ABSTRACT:
A process for removing metal from a solid material includes the steps of admixing the metal containing solid (10) with an aqueous liquid (26) and particles of ion exchange material (28) having a strong affinity for metal in a mixer (24), to form a slurry, allowing the slurry materials to interact, and removing the ion exchange material loaded with metal (32) from the solid.
