Heap leaching is a hydrometallurgical process where solution is applied to dissolve minerals in ore, and the solution is processed to recover the minerals. Heap leaching has been practiced since the mid-sixteenth century when miners in Hungary began applying this technology to extract copper from low grade ores. The technology is successfully used to extract gold, silver, copper, nickel and uranium, among others.
Due to its low capital and operating costs, heap leaching has long been an attractive option for the recovery of base and precious metals from low grade ores. Ore grades have decreased significantly over the past several decades, and are continuing to decrease. With this trend in ore grades, heap leaching is increasingly becoming the preferred method for mineral extraction.
This live webcast is for those individuals who wish to gain a basic understanding of the design, construction, operational, and closure considerations for heap leach facilities (HLFs). This includes recent graduates and entry level design professionals that need to know about heap leaching technology, entry to mid-level geotechnical, civil, or process design engineers with little experience in heap leaching, mine operators, due diligence and environmental professionals who want to gain a full lifecycle view of these facilities, regulators, and anyone interested in the subject.
