In order to improve the circular economy of metals, selective leaching of copper from an intermediate raw material originating from primary base metal production plant was investigated.copper production plant by leaching,MMG Limited | Extraction and ProcessingAfter mining, Copper Oxide ore delivered to the ROM stockpiles is fed into the processing plant through a mineral sizer followed by a semi-autogenous grinding mill (SAG mill). Copper is produced primarily by an agitated leach, counter current decantation and solvent extraction and electrowinning (SX-EX) process.

Heap leaching - Wikipedia

Heap leaching is an industrial mining process to extract precious metals, copper, uranium, and other compounds from ore via a series of chemical reactions that absorb specific minerals and then re-separates them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it.
