Mining & Metals
Water solutions & brine management for mining & metals industries
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.
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 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.
BrineRefine is a continuous stirred tank reactor (CSTR) that executes diverse chemical reactions efficiently and with precision.
XtremeRO maximizes recovery & minimizes brine for tough industrial wastewaters. Our UHP RO delivers the highest recovery in the industry.
For many companies, water plays a critical role in ESG performance. With growing challenges and concerns around pollution, climate change, and consumption of energy, water, and chemicals, investing in responsible water management can measurably improve a company’s ESG profile while reducing operational risks.
Zero Liquid Discharge (ZLD) and Minimal Liquid Discharge (MLD) Become Lower Cost Through Reverse Osmosis Innovation
Saltworks is pleased to announce that recent advancements in reverse osmosis technology are now commercially available. Reduce conventional RO brine volumes by 50%, achieving brine concentrations of 130,000 to 150,000 mg/L TDS with spiral wound RO membranes.
Saltworks brings water mining expertise and advanced desalination technologies to our lithium clients, offering solutions for concentrating, refining, and converting low-grade lithium sources to battery-grade product. We offer higher purity and lower energy processing technology, that boosts yield, removes unit operations, and reduces cost.
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).
