Prelude to Atomic Energy (Feb, 1956)
Prelude to Atomic Energy
They’re moving mountains in South Africa. With the aid of Amberlite® ion exchange resins, sparsely distributed uranium is being selectively extracted from clay residues of gold mining. In Canada, on the Colorado Plateau, and in many other parts of the world, Amberlite resins are also easing the uranium refiner’s job.
The recovery of uranium is just one of the ways in which Amberlite ion exchange resins can serve in hydrometallurgy. Thorium and rare earth elements can be recovered from complex ores. Rhenium, relative of platinum, can be salvaged from refinery flue dusts. Dilute wastes from the conventional processing of cobalt and nickel can be scavenged for additional quantities of the metals. Even gold can be obtained from ores previously considered uneconomical to work.
Ion exchange, of course, is not restricted to hydro-metallurgy. Wherever ions in solution must be removed or replaced, ion exchange may provide the answer. The question is: what can Amberlite ion exchange resins do for you?
