Where Does Nickel Come From? Nickel is the fifth most abundant element in the Earth, but most of that nickel is located in the core, more than 1,800 miles below the surface.In Earth's crust, two major types of ore deposits supply most of the nickel used today: magmatic sulfide deposits (such as the pentlandite and pyrrhotite deposits found at Norilsk, Russia; …
Refining of Copper. Copper refining is a process that involves multiple steps. Usually, it starts with a copper concentrate that is smelted to produce impure copper anodes. Then the anodes are electro-refined to produce an LME Grade A copper cathode (+99.99%). One of the most important factors in the refining of copper is the control of …
