What Is Nickel Smelting? (with picture) wiseGEEK

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.
