Definition

A solution containing solubilized metal ions.


Origin

Caused by leaching. The metal bearing solution is then called leachate.
  • 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
  • Industrial effluents and by-products
