Heap leaching involves trickling a leach solution though a bed of ore to extract target metals The bed of ore (or heap) is built, often with crushed ore, and engineered to achieve percolation of the leaching solution to all regions The leach solution interacts with the solid, where the lixiviant dissolves the target minerals from the solid into the solution, and the dissolved species areWHY SELECT HEAP LEACHING AS THE PROCESSING METHOD? Gold and silver can be recovered from their ores by a variety of methods, including gravity concentration, flotation, and agitated tank leaching Methods similar to heap leaching can be employed: dump leaching and vat leaching (vat leaching is the treatment of sand or crushed ore in bedded vats with rapid solution percolation) Typically, heapPrecious Metal Heap Leach Design and Practiceissues and processing technologies for heap leaching intensification in severe climatic conditions The paper presents perspectives for heap leaching of sulfide and mixed ores from the Udokan (Russia) and Talvivaara (Finland) deposits, as well as technogenic waste dumps, namely, the Allarechensky Deposit Dumps (Russia) The paper also shows the laboratory results of nonferrous metalsHydrometallurgical Processing of LowGrade Sulfide Ore and
