Nickel industry
Two broad ore types. Nickel occurs in two broad ore types: laterite (oxide) ores, principally located in tropical and sub-tropical areas, and; sulfide ores, principally located in the temperate to sub-Arctic regions. Major nickel mining locations are depicted in the map – but some of these locations have many operations, and some only one.

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 …

Roasting and Leaching Behavior of Nickel Laterite Ore
The success of the sulfation-roasting-leaching process depends on iron behavior. Due to its higher amount, it is sulfated before nickel. However, the stability of iron sulfates is lower than the nickel sulfate and during the decomposition of iron sulfate, the sulfur xide (SO 3) is liberated and reacts with nickel to form nickel sulfate.This …

Separation of Nickel and Cobalt from Nickel and Cobalt
It is found that the maximum separation coefficient of nickel and cobalt is 1.2 × 10 4 at the extraction ratio of 1:1. Under this extraction ratio, the more extraction amount of cobalt, the less extraction amount of nickel. It realizes the effective separation of nickel and cobalt. Therefore, the best extraction phase ratio is regarded as 1:1.
