Treat Mine Impacted Waters or Recover Resources of Value

We provide modular, intelligent, and fully automated mine water treatment solutions engineered for reliable operations in demanding remote locations. Our solutions remove complex contaminants, recover valuable resources, and minimize or eliminate liquid discharge.

We Understand Mining Waters

Mining waters are diverse in composition, often high in volume, and can vary seasonally. Compounding these challenges, mining locations are often remote. Saltworks’ advanced solutions are engineered for reliable and economic use across the mining industry, including:

  • Mine or Mill Impacted Waters – Treatment and safe discharge to maintain production
  • Tailings Pond Water – Water recovery to reduce freshwater demand
  •  Groundwater Remediation – Removal of metals, sulfates, and organics
  •  Targeted Ion Removal – Selective removal of nitrate, sulfate, or chloride
  • Acid Mine Drainage – Neutralization and dissolved metals removal
  •  Saline & Brine Streams – Concentration for MLD/ZLD outcome
  • Resource Recovery – Extraction of valuable constituents from brines

Mine water is pretreated or filtered as needed and then passed through reverse osmosis (RO) to reject chlorides and other ions. RO brine volumes can be dialed to match water balance and brine storage needs or minimized through ultra-high recovery solutions such as FusionROOutput:RO permeate ready for remineralization and RO brine matched to site needs.  

Mine water is prefiltered via XtremeUF ultrafiltration, then treated with SelectNF nanofiltration to reject divalent ions (e.g., sulfates) and dissolved organics while allowing monovalent ions to pass. BrineRefine may be added for divalent ion precipitation, if needed.

Output: treated water with less divalent ions and reduced scaling risk  (partial TDS reduction, not full).

BrineRefine CSTR applies targeted chemical precipitation to remove ions of concern. XtremeUF filters out precipitated solids, producing clean water for downstream treatment. Output: Filtrate suitable for further processing or release; solids managed separately.

XtremeRO achieves high-pressure recovery of freshwater while concentrating brine. FusionRO pushes brine concentration up to ~200,000 mg/L TDS, reducing liquid waste by ~80% (varies by chemistry). Output: Significantly reduced brine volume for lower disposal cost.

SaltMaker MVR crystallizers evaporate concentrated brine, recovering the final water fraction and converting residuals into solid salts for safe disposal or reuse. Output: Distilled water + dry solids; no liquid discharge.

Modular, Automated & Factory Commissioned

Saltworks delivers modular, high-recovery water treatment systems engineered for cost-efficiency, reliability, and rapid deployment. Built and commissioned off-site, our fully automated solutions minimize operational disruption and excel in remote, demanding environments. Our advanced automation reduces operator intervention, while 24/7 remote monitoring, predictive analytics, and daily reporting optimize uptime, maintenance, and continuous performance.

How to Manage Brine Disposal & Treatment

The many options for managing brine, a term for saline wastewater from industrial processes, fall under two categories: brine treatment and brine disposal. Brine treatment involves desalinating the brine for reuse and producing a concentrated brine (lower liquid waste volume), or residual solids (zero liquid discharge).
