<p>A recovery method for base metal values (e.g. copper) from ore slurry or aqueous solution, comprising forming a solution of a metal complex (e.g. cyano-copper) having an affinity for adsorption sites on activated carbon, adsorbing the metal complex onto activated carbon, and stripping the adsorbed metal complex by forming a reaction product with said metal complex, the reaction product having no affinity for adsorption sites on activated carbon. A method for recovering base metals and noble metals separately from an ore containing both is also disclosed. The method is carried out in an apparatus comprising a leaching stage (17) and an adsorption stage (221) which may be combined, and an elution column (11). The method and apparatus also provide a mechanism for recovery of activated carbon and cyanide.</p> |
