Mulanje
Spectacular mountainous area rising to some 3000 m from Palombe Plain. (750 m) and extending over 640 km².
There are several areas of bauxitization on Mlanje but the only potentially economic ones are on the Lichenya Plateau in the SW of the complex. Reserves of 50-60 million tons averaging 43% Al₂O₃, 14% Fe₂O₃ and 17% free quartz ave been proved (Garson & Walshaw 1969).
