Guinea. Guinea is rich in natural resources and is known as a "geological miracle". There are large reserves of aluminum and iron ore with high grade, among which the proven reserves of aluminum ore rank first in the world. In addition, there are diamonds, gold, copper, uranium, cobalt, lead, zinc, etc.
For the production of 1 tonne of alumina, 8–10 tonnes of mining Bauxite wastes are generated. It is important to note that most of the Bauxite mining wastes generated are PLK rock containing 40–55% Al 2 O 3, 0.3–30% Fe 2 O 3, 0.97–3% TiO 2, 20–30% SiO 2 and 20–30% LOI. In spite of having the metallurgical grade of Al 2 O 3 it …
