Where Does Nickel Come From? Nickel is the fifth most abundant element in the Earth, but most of that nickel is located in the core, more than 1,800 miles below the surface.In Earth's crust, two major types of ore deposits supply most of the nickel used today: magmatic sulfide deposits (such as the pentlandite and pyrrhotite deposits found at Norilsk, Russia; Sudbury, Ontario, Canada; and ...

Primary abundance variations of nickel, copper, and platinum group elements in magmatic-sulfide ore are controlled by the composition of the silicate magma and the mass ratio of silicate to sulfide liquid (Naldrett, 1989). In addition to sulfur, iron, nickel, copper, cobalt, and the platinum group elements (platinum, palladium, rhodium, ruthenium,
ROASTING OF SULFIDE MINERALS In addition to common metals like copper, lead, zinc, and nickel a number of other metals such as antimony, bismuth, cadmium, cobalt, mercury, and molybdenum occur as sulfide minerals. Sulfides are not reduced with the most widely used redu-cing agents, carbon and hydrogen, because the free energy change for the ...
A method of concentrating nickel sulfide ores by flotation which comprises subjecting the ore in the form of a pulp to a flotation process in the presence of an effective quantity of a flotation collector comprising a dithiocarbamate compound corresponding to the formula ##SPC1## Wherein X is oxygen or sulfur and R is hydrogen or a hydrocarbon radical containing from 1 to 10 carbon atoms; R 1 ...
Nickel Sulfide Ores and Impact Melts: Origin of the Sudbury Igneous Complex presents a current state of understanding on the geology and ore deposits of the Sudbury Igneous Complex in Ontario, Canada. As the first complete reference on the subject, this book explores the linkage between the processes of meteorite impact, melt sheet formation, differentiation, sulfide immiscibility and metal ...
Low-grade sulphide ore is mined from Mt. Keith, a large open-pit operation, while high-grade nickel sulphide ore is mined at the Cliffs and Leinster …
Nickel sulfide ores can be classified in terms of the rock types with which they are associated and the tectonic setting into which these rocks were emplaced. Certain combinations of rock type and tectonic setting have proved to be particularly productive. These are (1) noritic rocks intruding an astrobleme (Sudbury); (2) intrusions feeding ...
The nickel-sulfide ore from the Mt. Keith plant (Western Australia) was used for the tests. It is a low-grade nickel sulfide ore which is characterized by complex mineralogical composition with a large content of serpentine minerals. The experimental program included agglomerate flotation tests …
Nickel Sulfide Ores by Pressed Powder Method on Simultix14 Introduction Nickel is one of the essential base metals in modern industries. About 60% of nickel is used to make stainless steel. In the recent years, market price of nickel metal and volume of primary nickel production and ore production have been increasing. Therefore,
Metallic sulfide mining (aka hard rock mining) is the practice of extracting metals such as nickel, gold and copper from a sulfide-rich ore body. Sulfides are a geologic byproduct of mining in this area, and by exposing sulfides to the air and water in our atmosphere, sulfuric acid can be created — threatening to poison the nearby water ...

Sulfation roasting, a common activation technique, is a potential method for cleaner production of nickel from complex low-grade ores. In this study, nickel oxide–sulfide mixed ore concentrate ...
At present, sulfide nickel deposits are the primary source of mined nickel. Sulfide ore grades range from 0.15-8% Ni, with 93% of known deposits ranging from 0.2-2% Ni. All nickel ores have relatively low nickel content, the classification is as follows: high-grade nickel ore has Ni content greater than 1.8%, middle-grade nickel ore has Ni ...
magmatic sulfide deposits where the principal ore mineral is pentlandite [(Ni,Fe) 9 S 8]. The ionic radius of divalent nickel is close to that of divalent iron and magnesium, allowing the three elements to substitute for one another in the crystal lattices of some silicates and oxides.

Thus the original source of most of the nickel ore bodies found in North America and elsewhere in the world was probably the mantle. TYPES OF DEPOSITS All the significant types of nickel ore deposits are represented in North America. Sulfide deposits are by far the most important source of nickel, both quantitatively and numerically.
• KEY IDEA: Most nickel sulphide deposits have been overprinted bysignificant post-ore deformation and alteration which can be very significant economically. – Deformation can mechanicall y remobilize sulphide-rich ores; tenor variations may occur related to hydrothermal redistribution of metal and addition of sulphur.
Nickel is commonly present in two principal ore types – sulfide or laterite ores. Sulfide ores are typically derived from volcanic or hydrothermal processes and usually include copper (Cu) and/or cobalt, and sometimes other precious metals such as gold or platinum and palladium (generally grouped as platinum group metals or PGMs).
Nickel is most widely used in the production of stainless steel. Traditionally, nickel has been processed from sulfide ores in an approach similar to copper processing, in which the ore is upgraded to concentrates and then smelted. As sulfide ore resources dwindle, however, processing of lateritic nickel ores is becoming of greater necessity ...
Nickel-copper sulfide ore deposits are found at the base of mafic and ultramafic bodies. All their host rocks, except the Sudbury Igneous Complex, are thought to be mantle derived melts. The Sudbury Igneous Complex is thought to be the product of complete melting of continental crust. In the case of mantle-derived magmas, a high degree of partial melting of the mantle serves to enrich the ...
Nickel-Cu sulfide ore deposits can occur as single or multiple sulfide lenses within mafic and/or ultramafic bodies with clusters of such deposits comprising a district or mining camp. Typically, deposits contain ore grades of between 0.5 and 3 percent Ni and between 0.2 and 2 percent Cu.
laterite ores imported mainly from New Caledonia, the Philippines and Indonesia. In Tasmania, the Avebury nickel sulfide mine near Zeehan operated for two years up to 2009 after its discovery in 1997. Nickel sulfide operations In the decade up to the early 1990s, annual production from nickel sulfide deposits ranged mostly between
Sulfide ores are mostly smelted by matte-making. Different pyrometallurgical processes are used to produce low-nickel matte from various nickel sulfide ores. Then low-nickel matte is converted into high matte, i.e. sulfide and copper sulfide alloys. High matte is then refined by different methods in a refinery to produce different nickel products.
