In hydrometallurgy, the treatment of ores with water solutions, ion exchange resin helps to recover valuable metals like copper, silver, and gold from wastewaters. Uranium can be recovered from low-grade ores by leaching with dilute sulfuric acid—oxidizing if necessary to convert uranium(IV) to uranium(VI)—and then absorbing the negatively charged uranium sulfate complexions on a quaternary-base anion exchange resin. This highly selective absorption process thereby separates the uranium from iron and other metals. The uranium is later removed from the resin with dilute nitric acid.
