Solution

The correct option is D Leaching
Bauxite ore is concentrated by the process of leaching. It is a process in which a suitable solution is added to the ore. A chemical reaction takes place between ore and solution in which the ore dissolves in the solution. The insoluble impurities are filtered off. The pure ore is seperated from the filterate by a chemical reaction.
