The choice of mining method for nickel extraction depends on several factors, including the deposit type, location, depth, and ore characteristics. The two primary mining methods used for nickel extraction are: 1) Open-Pit Mining: Open-pit mining is the most common method used for nickel mining, especially for large, near-surface deposits.

Challenges in processing nickel laterite ores by flotation
It should be added that segregation of laterite ores prior the flotation process has shown some improvement in upgrading nickel. The segregation process relies on the addition of calcium chloride or sodium chloride and carbon allowing the formation of nickel and iron chlorides at temperatures between 900 and 1150 °C. Iwasaki et al., (1961) and Nagano et al., (1970) …
