Ore genesis

Nickel is a chalcophile element which prefers sulfides, so an ultramafic or mafic rock which has a sulfide phase in the magma may form nickel sulfides. The best nickel deposits are formed where sulfide accumulates in the base of lava tubes or volcanic flows — especially komatiite lavas.

 · FERRO NICKEL ORE- A recent development in the extraction of nickel laterite ores is a particular grade of tropical deposits, typified by examples at Acoje in the Philippines. This ore is so rich in limonite (generally grading 47% to 59% iron, 0.8 to 1.5% nickel and trace cobalt) that it is essentially similar to low-grade iron ore.

Processing nickel sulfide minerals by flotation always presents the challenge of obtaining appropriate selectivity between nickel sulfide and other sulfides, such as pyrrhotite, pyrite, and chalcopyrite. Other minerals that can reduce the process efficiency and the concentrate quality include minerals that contain magnesium (e.g., talc).

Hydromet Technology

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.

Smelting of Nickel-Copper and Nickel Sulfide

Smelting of Nickel Sulfide Ore. The selection of process flow depends on the type of raw materials, composition and product requirements. Sulfide ores are mostly smelted by matte-making. Different pyrometallurgical processes are used to produce low-nickel matte from various nickel sulfide ores.


Apart from Fe, other heavy metals which are produced from oxide ores are: Manganese, Chromium, Titanium, Tungsten, uranium and Tin. Sulphide ores: Copper ore (CuFeS2, Chalcopyrite), sphalerite (Zn,Fe)S, Galena PbS, Pyrite FeS2. Others: Nickel, Zinc,Mercury and Molybdenum Halide ores: Rock salts of Sodium, Magnesium chloride in sea water.

Sulfide Ore

3.3.1 Nickel extraction process and nickel slag formation. Primary nickel is produced from two very different ores: sulfide ores and laterite (oxide) ores. Sulfide ores, which are generally mined from underground and often found in conjunction with copper-bearing ores, contain copper–iron sulfides in association with nickel–iron sulfides.

Nickel Mines, Nickel Extraction Process, Nickel Recovery ...

When process copper-sulfide nickel ore, collector and frother will be used in order to better results. A basic principle of copper-sulfide nickel ore process is that it is better to let copper assimilate into nickel ore rather than the opposite. For it is easier to recovery cooper from nickel concentrate.

A New Process for Cobalt Nickel Separation

excellent cobalt-nickel separation primary leach liquor by Cyanex 272. However, manganese extraction from the leach liquor along with cobalt could not be avoided, thus increasing the cost of the process. For sulphide ores, there is another alternative; if the ore can be concentrated by flotation, matte smelting is used instead of leaching.

Nickel element extraction, mining technique – flash ...

The extraction from the sulfide ores is a huge process involving froth floatation, smelting and electrolysis. Firstly, the sulfide ores are crushed and ground to liberate nickel containing minerals from the waste material by floatation process where the ore is mixed with certain reagents and disturbed by mechanical devices that produce air bubbles which rise above the mixture and are collected ...

Processing of Nickel Laterite Ores on the Rise

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).


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,

Lateritic ores contain chemically-bound water that must first be removed through a drying process in high-temperature kilns. Nickel and Copper sulphide ores need further crushing and grinding to liberate the valuable minerals from rock. The mixture, or slurry, is fed into a rotating mill, where heavy steel rods or balls grind the rock. The ore is
