Nickel processing - Extraction and refining | 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. This is done in a rotating converter of the type used in copper production. The slag is drawn off, leaving a matte of 70Nickel Ore Mineral Processing - hotminingepc,When floatability difference happens to the various nickel elements in the raw ore, the nickel ore can be recycled from tailings after the copper and nickel did the mixing flotation. Copper- Nickel Ore Flotation Process: A basic principle of copper-sulfide nickel ore process is that it is better to let the coppers assimilate into the nickel ore. Because it is easier to recovery cooper from the nickel concentrate. The process has a best advantage-get the copper concentrateNickel processing | Britannica,Nickel alloys exhibit a high resistance to corrosion in a wide variety of media and have the ability to withstand a range of high and low temperatures. In stainless steels, nickel improves the stability of the protective oxide film that provides corrosion resistance.
