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 acidoxidative hydromet technology was developed to process nickel sulphide concentrates.
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 and percent 8 and that production

Although Minnesota has a long history of iron ore mining, sulfide mining for copper, nickel, and precious metals has never been attempted. Prices for some metals, including copper, reached historic highs in 2011, and some companies have sought to mine Minnesota''s lowgrade sulfide ores.

Just as steel made from Minnesota''s iron ore powered the military to victory during World War II, supporters of coppernickel mining in the state say the industry could help defeat another ...
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.

Sulphide Versus Laterite Deposits. A summary of the key differences between the 2 types of deposits: Mining – Nickel sulphide deposits, which are typically found deep underground, are typically more expensive and difficult to mine in comparison to laterite deposits, which .
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.
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.
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 .
• Stage 1 Leaching: A finelyground, 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.
Cobalt extraction refers to the techniques used to extract cobalt from its ores and other compound ores. Several methods exist for the separation of cobalt from copper and depend on the concentration of cobalt and the exact composition of the used ore
