Laterite is a soil type rich in iron and aluminium and is commonly considered to have formed in hot and wet tropical areas. Nearly all laterites are of rusty-red coloration, because of high iron oxide content. They develop by intensive and prolonged weathering of the underlying parent rock, usually when there are conditions of high temperatures and heavy rainfall with alternate wet and dry

2022.8.22 Most of the laterite contains 0.7 to 1.84 wt% of Ni, and recovery with leaching in all the cases is more than 85%. Recovery is more than 90% for laterite with more than 1% nickel content irrespective of mineralogy. Table 12 explains that atmospheric leaching shows less nickel recovery with sulfuric acid leaching than with NAPL.
