Smarter mine water management with ResMix
As the mining sector intensifies its focus on operational resilience, environmental compliance and sustainable site closure, water quality within dams, storages and tailings ponds has never been more critical.
Whether it’s raw water, process water, tailings supernatant, sedimentation basins or environmental buffers, the risk of thermal stratification, dissolved metal contamination and toxic blue-green algae is a challenge common to mine sites across Australia.
That’s where WEARS Australia’s ResMix systems delivers transformative value. Built on decades of in-field testing and rigorous hydrodynamic research, ResMix is a surface-mounted axial flow impeller system designed to destratify and homogenise large water bodies efficiently and economically.
Smarter mixing, measurable impact
Unlike compressed-air or bottom aerators that stir nutrient-rich sediments, ResMix uses top-down circulation to push oxygenated surface water to depth. The results are immediate and measurable:
- Dissolved oxygen lift: Deployments have shown DO increases from near-zero to over 4.0mg/L within days, breaking down anoxic layers across full depth columns.
- Metal control: Soluble manganese and iron levels have dropped by over 50% in short timeframes, helping to mitigate staining, odours and downstream treatment burdens.
- Algal suppression: Long-term operation has eliminated cyanobacterial blooms by removing cells from the euphotic zone, promoting biologically stable conditions.
Designed for harsh mining conditions
Mining water assets are dynamic and often nutrient-loaded. ResMix is engineered to perform in this environment:
- Low energy draw (3–8kW) and up to 15,000L/s throughput, depending on model.
- Floating pontoon design: ideal for supernatant ponds, tailings dams, sedimentation reservoirs or active process storages.
- Minimal maintenance and full integration with SCADA or remote-control systems.
- Suitable for use in conjunction with mine closure plans, water treatment plants or on-site reuse schemes.
Data-backed performance
WEARS has compiled over 20 years of destratification studies from a wide range of Australian and international sites. Independent research confirms ResMix’s ability to:
- Deliver oxygenation deep into water columns at a fraction of the cost of legacy systems.
- Maintain uniform thermal profiles over distances exceeding 300m from a single unit.
- Reduce blue-green algae counts by more than 90%.
Compliance, ESG and closure alignment
By enhancing in-storage water quality, ResMix reduces reliance on downstream chemical treatment. It supports compliance with ANZECC and site-specific water guidelines while reducing the risk of downstream pollution, odour complaints and process disruptions. For closure planning, maintaining oxic conditions in pit lakes and tailings storages aligns with sustainable final landforms and stakeholder expectations.
A scalable solution for all stored water challenges
Whether you’re managing drinking water, recycled effluent, pit lakes, dust suppression dams or site runoff storages, ResMix is your frontline defence against degradation, odour, metals and stratification. If you manage stored water, ResMix can help you manage it better.
