Using nickel flash smelting technology it is possible to process sulfide nickel concentrate and produce nickel matte and slag in a relatively efficient process. Any materials resulting as smelting and converting slags are recirculated in the electric furnace and recovered where possible as nickel matte. Nickel (Ni) is a silvery-white, hard metal.

The largest furnace that Electric Smelters has built is smelting 100 tons of iron ore in Norway (per day, presumably). This was erected in 1916 but is not mentioned in Millers report of 1936 cited later. The smallest furnace has a capacity of 750 pounds in 24- hours and is employed for reducing precipitates.

Alex Newth Nickel ore must melt until it becomes a product known as liquid matte, which is usually around 45 percent nickel. Nickel smelting is the process that nickel ore goes through to eventually remove impurities and leave just the nickel metal. While the ores can come from different stones and sources, they have two categories: lateritic, or rocks found in tropical …

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.
