METHOD FOR REMOVING CONTAMINANTS FROM PROCESS STREAMS IN METAL RECOVERY PROCESSES |
| 摘要 |
<p>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. The contaminant removal is performed by one or more membrane filtration systems (22) (e.g., nanofilters, ultrafilters, and/or microfilters) treating process streams including, the pregnant leaching solution (18), the barren raffinate, and the lean and rich electrolytes.</p> |
