designed for effective recovery of aurocyanide complexes obtained from the alkaline processing of gold ores. tailored for recovery of precious metals from electroplating solutions,leaching solutions and seawater.ion exchange resins are commly used to remove trace levels and to concentrate precious metals such as uranium, gold, nickel,copper and other valuable metals.thje metals are then recovered by various specially regeneration techniques or by incineating the resin. recovery of the thenium and molybdenum from the sulfuric solutions whiuch solutions are very common in production of molybdenum and copper.
