Extraction and refining. The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used. The major differences in equipment are the use of higher-temperature refractories and the increased cooling required to accommodate the higher operating temperatures in nickel production.

FREE Extraction and Processing of Copper Essay

Each type of ore has a method to process and extract. If the ore is parallel with the surface, it is best to use an open pit mine because it would be more economical to strip the top off the ore until it's able to mine across the top of the ore. If the ore is at a steep angle to surface, you can ...
