摘要

An aeration system for a bed of ore that is laid upon a basal layer has a gas source located upstream for supplying gas and aeration pipes that distribute the gas downstream to the bed. Each aeration pipe has spaced-apart gas emitters that distribute gas to the bed and the aeration pipes extend through the bed towards the basal layer.
