Heap leaching Wikipedia

OverviewProcessEnvironmental ConcernsSee alsoExternal links

The mined ore is usually crushed into small chunks and heaped on an impermeable plastic or clay lined leach pad where it can be irrigated with a leach solution to dissolve the valuable metals. While sprinklers are occasionally used for irrigation, more often operations use drip irrigation to minimize evaporation, provide more uniform distribution of the leach solution, and avoid damaging the exposed mineral. The solution then percolates through the heap and leaches both the target and other minerals. This process, called the "leach cycle," generally takes from one or two months for simple oxide ores (e.g. moget price

The mined ore is usually crushed into small chunks and heaped on an impermeable plastic or clay lined leach pad where it can be irrigated with a leach solution to dissolve the valuable metals. While sprinklers are occasionally used for irrigation, more often operations use drip irrigation to minimize evaporation, provide more uniform distribution of the leach solution, and avoid damaging the exposed mineral. The solution then percolates through the heap and leaches both the target and other minerals. This process, called the "leach cycle," generally takes from one or two months for simple oxide ores (e.g. most gold ores) to two years for nickel laterite ores. The leach solution containing the dissolved minerals is then collected, treated in a process plant to recover the target mineral and in some cases precipitate other minerals, and recycled to the heap after reagent levels are adjusted. Ultimate recovery of the target mineral can range from 30% of contained run-of-mine dump leaching sulfide copper ores to over 90% for the ores that are easiest to leach, some oxide gold ores. The essential questions to address during the process of the heap leaching are: • Can the investment of crushing the ore be justified by the potential increase in recovery and rate of recovery?• How should the concentration of acid be altered over time in order to produce a solution that can be economically treated?• How does the form of a heap affect the recovery and solution grade?• Under any given set of circumstances, what type of recovery can be expected before the leach solution quality drops below a critical limit?get price

Leaching Mining Fundamentals

Mar 05, 2014 Heap leaching is also known as acid leaching. This method is most effective for the extraction of metals from difficult ores, and is one of the most tried and tested methods. The pre-processing of ore before leaching involves the grinding and roasting of the ore. Roasting is done to remove the carbonaceous elements trapped inside the ore.get price

TENORM: Copper Mining and Production Wastes Radiation

Mining and Processing MethodsWaste GenerationDisposal and ReuseEPA and The StatesOres that contain copper in the U.S. are typically mined in large, open-pits. Copper processing facilities are usually located near mining or extraction sites. Significant waste volumes are associated with copper production. Mine wastes may contain radionuclides due to their natural presence in ores and can be a source of TENORM. Uranium, which may be co-located with copper ore, may also be recovered as a side stream, if economical. However, in the United States this is not a general practice. Learn more about ur
