Ore Leaching: The Process of Extracting Metals from Ore
The process of leaching is the transfer of ore into a solution of one or more components (usually an aqueous solution) of a solid material. Leaching plays a key role in flotation processes based on the use of particle friction forces, sedimentation of denser particles, etc., since these processes occur in liquid solutions.
