Abstract
The invention discloses a drainage system for an aerated heap leaching operation which comprises a layer of drainage rock (2) which includes a plurality of spaced apart substantially vertically orientated perforated tubes, preferably strip drain tubes (3) comprising a substantially rectangular cross section with a ribbed structure. Aeration pipes (4) extending horizontally through the drainage rock layer are placed adjacent to the strip drains.
