Laterite deposits usually contain both an upper dark red limonite and lower bright green saprolite zone Due to the different quantities of iron magnesium and silica in each zone they must be processed differently to cost effectively retrieve the nickel In general the limonite zone is higher in iron and lower in nickel magnesium and silica
