Heap leaching is anindustrial miningprocess used to extractprecious metals,copper,uranium, and other compounds fromoreusing a series of chemical reactions that absorb specific minerals and reseparate them after their division from other earth materials.

Heap leaching is a simple means of recovering copper from oxide andoxide-sulfide ores. Although this method requires relatively low capital investment, it suffers from low copper recoveries and relatively high acid consumption.

The hydrometallurcial approach to refining copper ore is known assolvent extraction electro-winning(SX-EW), orleach solvent extraction electro-winning(L-SX-EW) for its convergence with the heap leaching technique.

At the Steptoe mill, in Nevada, a smallleaching annexis treating oxidizedcopper orein conjunction with flue dust at a cost of $0.08 perpound copperrecovered. The actual cost ofcopper produced by leachingmethods is, however, not of so much importance as the fact thatoremay be handled in this manner which is not amenable to reduction by any other process.

TENORM:Copper MiningandProduction Wastes. When processing copper through heap leaching, High levels of TENORM have been found in the PLS of twoin-situ leachoperations in Arizona.Copper smeltingand refining facilities produce 2.5 million metric tons (MT) ofsmelter slagand 1.5 million MT ofslag tailingsper year.

TheLady Annie CopperProject, located 137 km north of Mount Isa, is a large medium grade oxidecopperresource. The project is a 2.6 Mt/ycopper heap leachingoperation comprising crushing, agglomeration, stacking,heap leaching, solvent extraction and electro winning (SXEW) to produce 19 000 t/y of LME A Gradecoppercathode.

Jul 10, 2017·Heap leachingis used in tandem with electrowinning, forcopperextraction; approximately 16% of the world’s totalcopper productionis extracted in this way. The Radomiro Tomic mine in Chile is a prime example of the success ofcopper heap leaching, …

Theleachingcycle covers a span of many years. The percentage ofcopperproduced byleachingoperations has increased and this trend is expected to continue. Currently, there are 18 commercially activecopper leachingoperations in the United States with a totalproductioncapacity of 280,000 metric tons ofcopperper year.

Fluoris the world leader in development of hydrometallurgical and pyrometallurgical processingplantsfor thecopperindustry. Our project experience extends from initial evaluative studies to the engineering, design and construction of concentrator facilities, smelters, electrorefineries,heap leach, solvent extraction and electrowinning projects.

About 80% of the world'scopper-from-ore is produced by concentration/smelting/ refining of sulfide ores. The other 20% is producedby heap leaching/solvent extraction/electrowinning of oxide, and chalcocite ores.Copper productionfrom recycled end-of-use objects is about 15% ofcopper-from-orecopper production.

Mar 28, 2020· Theheap leachingprocess is used to extract metals such as gold,copper, and nickel and may be used on low grade ores and mining tailings which are generally considered to be of no commercial value. The process also produces yellowcake, a concentrate leached from uranium ore used in theproductionof nuclear reactor fuel.
