ABSTRACT:
A procedure to agglutinate ore concentrations, which can be of copper, on a gravel heap, to be leached on a non-flooded bed which comprises: artificially adhering the concentrate to the surface of a solid material base, which can be an artificial material, or a stony substance; the agglutinated material is stockpiled, forming a leaching pile; and is irrigated with a leaching solution containing at least Cl, Cu, and Fe ions.
