How will the mining waste be disposed of?
Alcoa will use technologies that minimize environmental impact. In general the mining industry uses appropriately sealed tanks where bauxite waste (resulting from washing the mineral) will be deposited until it reaches the solid concentration that is desirable for it to be sent to recompose the terrain. The following stage is that of replacing the vegetation itself. The absence of chemical products in the whole of the bauxite washing process, and consequently in the waste produced, has to be emphasized.
