Abstract
Gold and other metals in dissolved anionic form are removed from cyanide-derived aqueous mining effluent by passage of the effluent through an array of conduits in series connectivity, each conduit containing a stationary permeable bed of a particulate absorbent having selective affinity for dissolved anionic metal species, the flow of said effluent through said array being adjusted to produce sharply defined absorption zones.
