Process Water Treatment Industry

Water plays a vital role in the overall operations of a mineral processing plant, and any supply issues can have massive impacts on your production uptime.

Multotec offers a complete range of process water treatment technologies and expertise to ensure optimal, cost-effective and compliant water usage on ore preparation or industrial plant.

Our solutions optimise the entire plant water cycle, from feedwater (underground, borehole or municipal bulk supply), recirculation of process water and discharge water. We ensure treatment requirements are met at each stage, allowing operations to focus on core production activities.

Multotec offers complete process water treatment solutions with extensive experience in:

  • Continuous counter current ion exchange (CIF®) plants
  • Membrane technology plants
  • Precipitation and clarification plants
  • Cyanide detox plants

In addition, Multotec offers:

  • Ancillary equipment (pumps, screens, filter presses, etc.)
  • Test work services
  • Aftersales & technical support

Whether you need a secure, cost-effective water supply, recovery of saleable minerals or are working towards Zero Liquid Discharge (ZLD), Multotec has the technologies and expertise to meet your requirements.

Our Water Treatment Solutions:

HiROx® Technology

A highly efficient, minimum-discharge water treatment process combining CIF® and ultra-high-recovery reverse osmosis (RO).

CIF® for Process Water Treatment

CIF® for Process Water Treatment

Continuous Ionic Filtration from Multotec provides the ability to achieve high water recoveries at lower capital and operating costs.

Clean-iX® for Metals Recovery

Metal recovery is achieved through solid liquid separation and mine water treatment.

Clean-iX for metals recovery combines efficient forms of extraction with the best resin, providing an optimum solution for metals recovery.

Benefits of our process water treatment solutions:


Multotec, in collaboration with strategic technology partners such as Clean TeQ, a world leader in metals recovery and industrial water treatment, provides leading solutions for continuous counter current ion exchange plants.

A continuous ion exchange system offers the following advantages:

  • A reduction in reagent consumption & the associated operating cost
  • Optimised resin use for significant cost savings on CAPEX
  • Lower OPEX due to the counter-current configuration of solutions & resin which enables more complete exploitation of the resin’s full loading capacity & selectivity
  • Effectively accommodates fluctuations in feed grade
  • Selectively recover valuable, saleable trace by-products
  • Reduced downstream processing requirements – concentrated lower volume eluate
  • Tolerance potential to suspended solids breakthrough from upstream solid-liquid separation unit operations& resilience to bed fouling
  • Low maintenance with minimal operator requirements or intervention

Lowering your resin inventory costs

The resin used in ion exchange is typically the most expensive cost in ion exchange applications, and so maximising resin use and efficiency is a primary concern in process water treatment. 

By using state-of-the-art continuous ion exchange technologies, Multotec delivers enhanced resin efficiency and minimised resin inventory, while producing higher concentration of product solutions. The counter current configuration provides maximum reaction driving force for increased recovery as well as highly selective recovery of target metals. This enhances the efficiency of the ion exchange plant.

Multotec will work with you to select the most appropriate resin for your application depending on your process condition.

Multotec has achieved total water costs of R8/kL on mineral processing plants.


Services & Test Work

From water sampling to lab-scale test work, Multotec support your requirements to constantly lower the operating costs of your plants.

On-Site Test Work

Multotec offer clients a two-stage, 1 m3/hr test rig, which can be assembled on-site for water testing and optimisation. 

Laboratory Test Work 

We offer resin screening, IX kinetics, equilibrium isotherm and column loading & elution tests as part of our lab services.

 

Lowering your environmental footprint:

Our treatment solutions can achieve high water recoveries of up to 97% with Continuous Ionic Filtration® (CIF®), and low brine volumes. This technology can be used by plants working towards Zero Liquid Discharge (ZLD) while reclaiming valuable minerals to lower overall waste. As such, we’re helping plants become more sustainable while lowering water usage.

The modular and containerised nature of our ion exchange solutions allows for water treatment in the most remote locations.
