A variation of heap leaching involves constructing the heap in a dump, and calling it dump leaching. Large containment vessels are being used on a basis as well. Both heap leaching and borehole mining have become the favored exploitation methods for recovering uranium. This figure illustrates a heap leaching operation.
Heap leach mining is an industrial hydrometallurgical process, where the metal contained in an ore body is extracted by dissolution. The target mineral is leached with an aqueous solution whereby the mineral is dissolved into what is called a pregnant solution which, is then captured and later recovered downstream in the processing line.
Heap Leaching Heap leaching is an industrial mining method to dig out precious metals and copper compounds from ore. Process of heap leaching The mined ore is crushed into tiny chunks and heaped on an impermeable plastic and/or clay lined leach pad where it may be irrigated with a leach solution to melt the valuable metals.
