- Modular and mobile
- Self-cleaning
- High solids handling capabilities
- Achieve zero liquid discharge
- Robust, with the ability to operate in high scaling and fouling conditions
- Optimised resin inventory

 

 Benefits of CIF® in your solid/liquid separation operation

  • High water recovery
  • Reduced brine production
  • Reduced chemical consumption
  • Reduced maintenanced
  • Smaller plant footprint
  • Lower capital and operating costs

The role of Clean-iX® in solid/liquid separation

Test Work Capabilities

Clean-iX® for solid/liquid separation is built on the foundations of continuous ion exchange technology. The Clean-iX for metals recovery process uses the principles of continuous counter-current ion exchange, providing you with highly-efficient and cost-effective extraction, concentration and solid/liquid separation processes.


Clean-iX® is tailored for recovering, among others, gold, uranium, rare earths and base metals and makes use of Continuous Resin-In-Column (cLX) for extraction from clarified leach solutions; Continuous Resin-In-Pulp (cRIP) for extraction from leached pulp; Continuous.

 Leading design innovations for reliable, efficient solid/liquid separation.  

Optimised separation industrial centrifugal decanters

Multotec’s industrial centrifugal decanters enable fast and accurate centrifugation in mineral processing. They operate on the counter-flow principle. Suspension is introduced to the centre of the bowl for separation. Sediment is then conveyed via the scroll, which continuously rotates at an altered speed to that of the bowl, resulting in clarified liquid flowing from the bowl’s large diameter opening.

The range includes the TS Industrial Decanter Centrifuge, DZ Industrial Decanter Centrifuge and DZS Screen Decanter Centrifuge. All of these centrifuges:

  • reduce thermal drying and other processing costs
  • increase separation efficiency for particles of all sizes
  • have a compact design that facilitates use in small operating areas
  • reduce waste with optimised separation

 Multotec supports your requirements for customised solid/liquid separation equipment.
