Book excerpt: Excerpt from Hydrometallurgy of Silver: With Special Reference to Chloridizing Roasting of Silver Ores and the Extraction of Silver by Hyposulphite and Cyanide Solutions The silver ores which are treated by a hydrometallurgical process are mostly complex sulphide ores consisting of quite a number of different metal sulphides. In order to render soluble the silver contained therein the ore is roasted with an addition of salt (chloridizing roasting), by which process the silver is converted into silver chloride. In this chemical reaction, however, all or nearly all the constituent minerals of the ore participate, which makes the process rather complicated and we may even say delicate, because the formed metal chlorides are volatile and induce the silver chloride to volatilize too, and in order to keep this loss at the minimum great care and skill are required. The solvent, whether this be sodium hyposulphite or concentrated brine, will extract all the silver which was converted into chloride, and the final result of extraction depends, therefore, entirely on the quality of the roasting. This being the case, it is obvious that chloridizing roasting is the most important part of the process, and that a metallurgist can not expect to be successful in the hydrometallurgy of silver unless he has a thorough knowledge of chloridizing roasting and the ability to apply skilfully this knowledge in actual practice. For this reason a large part of this treatise is devoted to the art of chloridizing roasting, which I consider to be especially necessary, as there is no new literature on this subject, though great advance has been made in it. Chloridizing roasting was originally studied and practised in relation to amalgamation. In amalgamation not only the silver amalgamates, but the base-metal chlorides also amalgamate, which greatly interferes with the process, causing a poor extraction, a great loss of silver and mercury, and the production of very base bullion.
