Dump leaching - Wikipedia
Dump leaching is an industrial process to extract precious metals and copper from ores.
Leaching: Types, Methods, Advantages, Disadvantages - Science …
Aug 12, 2023 · Dump leaching. Heap and in-situ leaching characteristics are combined in dump leaching. Depending on the dump location, an impermeable layer may or may not be employed in a dump leach. The ore is dumped to allow similar processing to heap leaching, but the geological conditions of the area allow a valley or pit to act as the sump. Vat leaching
Dump leaching consists of truck end-dumping of ore broken only by the drilling and blasting of mining activ-ity. After completion of ore placement, the surface is ripped using bulldozers to break up compaction layers and improve solution distribution uniformity.
How copper dump leaching works - ScienceDirect
Sep 1, 2021 · In copper dump leaching, run-of-mine ore is irrigated with acidic leaching solution to generate aqueous cupric ions for further processing. The very large size of the ore particles being leached, as much as two meters in diameter, should preclude any significant metal recovery.
Copper Leaching Practices - 911Metallurgist
Feb 5, 2021 · Dump leaching is used to extract copper from waste material produced during the large-scale open-pit mining of copper ore deposits. Almost all of the copper oxide and sulfide minerals encountered in such deposits are leachable by this method, since the leach cycle is measured in years.

Aug 3, 2019 · The dump leaching of low-grade copper ores, as an integral part of the open-pit mining operations in the Southwest, has been practiced for the last fifty years and is increasing in importance as one of the major sources of copper.
a) Dump Leaching In most applications, dump leaching is a convenience for open pit mining operations to dispose of lower grade or waste rock (typically below 0.2% Cu) (4) and stripped material with the intention of recovering the valuable metals contained therein (Figure 1). Dump design is dictated by topography and haulage costs.
Heap Leaching - an overview | ScienceDirect Topics
Heap leaching is conducted on ore stockpiles (traditionally called dump leaching) to static heaps to on–off dynamically loaded pads. In stockpile ore leaching, low grade ore is removed from the mine and stacked in an area of convenience which has naturally occurring impermeable soil.
Dump Leaching Hydrology - 911Metallurgist
Jan 10, 2019 · In general, a dump leaching system used for extraction of copper consists of a mineralized waste dump usually containing rock too low in grade to extract; a leach solution application system suitable to the rock/ore type and dump construction; and a recovery system capable of capturing the maximum solution flow.
