Multotec’s metals recovery solutions for industrial water treatment use the Australian-based Clean TeQ’s Clean-iX® process to achieve higher resource recovery at lower cost. Used in the industry for over 50 years, it is built on the foundations of continuous counter-current ion exchange and is particularly suitable for metals recovery when working with base metals, gold, uranium, rare earth elements, scandium and other metals.
Metal extraction is achieved through the use of an organic solvent, ion exchange resin or adsorbent such as activated carbon. The Clean-iX® technology platform from Multotec targets the recovery and extraction of metals from pulps and solutions using ion exchange resins. The process is directly applicable to leaching, extraction and elution unit processes
Many valuable metals can be more effectively recovered through continuous ion exchange compared to conventional recovery routes. Clean-iX® offers the following advantages:
Clean-iX® technology is divided into metal extraction and elution.
Clean-IX® technology can be applied to clarified solutions and process slurries in mining applications. For slurries and pulps, Continuous Resin-In-Pulp (cRIP) enables the elimination of large solid-liquid separation circuits, reducing a plant’s capital and operating costs considerably.
Continuous Resin-In-Leach (cRIL), for leached slurries, combines leaching and extraction into a single stage. This process can significantly improve overall metal recovery and minimise the size of leaching/extraction circuits.
The Clean-iX® elution systems use a series of moving packed bed columns, each one performing a different step. Using individual columns for each unit process allows each column to be specifically designed for that function. For elution, two types of columns can be used.
