| Abstract: | The recovery of silver from scrap in an electronic pottery by separation technics was studied. The process condition were examined of HC1 concentration, bromine water addition, solution temperature and others. The feasibility was also studied to prepare silver nitrate with recovered silver. The experiment show that the recovery is simple and easy with silve nitrate up to industrial specification and the total yield of silver over 95 % . |
