Reductive Leaching of Limonitic Laterites Using Ferrous Sulphateum sulphate media using ferrous sulphate as reductant. Different parameters were examined, such as total ammonia concentration, temperature and ferrous sulphate concentration. At 80°C, 130 g/l of total ammonia, 2.73 g FeSO4/ g ore and pH 8.2, nickel extraction was 64 % while 20 % of cobalt remained in solution after 8 hours.
