3 Nickel Sulphide Resources1 Nickel resources are typically classified as sulphides or laterites. Approximately 73% of the world's nickel resources are estimated to be contained in laterites while 27% are as classified as sulphide. Currently, some 37% of the world's nickel supply is derived from sulphide resources and almost all
Nickel processing - Nickel processing - Extraction and refining: The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used. The major differences in equipment are the use of higher-temperature refractories and the increased cooling required to accommodate the higher operating temperatures in nickel ...

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.
Nickel sulfide ores associated with komatiites in Archean greenstone belts are the most important examples of mag- matic mineralization in volcanic rocks. They contain about 25 percent of the world total identified nickel resource in deposits with ≥0.8 percent Ni, as well as significant amounts of copper and platinum-group elements (PGE).

The present invention is a process to recover precious metals from sulfide ores. It involves chlorinating a mixture of an ore concentrate and salt to form a liquid melt. The salt preferably contains potassium chloride. This chlorination is carried out at a temperature between 300° and 600° C. while stirring. The process converts precious metals in the elemental and sulfide forms into ...
There are widespread nickel resources around the world, but divided principally between nickel sulfide or laterite (oxide) resources. Historically production has been dominated by sulfide ores but ...
Nickel ore mainly consists of copper-nickel sulfide ore and nickel oxide ore, beneficiation and processing of both methods is completely different. Copper-nickel sulfide ore beneficiation methods: The most important is the flotation. The magnetic and the gravity separation is usually secondary dressing method. Flotation copper sulfide nickel ...
In hydrometallurgical processes, nickel sulfide ores undergo flotation (differential flotation if Ni/Fe ratio is too low) and then smelted. After producing the nickel matte, further processing is done via the Sherritt-Gordon process. First, copper is removed by adding hydrogen sulfide, leaving a concentrate of only cobalt and nickel.

1.1.2 Extraction of Nickel and Cobalt from Sulphide Ores. Sulphide ores were mostly created by (i) the intrusion of molten magma from the mantle into the crust of the earth and (ii) the formation of localized metal-rich sulphide ore bodies by sequential solidification and/or hydrothermal leaching and precipitation.
Kupfer nickel is less abundant but richer than the preceding, and occurs in veinlets, especially in Scotland and Saxony. The percentage of nickel varies from 20 to 30. Arseno-sulphide or grey nickel is met with more particularly in the Harz, Sweden, and Styria. The percentage of grey nickel, corresponding to the formula Ni2AsS2, is 35-48.
All primary sulfide ores of copper sulfides, and most concentrates of secondary copper sulfides (being chalcocite), are subjected to smelting.Some vat leach or pressure leach processes exist to solubilise chalcocite concentrates and produce copper cathode from the resulting leachate solution, but this is a minor part of the market.. Carbonate concentrates are a relatively minor product ...
The smelter for sulfide ores produces sulfur dioxide gas. This is scrubbed from the flue gases to make sulfuric acid for leaching copper from oxide ores. Scrubbing sulfur dioxide also protects the environment. For example: FeO(s) + SiO 2 (s)→ FeO.SiO 2 (slag) This is .
Matte, crude mixture of molten sulfides formed as an intermediate product of the smelting of sulfide ores of metals, especially copper, nickel, and lead.Instead of being smelted directly to metal, copper ores are usually smelted to matte, preferably containing 40–45 percent copper along with iron and sulfur, which is then treated by ...
Copper-Nickel ores Pentlandite ((Ni,Fe)S) is the most important nickel sulphide mineral and is often associated with nickel-containing pyrrhotite and chalcopyrite. Gangue minerals can include talc and other troublesome silicates which must be dispersed and/or depressed.
