MINING AND PROCESSING : The mining methods vary depending on the type of ore being mined. Since nickel is found in two types of ores, each of them is mined differently. Sulfide ores are typically mined using underground mining methods, although open-pit mining can also be utilized in the initial stages.

Primary world nickel production in 2020 was 2430.7 kt Ni; 69% (1677.7 kt) of them came from oxidized nickel ores (laterites) and 31% from sulfides. Production-wise, 87.7% of the 1677.7 kt came from pyrometallurgical and 12.3% from hydrometallurgical processes. For a long time, Fe-Ni had a 20–40% Ni analysis, but in 2006 a new Fe-Ni quality came into the scene. This is the …

Mining nickel directly is the obvious route to obtaining pure nickel, however, nickel can also be recovered as a by-product of other metals. For example, copper electrolysis requires a bleed to eliminate the buildup of impurities that accumulate over time as a result of the electrorefining of impure copper anode to produce a pure metal cathode. A bleed is required when certain …
