Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and re-separate them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the

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

With nickel found in two radically different types of ore, it is not surprising that the mining methods differ. Sulfide deposits are usually mined by underground techniques in a manner similar to copper, although some deposits have been mined using open pits in the early stages. The mining of laterites is basically an earth-moving operation, with large shovels, draglines, or front-end loaders

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
