  • What Is Nickel Smelting with picture

    Feb 15 2022  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
