ABSTRACT:
A method for the recovery of metal values from a solution by means of a cementation reaction in an oscillating container wherein the resulting cementate is converted by pyrometallurgical methods into molten metal and slag. In accordance with the present invention, at least a portion of the slag in particulate form is directed back into the oscillation reaction to serve as an agitation medium.
