Resumo
Ion exchange resins have been used for many years for uranium, gold, and PGM (platinum group metals) hydrometallurgy. With the increasing worldwide demand for these and other high-value metals, as well as the need for processes with reduced environmental impact, ion exchange resin technology is expected to play an increasing role in mining and metals separations. This paper will provide a review of existing and new applications and industry trends. Despite the availability of a wide range of ion exchange resins for many years, the potential use of this technology has not been fully exploited. Ion exchange resins have however found a home in gold and uranium recovery, PGM recovery, purification, and separation, and for the recovery of metals from process streams, such as recovery of copper and vanadium from adipic acid manufacture and copper from printed circuit board manufacturing. In addition, new applications are being developed for recovery of gallium from aluminum leach liquors, for recovery of zinc from geothermal brines, and for the separation of cobalt from nickel. The various types of resins and processes used in these applications are reviewed.
