In addition to water molecules the coordination chemistry of leaching generally involves simple inorganic anionic ligands, ammonia, or acetonitrile. Many of the well-established processes (see Table 2) were considered in CCC (1987),4 and are also described in a recent comprehensive text on hydrometallurgy.2... 

Volatile weak electrolytes, such as ammonia, carbon dioxide, and hydrohydrogen sulfide are of great interest in hydrometallurgy. The vapor-liquid...
