Beschreibung
Zusammenfassung:	The present invention is directed to a process for removing various contaminants (e.g., organic collectors, contaminant metals or spectator ions, and/or suspended and colloidal solids) from process streams in leaching processes. 'Me contaminant removal is performed by one or more membrane filtration systems (22) (e.g., nanofilters, ultrafilters, and/or micro--filters) treating process streams including, the pregnant leaching solution (18), the barren raffinate, and the lean and rich electrolytes.
