At least 15 manganese deposits crop out in the West African craton in Mali, Burkina Faso, Ghana and Cote d'Ivoire. There average grade estimates range from 17 to 52% total Mn oxide and average volume of 5–19 Mt of ore; they consequently provide an attractive target for exploration and eventual exploitation.The Tambão and Béliata Mn oxide deposits in the Oudalan …
