Heap Leaching of Gold and Silver Ores - ScienceDirect

Heap leaching involves stacking of metal-bearing ore into a heap on an impermeable pad, irrigating the ore for an extended period of time with a chemical solution to dissolve the sought-after metals, and collecting the leachant as it percolates from the base of the heap.

Heap leaching: Could it be an alternative to conventional .

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.

Heap Leaching - an overview ScienceDirect Topics

Heap leaching was initially applied to acid leaching of copper oxide ores and later extended to secondary sulfides and mixed oxide-sulfide copper ores. By introducing bacterial activity and forced aeration to the heaps, an oxidative environment suitable for sulfide oxidation can be achieved.

Originally, heap leaching was practiced 500 years ago. Georgius Agricola published a book De Re Metallica in 1557 and reported that the heap leaching process was finished in a 40-day cycle 1 . Since the middle of the 16th century, heap leaching was practiced in Hungary for copper extraction.

Agglomeration technique improves heap leaching process .

Heap leaching relies on a leaching agent moving through a bed of heaped ore to extract the metallic components: Crushed ore is stacked on a leaching pad and irrigated with the leaching agent. The leaching agent chemically reacts with the metal in the ore to dissolve the copper into the solution as it percolates through the heap.

PRETREATMENT OF COPPER ORE PRIOR TO HEAP LEACHING

leaching tests were conducted to evaluate the quality of the agglomerates. Experimental results reveal that a mixture containing 85 to 90% ore, 7 to 10% sulfuric acid solution and 3 to 5% stucco binder produces high quality stucco binder agglomerates that leach as well as, if not better than, liquid bridge agglomerates.
