What Is Nickel Smelting? (with picture)
02-05-2020 · 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 climates and which contain nickel; and sulfidic ore, which is mined from underground.
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.

makes them more challenging to process economically. Smelting and refining of massive sulphides begins with the flotation of ore, typically in the range of 0.2-2% nickel, to an acceptable concentrate grade of 10 to 20% nickel. Concentrate smelting produces a high grade nickel matte which is then refined hydrometallurgically.
