| titleOfInvention | Method for producing high purity reduced silver |
| abstract | (1) chloride leaching by adding hydrochloric acid and hydrogen peroxide to the depolarized anode slime;n n n (2) adding sodium carbonate to the chloride leaching residue;n n n (3) adding ammonia water to the residue (2);n n n (4) distilling ammonia to remove ammonia contained in the ammonia leaching solution of (3);n n n (5) washing with pure leachate to obtain silver chloride;n n n (6) converting silver chloride to silver oxide;n n n (7) A process for producing high-grade reducer silver, which consists of a process of converting silver oxide to silver, is known. In the present invention, to reduce the purity of the silver is characterized in that the following (a) to (d) performing the manufacturing process.n n n (a) performing dechlorination (2) using sodium carbonate at room temperature,n n n (b) the residue is washed with hot water after the dechlorination process;n n n (c) sulfuric acid is added instead of the distillation process (4),n n n (d) Re-run the chlorination process before step (6). |
