Mining
Dyvar® Technology offers a proven and modular solution for reducing or dewatering disposal (brine or evaporation) pond volumes, recovering water, supporting extraction processes and removing salts, particularly where conventional technologies, and natural evaporation ponds fall short.
Mining processes demand large volumes of fresh water, often resulting in highly contaminated, complex wastewater with hypersaline brines. Often these brine streams contain valuable minerals for recovery. These complex brines, generated from extraction processes, mine tailings management, return water flows, pollution control dams, or general mining-impacted waters, are increasingly subject to environmental regulation and disposal challenges.

Future-Proof Brine Management in Mining
Mining operators across coal, gold, platinum group metals, copper, as well as base metals, lithium, potash and others, can face brine management challenges.
Long-term brine management can be significant in mine-closure planning. By evaluating future approaches such as selective salt recovery, brine by-product beneficiation, brine pond minimization, and beneficial water recovery, mining operators can reduce long term closure liability and reduce environmental and social risks in mine-affected communities.
Two key applications in mining
Mine-impacted waters (e.g. Acid Mine Drainage, Trickling Water, Tailings water)
Water from underground seepage, tailings recovery, mineral processing, or oxidation of sulfide ore bodies (e.g., Acid Mine Drainage – AMD) has to be treated, often ending up in a treatment plant involving high-recovery Reverse Osmosis (RO). After treatment with Reverse Osmosis (RO), a concentrated and complex brine stream remains and is often stored in evaporation ponds. Brine produced by (ultra-high) recovery RO includes concentrated salts, organics and other contaminants that make traditional recovery techniques difficult. Dyvar® can be used to further concentrate these RO brines, producing fresh water (recovering water), reducing volume, reducing disposal costs and minimizing environmental impact.
Mining Extraction Processes (e.g. Direct Lithium Extraction)
In processes such as direct lithium extraction, Dyvar® enhances operational performance by:
- Increasing the lithium concentration in the mother liquid
- Recovering reusable water
- Removing unwanted salts
A smarter way to treat high-TDS brines
Salttech’s Dyvar® Technology is a one-step concentration and crystallization system designed for highly concentrated and variable brines. It operates electrically (no continuous steam supply required), is modular and containerized or skid based, and is capable of processing complex brines with high TDS, extremely low or high pH, and organic loads.
High water recovery with minimal waste
Achieves MLD to ZLD by reducing brine volume while supporting compliance with environmental regulations.
Handles complex brines with ease
Operates reliably with organics, extreme pH ranges, high TDS, and removes primary salts.
Boosts resource recovery
Enables higher lithium concentration, improving extraction efficiency and overall recovery value.
Flexible and easy to deploy
Available as modular, mobile, or skid-based plug & play units for quick integration.
