Nickel extraction from laterite reserves | NICAL Project
Nickel laterites form where ultramafic rocks are exposed to tropical weather. Relatively high temperatures and rainfall cause the destruction of nickel-bearing minerals, olivine and serpentine and the leaching of silicon and magnesium. As a result, iron and nickel accumulate along with other less mobile elements and an iron oxide deposit is …
