A binder composition is shown for agglomerating ore fines in a heap leaching ore recovery process. The binder composition comprises a calcareous component, a sulfate component and a siliceous-aluminous component such as fly ash. The ore fines are agglomerated by adding the binder composition thereto and a leach bed is formed of the agglomerated ore. The leach bed is leached with a leaching agent to form a leach liquor the metal values are recovered from the leach liquor. |
