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: smelting, producing-Metalpedia,Outotec® Nickel Flash Smelting Process is a benchmark nickel-smelting method and a clear global leader in the world’s primary nickel production from sulfide raw materials. Efficiency and improved environmental and in-plant hygiene have been the guiding principles in developing the process.Nickel processing | Britannica,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.
