Nickel: smelting, producing-Metalpedia

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

Nickel smelting and refining: A long road ahead for Indonesia

When Indonesia placed export restrictions on nickel ore early last year, the plan was to encourage the country’s mining firms to develop their own smelting and processing facilities so that Indonesia could export refined ores and concentrates, which are worth more in the market than raw ones.

Nickel Smelting and Refining

Nickel Smelting and Refining Industry Description and Practices Primary nickel is produced from two very dif-ferent ores, lateritic and sulfidic. Lateritic ores are normally found in tropical climates where weath-ering, with time, extracts and deposits the ore in layers at varying depths below the surface. Lat-

What Is Nickel Smelting? (with picture)

18/10/2019  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.
