Chemo-physical concentration of a Low-grade nickel laterite ore
1. Introduction. Nickel natural resources mainly occur as two types of sulfidic and lateritic (oxidic) ores. Despite the large share of the world lateritic nickel resources (about 70%), nickel is mostly extracted from sulfides (Dalvi et al., 2004).The reason is that nickel in sulfidic ores is aggregated as particular minerals such as pentlandite, while nickel in laterites is …
