This and the high cost of working underground explain why underground orebodies must contain higher grades of nickel ore than open-pit orebodies. Ore grade has a direct effect on mine investment costs expressed in US$ per annual tonne of nickel. Consider two identical ore bodies, one containing 1.25% Ni ore and the other containing 2.5% Ni ore.

Nickel is re-obtained from the nickel carbonyl by one of two processes. It may be passed through a large chamber at high temperatures in which tens of thousands of nickel spheres, called pellets, are constantly stirred. It then decomposes, depositing pure nickel onto the nickel spheres. Alternatively, the nickel carbonyl may be decomposed in a smaller chamber at 230 °C to create a fine nickel

Nickel refining Various processes are used to refine nickel matte. Fluid bed roasting and a chlorine-hydrogen reduction will produce high grade nickel oxides (95%+ nickel). Vapor processes, such as the carbonyl process, can be used to produce high purity nickel pellets. In this process, copper and precious metals remain as a

Researchers at Aalto University developed a method that uses chloride for the leaching and recovery of gold from ore. Scientists propose new ‘salty’ non-toxic gold extraction process
Nickel occurs in ore bodies, and breaking down these ore bodies to extract nickel expends energy. Producing nickel requires ample supplies of coal, electricity and crude oil. Mines and blast furnaces utilize energy to extract nickel ores from the ground and process it into nickel. These costs can have a big effect on primary production
