Extraction Of Silver - Mineral Processing Metallurgy

2017-1-10  Extraction of Silver After a chloridizing roasting the ore should be examined to ascertain the amount of chloride of silver contained in it, according to 21. In case the extraction should not be satisfactory, it is then easier to find what the cause is. The ore is then prepared for leaching.

Recovery of Silver, Gold, and Lead From a Complex

combined FeC13-NaCl leach solution. Because both lead and silver were solubilized, silver recovery from high-silver ore would be difficult. Similar methods were used by Scheiner (8-10) to extract silver and other metals-from a complex sulfide concentrate. These methods required a C12-02 or FeC12-02 leach at elevated pressure and temperature to form insoluble lead and silver chlorides, which were then
