Abstract
An ion exchange compound in a fluid organic carrier is cycled between mixing and separating from a weak acid stream and a strong acid stream. The weak acid stream is cycled between directly contacting ore to chemically dissolve metal and exchanging the metal for hydrogen ions of the exchange compound. The strong acid stream is cycled between exchanging its hydrogen ions for the metal bonded to the exchange compound and yielding the metal to a recovery system. The mixing and separation of the organic carrier with the two acid streams is by a pump, an electric field and a centrifuge.
