ABSTRACT:
The present invention is concerned with a process for selectively removing antimony, bismuth, or both, from acidic solution by submitting the solution to oxidizing conditions thereby causing the selective precipitation of antimony and bismuth; filtering precipitated antimony and bismuth; and submitting the oxidized solution to reducing conditions before it is returned to the electrorefining cell.
