    Hydrometallurgical processing of nickel laterites (limonites or saprolites) requires acidic conditions to dissolve the nickel within the laterite ore. This acidic solution is neutralized in several steps using lime, precipitating the dissolved element impurities from solution and recovering valuable base metals (Ni, Co, Cu) as precipitate products.
