In Liddell’s Handbook of Nonferrous Metallurgy, Vol. 2, 1945, there is to be found a very complete account of the uses of chlorine as applied to the recovery of gold and silver, in Chlorination Processes & Methods. Introducing the chapter entitled “Chlorine Metallurgical Processes” Liddell says: Chlorine as a metallurgical agent appears to have lost ground during recent years, and much
Jul 18, 2013· Chlorination has been an important process step in the extraction of many nonferrous metals from their ores and concentrates. Some of the important chlorinating agents are gaseous chlorine, hydrochloric acid, ferric chloride, carbon tetrachloride and some alkali or alkaline chlorides like, NaCl, CaCl 2 and NH 4 C1. Because of their high reactivity at a moderate temperature, selectivity in

In tank-lixiviation of silver by chlorination, the extraction of the silver from chloridized ore by solutions of hyposulphite salts is performed by filtration.The ore-particles are kept stationary, while the solvent moves down through the mass of ore. The quickness of extraction, other conditions alike, is in direct proportion to the rapidity of the movement of the solvent through the ore.
Chlorination In Processing Gold Ore. what is the chlorination process for gold mining . gold ore processing plant These mining gold ore processing plants are virtually "plug and play"Ore processing is a 24 hour operation.

Power Generation: Stand up long term to the high pressures and corrosive chemicals commonly used by power plants. Semiconductor: Meet the high purity standards for cleanrooms and eliminate corrosion concerns caused by aggressive chemicals.
Alkali-acid and chlorination-roasting method can greatly improve the purity. However, the energy consumption is large and the equipment corrosion is serious, also the process is complex. Hydro fluoric acid method can remove the impurity W. Xie et al. / International Journal of Mineral Processing 155 (2016) 45–54 47.
Jan 01, 2016· To assist in overcoming these losses, chemical methods were quickly devised to extract gold from the mineral. Chlorination proved to be a successful lixiviant and quickly became popular as a treatment method, with most of the large independent mills around Cripple Creek mills using chlorine
