Nickel Smelting And Refining Process

Environmental Guidelines for Nickel Smelting and Refining

2018-8-5  Various processes are used to refine nickel matte. Fluid bed roasting and a chlorine-hydrogen reduction will produce high grade nickel oxides (95%+ nickel). Vapor processes, such as the carbonyl process, can be used to produce high purity nickel pellets. In this process, copper and precious metals remain as a pyrophoric residue requiring separate treatment. Electrical cells equipped with inert

2021-8-22  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

Nickel: smelting, producing-Metalpedia

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.

What Is Nickel Smelting? (with picture) Info Bloom

The next process in nickel smelting is refining the liquid matte, which is typically done with one of two processes. With fluid bed roasting, sulfides are added to the liquid matte and the two are roasted together, eventually leaving just the nickel metal.

Extraction and Refining of the Platinum Metals

to make anodes for the electro-refinery. In the meantime, nickel matte from the blast furnace operation is broken, crushed and ground in ball mills to 20 mesh. This material is then roasted to nickel oxide in oil-fired 17-feet diameter Herreschoff type furnaces with two hearths separated by an air gap. Ground nickel matte is fed through a hopper on to the top hearth which is kept at a low temperature; it then falls through to the lower hearth which is kept at 900' to 950°C. After cooling, the resultant nickel oxide

Processing of PGM containing Ni/Cu bulk concentrates in

Matte refining is based on atmospheric pre-leaching and total pressure leaching. Nickel, cobalt and iron are leached leaving a leaching residue containing small amount of gangue minerals and PGM’s. Iron is removed from the leach solution in an autoclave to produce high quality hematite as by-product.
