    Heap leaching is a common extraction technique employed in the processing of metals such as gold copper silver and uranium. A typical heap leach operation involves ore excavation from open pit or underground mining milling of the ore to a particular required size and then heaping the crushed ore on an impervious pad. The ore heap is subsequently leached with a solvent such as a diluted acid

    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

    This ore is the most important source of iodine in the world and is processed mainly by heap leaching using water as a leaching agent. Heap leaching of caliche ore is carried out by the stacking of ROM (RunOfMine) material where the particle size distribution covers a wide range from a few millimeters up to several decimeters even diameters about 1 m. During the leaching the multiple

    Crushed ore heap leaching involves reducing ROM ore to a predetermined optimal target size distribution sometimes with topsizes as small as 12.5 mm (0.5 in.) or even finer through multiple stages of crushing. Crushing increases surface area and mineral liberation which in turn result in higher more economic recovery. Crushed ores are often agglomerated to bind fines and clays with the

    It is a flexible and continuously evolving extraction technology which gained popularity in the 1980s when gold prices rocketed from $35 to $800. Developers and miners took advantage of the higher prices and opened mines with grades as low as 23 grams per ton gold. Heap leach mining methods are generally used on open pit mines with ore that is near surface and has been oxidized. Heap
