The resin used in the CLEAN-IX® process can be selected to target the required metal ions, adsorbing them onto the resin which is then treated further for recovery. For more information about metal recovery, see our metal recovery page.
The base technology for the CLEAN-IX® process was developed by the All Russian Research Institute of Chemical Technology (ARRICT) over a period of 40 years. Since 1951, ARRICT has been involved in the development of over 30 mining operations using the technology, mainly for uranium and gold extraction, from leached slurries and solutions.
CLEAN-IX® covers the complete spectrum of leach systems (both acid and alkaline), using the following technologies; Continuous Resin-In-Column (CLX) for clarified leach solutions (<4% solids), Continuous Resin-In-Pulp (CRIP) and Resin-in-Leach (CRIL) for slurries (4-50% solids), and Continuous Elution (U-Column) for metal elution and purification.
