A stockpile is a pile or storage location for bulk materials, forming part of the bulk material handling process. Stockpiles are used in many different areas, such as in a port, refinery or manufacturing facility. The stockpile is normally created by a stacker. A reclaimer is used to recover the material.

The process of liberation of copper ores depends upon whether they are oxide or sulfide ores. Subsequent steps depend on the nature of the ore containing the copper. For oxide ores, a hydrometallurgical liberation process is normally undertaken, which uses the soluble nature of the ore minerals to the advantage of the metallurgical treatment plant.
