| Abstract: | An unique reduction process was proposed and tested for recovery of silver from its chloride. The reduction of silver chloride with ascorbic acid in the presence the aid of ammonia in low concentration was found to be fast at pH above 9 and complete recovery of silver is attainable with stoichiometric ascorbic acid within 10 min. |
