Mine Water Treatment Plant Design
Project Overview
Integrated Sustainability designed a mine water treatment plant with a 390 m3/h capacity to remove metals and selenium. Advanced sludge removal, ion exchange, and filtration technologies were employed. The project design was developed to maintain discharge criteria, supporting sustainable water management throughout the mine’s operational and closure phases.
Project Deliverables
- Designed plant to remove dissolved metals (Al, As, Cd, Cu, Zn, Fe) and selenium at multiple oxidation states.
- Plant design capacity = 390 m3/h.
- Major Process Equipment: High-Density Sludge Metals Removal Treatment Ion Exchange Unit + Electro Reduction Unit, Reagent Dosing, Process Tanks, Clarification Unit & Multi-Media Filtration, Filter Press (Sludge Dewatering)
- Process selection, engineering, 3-D plant modelling, and advanced thermodynamic aqueous chemistry modelling with multivalent ion separation software.
- Analyzed multiple feed water sources resulting in a phased treatment approach due to expected mine water acidification during closure and post closure.
- Provided NI 43-101 Qualified Person signoff on feasibility study.
- Delivered with BQE Water (BQE ion exchange/electro-reduction technology developer).
