Clean iX® (Metals Recovery)
Ensuring reliable water supply, at the lowest possible cost, is a critical operational requirement in mines and mineral processing plants.
To help miners and process plants meet these requirements, Multotec offers a proven range of mine water treatment technologies to improve their water performance, compliance and security.
Developed and optimised in partnership with mining customers around the world, Multotec’s modular continuous counter current ion exchange and ionic filtration technologies deliver improved metals recovery through more efficient chemical precipitation efficiency and performance.
Treating mine water involves the removal of hazardous dissolved substances and suspended solids, including cyanides, arsenic, sulphates and toxic heavy metals with maximum cost-effectiveness and lowest ecological footprint.
Continuous counter-current ion exchange combines the high resin efficiency, minimised resin inventory and higher concentration capabilities of continuous ion exchange with the maximum reaction driving force for highest, selective recovery of counter current ion exchange.
The results is the most efficient form of ion exchange available on the market. This means lower costs and improved performance of your water treatment cycle:
Multotec ion exchange solutions are ideal in treating mine water and recovering minerals across a wide range of applications:
Ion exchange resins are typically the most expensive item in ion exchange applications. That’s why our resins are designed for maximum efficiency and reuse. We will work with you in selecting the most appropriate resin for your application depending on your process condition, including:
From water sampling to lab-scale test work, Multotec help you lower your plant’s operating costs.
Multotec offer clients a two-stage, 1 m3/hr test rig, which can be assembled on-site for water testing and optimisation.
We offer resin screening, IX kinetics, equilibrium isotherm and column loading & elution tests as part of our lab services.
Our 1 m³/hr, 2-stage test rig for piloting Clean-iX / CIF® technology applications.
Our ion exchange technology is highly effective in scavenging toxic heavy metals and can remove over 99.4% sulphate content of acid mine water, helping to prevent ground and surface water pollution from mines.
A single CIF® system can extract acid from the water, producing neutral water for discharge. The increase in pH by the system causes several elements to precipitate, providing further water purification. This is possible through in-column precipitation and solids handling.
If the resultant TDS of the product water is too high, the CIF® system can be replaced by a DeSALx® system. CIF®/DeSAlx® can also be used in conjunction with a precipitation step, which incorporates a brine treatment process and can help work towards zero liquid discharge (ZLD).
