Heap Leaching Oxide and Sulfide Copper Ores

Dump leaching is used to recover copper from very low-grade oxide-sulfide pit-waste materials. Here again, leach solutions are percolated downward through a heap. However, in this method, little or no acid is added to the leach liquors prepared drainage pads are not used and the leaching cycle is generally measured in terms of several years.

Copper extraction Wikipedia

Most copper ores contain only a small percentage of copper metal bound up within valuable ore minerals, with the remainder of the ore being unwanted rock or gangue minerals, typically silicate minerals or oxide minerals for which there is often no value. In some cases, tailings have been retreated to recover lost value as the technology for recovering copper has improved.

Copper Oxide an overview | ScienceDirect Topics

Copper oxides are unusual in two respects. First, octahedral-site Cu II:t 6 e 3 contains a single e hole in the 3d shell, which makes it orbitally degenerate and therefore a strong Jahn–Teller ion; consequently, Cu II ions normally occupy square coplanar, pyramidal, or octahedral sites that are deformed to tetragonal (c/a > 1) symmetry by Jahn–Teller orbital ordering.
