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. Then ...
Nickel sulfate powder made from nickel sulfide ore, is a crucial ingredient in cathode formulation for lithium-ion batteries needed to propel electric vehicles. Nickel is popular with EV battery-makers because it provides the energy density that gives the battery its power and range.
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.
The Norseman–Wiluna Greenstone Belt, within which Black Swan is located (Fig. 1), is one of the world's major nickel provinces.It hosts in excess of 1.5 billion tonnes of sulfide ore containing over 11 million tonnes of nickel metal, in addition to nearly 18 million tonnes of potentially recoverable nickel in laterite developed over komatiitic cumulates.
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 ...
Nickel laterites are a very important type of nickel ore deposit. They are growing to become the most important source of nickel metal for world demand (currently second to sulfide nickel ore deposits ). Nickel laterites are generally mined via open cut mining methods. Nickel is extracted from the ore by a variety of process routes.

The Black Swan Ultramafic Succession hosts a number of magmatic Fe Ni Cu PGE sulfide ore shoots, ranging from high grade massive ore to low grade disseminated sulfides. Of these, the most economically significant is the Silver Swan massive sulfide orebody, associated with the basal contact of the succession. The deposit varies in thickness between 5 and 20 m, reaches a N S strike length of 75 ...

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 ...
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).
Pig iron is a main component of stainless steel. Mohr added that nickel prices are expected to remain high until the second half of 2016, when new processing plants start pilot operations. As the Indonesian ore ban continues, many of nickel sulphide projects from around the world are thrust into the spotlight.
Millerite is one of a few sulfide minerals that form fine acicular crystals that appear as hair-like fibers aggregated into sprays.Boulangerite and jamesonite are two other sulfides that form similar acicular crystals. However, jamesonite is gray and brittle and boulangerite has flexible crystals. The oxide rutile and the silicate elbaite, a tourmaline, are two other minerals that can be ...

Sulfide copper and nickel mining should never be attempted on the border of the BWCA. As a lifelong engineer and miner and a native Minnesotan, I feel it …
Sulfide-ore mining for copper and nickel, however, has never been attempted here. In the case of PolyMet, MCEA has led the fight for accountability and true science-based decision-making. MCEA lawyers and experts have time and again cast light on the flaws inherent in the PolyMet proposal, first in the environmental review and permitting ...

Sulphide ores that are mined for nickel and cobalt typically contain 1.5%–3% Ni and 0.05%–0.1% Co. Concentration, Smelting and Converting to Matte. The sulphide ores are concentrated, smelted and converted to metal-rich matte. A schematic diagram of this process is shown in Figure 1.6. The processing steps are as follows:
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 ...
Cobalt mineralisation is typically found in Cu-Co sulphide or oxide ores, Ni-Cu magmatic sulphide ores or Ni-Co laterites. Although the level of detail recorded in the literature varies, cobalt is known to be present in many deposit types ( Crockett et al., 1987, Mudd et al., 2013, Petavratzi et al., 2019, Slack et al., 2017, Smith, 2001 ...
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,
