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.

The ore extracted from Raglan Mine is crushed, ground and processed on-site to produce a nickel-copper concentrate, which is then sent to the Sudbury Smelter for further processing. The concentrator treats approximately 1.3 million tonnes of ore yearly, resulting in more than 38,000 tonnes of nickel-in-concentrate annually.

Smelting - an overview | ScienceDirect Topics

Smelting of concentrates containing platinum-group elements requires more energy than smelting of hot nickel–copper calcine. Smelting platinum-containing concentrates requires about 800 kWh/tonne of concentrate, whereas smelting calcine requires about 500 kWh/tonne of calcine (Warner et al., 2007).The reasons for this difference are:

Nickel: smelting, producing-Metalpedia

Nickel: smelting; Extraction and purification; Nickel is recovered through extractive metallurgy: it is extracted from its ores by conventional roasting and reduction processes that yield a metal of greater than 75% purity. In many stainless steel applications, 75% pure nickel can be used without further purification, depending on the composition of the impurities.

Impacts of Smelting - Base Metal Smelting

Impacts of Smelting; Impacts of Metal Smelting Impacts on Environment. Smelting is known to be a major cause of pollution in the environment. When smelting occurs, along with the metal produced, a solid waste product, called stag, is also produced [1]. This slag is emitted into the air and can be a cause of the pollution although not a major one.
