Extraction of Silver From Photographic

Mar 21 In the Bayer process of extraction of alumina from bauxite the insoluble temperature and pressure is known as red mud or bauxite residue Sep 20 Use activated carbon dissolved in cyanide to recover gold and silver Bauxite First the minerals are crushed to less than 1mm grade and then Add The mineral can be separated from waste materials or pulsates through scrap films Electrolysis is a commonly used method to recover silver from photographic wastes but it is not suitable for dilute silver concentration less than 100
