The making of nickel is a process which involves a number of steps: 1. Mining. Nickel mined from lateritic ore is mined from various depths beneath the surface using large earth-moving equipment. The other nickel containing type of ore, sulfidic ore, is usually found in combination with copper ore and is mined underground.

Sulfide ores are crushed and ground in order to liberate nickel minerals from the waste materials by selective flotation. In this process, the ore is mixed with special reagents and agitated by mechanical and pneumatic devices that produce air bubbles. As these rise through the mixture, the sulfide particles adhere to their surfaces and are ...
