(57) A process (10) for extracting manganese from manganese-bearing ore includes roasting (12.2) a feed admixture of particulate manganese-bearing ore (26), comprising Mn and Fe, and ammonium sulphate (24) at a first temperature T1 to provide a sulphonated admixture comprising MnSO4(s) and FeSO4(s). The sulphonated admixture is roasted (12.3) at a second temperature T2, which is higher than the first temperature T1, to form a leachable admixture (30) comprising MnSO4(s) and Fe2O3(s). The MnSO4(s) is leached (16) in preference to the Fe2O3(s) from the leachable admixture (30) to provide a leachate (34, 38) rich in dissolved MnSO4.
