Aug 27, 2020· Heap leaching: The ore is arranged in large heaps and treated as in slope leaching. 3. In situ leaching: Water containing Thiobacillus is pumped through drilled passages to unextracted ore which remains in its original location in the earth. In most cases, the permeability of the rock must be first increased by subsurface blasting of the rock.

The mined ore is crushed into small chunks and heaped on an impermeable plastic and/or clay lined leach pad where it can be irrigated with a leach solution to dissolve the valuable metals. Either sprinklers, or often drip irrigation, is used to minimize evaporation. The solution then percolates through the heap and leaches out the precious metal.

Heap leaching is one of the oldest and the most traditional mining process used to extract valuable metals from specific minerals. This is a hydrometallurgical process in which the solution is applied for the dissolution of minerals from the ore that is used for the extraction of metals. Originally heap leaching was practised 500 years ago.
