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. Hence, …
