The CONAMA statement said some of the bauxite in the forest ought to be protected from mining, and that even if the law permits it, "we must question whether it is wise to mine the forests due to the extensive damage that would be caused to watersheds, ecosystem services, wildlife and natural resources exceeding any benefits gained for Ghana ...

Bauxite deposits invariably contain a range of impurities, ranging from organic material to trace elements such as Ga, Zn, Pb, P and Be. Table 2.1 shows typical compositions of a range of smelter aluminas. In the Bayer process, many impurities are at least partially soluble in the caustic digestion liquor and may be carried over into precipitation if they are not removed in the desilication ...

Africa leading the Way with Bauxite Production. Bauxite is an aluminium ore. It is known for being the main source of aluminium in the world. Bauxite was first discovered by a French geologist called Pierre Bertheir in 1821 in Provence in the South of France in Les Baux village.

The bauxite is loose and easily mined with front-end loaders. Beneficiation of the ore before it is shipped out of port involves simple screening and washing. Selective mining ensures that only the highest grades are mined. Below the pisolitic bauxite horizon is a nodular ironstone layer.

Bauxite deposits on carbonate rocks are known as karst bauxites. These deposits account for around 14 % of the total bauxite reserves. Karst bauxite ores are rich in REEs [4]. These REEs end up in the bauxite residue during the Bayer's process. The REEs can be recovered from the bauxite residue by direct acid leaching [3, 5–7]. The yield
