Mining & Metals
Water solutions & brine management for mining & metals
We provide comprehensive solutions for mining waters. We can help you to remove problem contaminants, treat mine waters, achieve minimal liquid discharge (MLD) or zero liquid discharge (ZLD), or recover valuable metals.
There is no single solution for mining waters. We will study your problem and present you with options.
IMPROVE FRESHWATER RECOVERY
We Understand Mining Waters
Mining locations are often remote. Mining waters are diverse, the volumes involved can be large, and they vary seasonally. Water issues that we can help with include:
- Selectively removing ‘problem’ contaminants from discharge
- Tailings pond capacity limits
- Effluent flows
- Meeting ion discharge limits (e.g. nitrate, sulfate, chloride)
- Recovering metal content (including heavy metal)
- Freshwater shortage/limits
- Groundwater treatment
- Mine dewatering
- Acid mine drainage

If you need to meet a sulfate discharge limit, we very likely have a solution for you. Every sulfate situation is different, so your sulfate challenge first deserves a dedicated review from our experts, to see how sulfates may be most economically treated using industrialized water treatment technologies.
Once a review is complete, most of our clients’ sulfate removal needs can be classified into high- and low- total dissolved solids (TDS) waters, described below. We have solutions for both, adjusted to your unique wastewater, including our new SulfateSelect solution family for low TDS wastewaters.
Water Management Options
The lowest cost treatment is to not treat at all. Our ScaleSense sensors measure problematic ions in real-time, helping you determine if you can avoid treatment. If you must treat, our IonSelect solution will selectively target and remove problem ions of concern, such as arsenic, cobalt, iron, and sulfates. IonSelect avoids over- or under-treating and can be more cost effective than treating the entire flow.
If you need more comprehensive treatment, our desalination and brine management solutions can help. XtremeRO is a robust ultra high recovery reverse osmosis system built for remote industries. BrineRefine partners with reverse osmosis to remove scaling ions, enabling maximum recovery and smooth operations. SaltMaker is a platform of evaporator-crystallizer solutions with four possible configurations depending on your site needs and energy sources.
Our treatment professionals will help you assess the cost and performance of relevant options. Contact us. Challenge us.

A lower cost evaporator crystallizer has emerged – the SaltMaker AirBreather. It is based on the robust backbone of its closest relative – the SaltMaker MultiEffect.
Recovering lithium in evaporation ponds can take a year or more and leaves behind lots of salt waste, but there are new technologies and processes that offer exciting options for lithium extraction.
Saltworks Technologies has been chosen to deliver two full-scale saline water treatment systems for a precious metals mine in the Canadian North. The zero liquid discharge (ZLD) plants will desalinate mine shaft water, and enable the site to achieve their treatment goals.
