Silver processing Britannica
Because of the much lower value of silver scrap, recycling techniques applicable to gold (e.g., cyanidation of lowgrade scrap) are uneconomic for silver. Lowgrade silver scrap is instead returned to a smelter for processing. Assaying. The fire assaying techniques described above for gold are equally applicable to silver. In order to determine
