Nickel Ore Process, Nickel Ore Mining Equipment

Copper- Nickel Ore Flotation Process When process copper-sulfide nickel ore, collector and frother will be used in order to better results. A basic principle of copper-sulfide nickel ore process is that it is better to let copper assimilate into nickel ore rather than the opposite. For it is easier to recovery cooper from nickel concentrate.

What Is Nickel Smelting? (with picture)

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 climates and which ...

History. Nickel ore was first prospected in Indonesia (then known as Dutch East Indies) in 1901 in the Verbeek Mountains of Sulawesi by a Dutch mineralogist, with further discoveries in what is today Kolaka Regency in 1909. A Canadian geologist from Inco further prospected the existing deposits and in 1934 exploration efforts from a Dutch mining firm began.
