Abstract

The invention relates to an air distributor (1) for a bio-assisted heap leaching system which comprises a pipe having a series of apertures through the wall of the pipe, with the series of apertures (3) configured operatively to face downwards, and to be located in an indentation (2) in the outer wall of the pipe. The invention also extends to a heap leaching system, method of forming a bio-assisted heap leaching system, and a method of bio- assisted leaching of a heap which utilizes such an air distributor.
