Nickel Smelting and Refining Industry Description and Practices Primary nickel is produced from two very dif-ferent ores, lateritic and sulfidic. Lateritic ores are normally found in tropical climates where weath-ering, with time, extracts and deposits the ore in layers at varying depths below the surface. Lat-

Nickel carbonyl passes through smaller chambers that circulate the material at temperatures of about 450℉. This creates a fine, pure nickel powder. Lateritic Ore Processing. The high iron content of lateritic ores makes smelting the preferred method of nickel extraction.

Smelting process are governed by two basic chemical facts: -Separation of Nickel from Oxide gangue components such as silica. and magnesia is readily achieved by smelting, due to large. differences in the free energies of formation. -Only partial separation of nickel from iron is possible by selective.

Nickel mining in Indonesia began with small-scale exploratory mining operations during the Dutch East Indies era and began to expand in the 1960s. Most of Indonesia's proven nickel reserves are located in the islands of Sulawesi and Halmahera, and the country has the largest annual production and reserves of nickel in the world.

While sulfide nickel ores are processed via upgrading to concentrates and then smelting, this approach is not applicable to laterite ores. A variety of approaches are available to process nickel laterite ores, with the most prevalent approaches explained below. The method(s) chosen is dependent on the composition of the unique ore source.

Nickel requires higher smelting temperatures (in the range of 1,350 °C [2,460 °F]) in order to produce an artificial nickel-iron sulfide known as matte, which contains 25 to 45 percent nickel. In the next step, iron in the matte is converted to an oxide, which combines with a silica flux to form a slag.

The Flash Smelting Process is the cleanest smelting method available, giving high recovery of metals with low investment and operating costs. In collaboration with Norilsk Nickel, we're able to provide customers with the resources and expertise they need to achieve their goals and further optimize their production.
