Mining Environmental Challenge

Mining operations face increasingly stringent environmental regulations governing water discharge. Compliance requires effective treatment for suspended solids, pH control, metals removal, and other parameters specific to mining wastewater characteristics.

Permit Requirements

Discharge permits typically specify limits for TSS (<30-50 mg/L), pH (6-9), metals (Cu, Zn, Pb, Cd), and other parameters. Non-compliance can result in fines and operational shutdowns.

Water Chemistry

Mining water varies widely in composition depending on ore type, processing methods, and site geology. Treatment must address site-specific contaminants including acids, metals, and process reagents.

Monitoring & Reporting

Regulatory compliance requires continuous monitoring, data logging, and periodic reporting. Automated systems with SCADA integration simplify compliance documentation.

Sustainability Goals

Beyond compliance, mining companies increasingly pursue sustainability targets including water recycling, zero discharge, and net-positive environmental impact.

Compliance Applications

Process Water Discharge

Treatment of excess process water for discharge to surface waters, meeting permit limits for suspended solids, pH, and other parameters.

Mine Water Discharge

Treatment of dewatering water from pit and underground operations including pH correction and metals removal before environmental release.

Acid Mine Drainage

Specialised treatment for acidic water containing elevated metals, requiring neutralisation, precipitation, and solids removal.

Tailings Seepage

Collection and treatment of seepage from tailings facilities to prevent groundwater contamination and meet discharge requirements.

Stormwater Runoff

Treatment of contaminated stormwater from process areas, stockpiles, and haul roads before discharge to receiving waters.

Zero Discharge Systems

Closed-loop water management systems that eliminate discharge through high-efficiency water recycling and evaporation.

5-Step Compliance Treatment Process

1

Pre-Treatment

Screening and grit removal protect downstream equipment and remove coarse solids from mine water.

2

pH Adjustment

Neutralisation of acidic or alkaline water using automated chemical dosing systems to achieve pH 6-9 for discharge.

3

Metals Removal

Chemical precipitation and flotation to remove dissolved metals including copper, zinc, lead, and cadmium.

4

Solids Separation

Clarification and filtration to achieve required suspended solids levels for discharge or reuse.

5

Monitoring

Continuous monitoring of pH, flow, and turbidity with data logging for regulatory reporting and permit compliance.

Recommended Equipment

LAMELLA Separator

High-rate clarification for suspended solids removal with compact footprint ideal for remote mine sites.

Permit Compliance

DAF Systems

Dissolved air flotation for metals precipitation and fine solids removal achieving low discharge concentrations.

Metals Removal

Self-Cleaning Filters

Final polishing filtration to ensure consistent compliance with suspended solids discharge limits.

Consistent Quality

Chemical Dosing
