How to Recover Silver from Nitrate Solutions

2016-3-24  The solution should be well mixed and stirred together, for the clots of silver chloride retain some nitrate. The precipitate should then be allowed to settle, and the clear solution decanted off, and, if necessary, run through a filter. The silver chloride is then washed with water until the washings are neutral. It is then reduced by zinc or iron.
