Nickel processing - Nickel processing - Extraction and refining: The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used. The major differences in equipment are the use of higher-temperature refractories and the increased cooling required to accommodate the higher operating temperatures in nickel ...
Nickel processing, preparation of the metal for use in various products. Although it is best known for its use in coinage, nickel (Ni) has become much more important for its many industrial applications, which owe their importance to a unique combination of properties. Nickel has a relatively high

Flash smelting (Finnish: Liekkisulatus) is a smelting process for sulfur-containing ores including chalcopyrite. The process was developed by Outokumpu in Finland and first applied at the Harjavalta plant in 1949 for smelting copper ore. It has also been adapted for nickel and lead production.

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. As such, certain steel smelters in China have developed a process for blending nickel limonite ore with conventional iron ore to produce stainless steel feed products.

nickel pig iron (<15% Ni) in mini blast furnaces. The difficulty of smelting high iron limonite in a conventional RKEF process is to control iron reduction and, if the liquidus temperature of the slag is less than that of the alloy, the high slag superheat necessary to keep the alloy molten.
Because fine ore particles are readily treated in a DC-arc furnace, units such as fluidized beds (which require materials of small particle size) can be used for the pre-treatment stage of the process. A process has been developed whereby nickel laterites of a wide compositional range can be smelted in a DC-arc furnace, to produce ferronickel.
3. Calcination dehydrate the ore and to pre-reduce the nickel and iron oxide at about 800 - 1000 C results in a furnace feed that contains the nickel as a metal and the pre-reduced iron, mostly in the form of iron (II) oxides. 4. Smelting takes place in open bath semi-closed electric arc furnaces with submerged electrodes. 5.
