Apr 04, 2018· Suitable nickel supply can be found from two sources: nickel sulfide deposits and nickel limonite deposits, the latter being a type of laterite. Nickel sulfide deposits, such as those exploited by PJSC Norilsk Nickel Co. and in Voisey's Bay and Ontario Division, are exploited using open pit or underground mining.
The technology is useful but is also a serious source of air pollution. Roasting consists of thermal gas–solid reactions, which can include oxidation, reduction, chlorination, sulfation, and pyrohydrolysis. In roasting, the ore or ore concentrate is treated with very hot air. This process is generally applied to sulfide minerals.

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.
• Stage 1 Leaching: A finely-ground, highgrade nickel sulphide concentrate slurry is pumped into- an autoclave, at relatively low temperature and pressure, where oxygen injection is used to partially oxidise the sulphide concentrate into soluble metal sulphate species (nickel, cobalt, copper, iron etc), sulphuric acid and sulphur.

electronics and nickel is used to produce stainless steel and nickel batteries (like those being used in electric cars). 7 Sulfide mining is remarkable in its mineral to waste ratio. The USGS reported that the average yield of copper mining was between 0.47 and 0.60 percent 8 and that production
Nickel is recovered through extractive metallurgy: it is extracted from its ores by conventional roasting and reduction processes that yield a metal of greater than 75% purity. In many stainless steel applications, 75% pure nickel can be used without further purification, depending on .
Dumont Nickel Project is a nickel sulphide (NiS) deposit lying in the Abitibi-Témiscamingue region of Quebec, Canada.

Dec 06, 2013· Sulfide Mining in Northeastern Minnesota Far and away, Metallic Sulfide Mining represents the greatest current threat to the BWCAW and its environs. The extraction of heavy metals – gold, copper, palladium, nickel and others – from sulfide bearing o re has the potential to contaminate waters flowing into the Wilderness.
But although not as extensive as these nickel sources, North America too is blessed with an abundance of the white metal. Canada, in fact, is one of the top five nickel sulphide sites globally. Its deposits may not be covered regularly by mining news outfits, yet they do exist, and exploration and mining activities around them are quite lively.
