious metals. A basic principle of the extraction processes is to blow air into the molten sulphide in order to oxidise (1) S, which forms a gas and (2) Fe, which forms predominantly FeO and then partitions to a slag phase which covers the matte. A key element in the recovery of the metals is the solidification of …

Sulphide ores Similar graphs can be plotted for the reduction of any metal oxide and also for the reduction of chloride and sulphide ores. The principal ore of lead is galena, PbS. Although there are some galena deposits in Great Britain, much of this country s requirements must be imported.In the extraction of lead, the sulphide ore is first roasted …

Apr 11, 2022· The ore types of copper-nickel sulfide ore are mainly magmatic-melted copper-nickel ore. When the nickel content is more than 3 %, it is rich and can be directly smelted. When the nickel content is less than 3 %, it needs beneficiation treatment. When the nickel ore content is less than 3 %, it is mainly accompanied by a large number of …

Jun 01, 2007· Sulphide Ni–Cu deposits occur typically in mafic and ultramafic igneous rocks and intrusions. The occurrence of minerals affects the separation efficiency of the sulphides. Coarse grained ores are often relatively easy to process, but some ores have altered in metamorphosis. Disseminated secondary minerals often require fine grinding …
