Stockpile - Wikipedia

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. Stockpiles are normally stacked in stockyards in refineries, ports and mine sites.
