Application 01
Lithium brine concentration
Energy-efficient evaporation alternative for lithium producers in South America, China, and North America.

Mining
plants and separation, end to end.
Mining sites need both heavy fabrication and tough separation. We build the process plants, vessels, and skids that go around the recovery train, and we bring our own membrane IP for the feeds that punish conventional systems. Tailings concentration, lithium brine recovery, acid mine drainage, and zero liquid discharge, engineered, fabricated, piloted on-site, and operated.

What we deliver.
The specific scopes and separation problems we solve for mining operators.
Application 02
Acid mine drainage treatment
Recovery of clean water and isolation of metal sulfates for resale or compliant disposal.
Application 03
Tailings water recycle
Closed-loop systems that return process water to the head of the mill, eliminating freshwater draw and tailings dam pressure in equal measure.
Application 04
Heap leach pregnant solution polishing
Membrane-based polishing ahead of solvent extraction or precipitation.
Application 05
Reverse osmosis reject brine concentration
VMD takes RO reject from 6 to 8% TDS up to 25%+, leaving 25 to 30% less concentrated brine for disposal and making ZLD economic.
Fabrication scope
What we build for this sector.
Mineral and hydrometallurgy plants involve heavy vessels, structural scope, and process piping. We build the recovery train, the supporting equipment, and the membrane systems for the difficult fluids, under one contract.

Membrane technologies
The right process for the fluid.
Mining feeds rarely fail in one place. The chemistry, the solids loading, and the climate all conspire. We typically pair a vacuum membrane distillation front-end (AQUA-SEP®) with crystallization at the back-end for ZLD compliance.
VMD
Vacuum Membrane Distillation
High-recovery treatment for high-salinity and complex feeds where reverse osmosis cannot go.

MD
Membrane Distillation
Thermally driven separation for fluids that defeat conventional distillation.
Learn more
ZLD
Zero Liquid Discharge
Closed-loop systems that recover water and isolate solids for industrial wastewater.
