Definition

A solution containing solubilized metal ions.


Origin

  1. Caused by leaching. The metal bearing solution is then called leachate.
  1. Applied leaching

Pregnant leach solution (PLS) – leachate from applied leaching operations intended for subsequent metal recovery

Bleed from metal production processes – a solution taken from a closed process stream in order to remove unwanted metal ions that otherwise would build up to high levels ARD

Natural

Anthropogenic

Not caused by leaching
