Mining
separation, end to end.
Mining feeds are unforgiving. High suspended solids, high TDS, and reactive chemistry punish conventional membrane systems. Petro Sep's hydrophobic membrane portfolio handles tailings, brines, and process water without pretreatment cascades, with on-site pilot validation before capex.
What you get
Outcomes our customers see.
Specific to mining. Verified on real feeds. The numbers below come from commissioned projects, not data sheets.
- Lithium recovery from brine
- 98%
- Selective concentration of lithium chloride from continental brines, from sub-1% feeds.
- Tailings water recovery
- 95%
- Closed-loop recovery from tailings ponds, eliminating evaporator energy and freshwater draw.
- ZLD compliance
- Permit-ready zero liquid discharge systems for jurisdictions with mandatory discharge limits.
- Heavy metal rejection
- >99.9%
- Independently verified on copper, nickel, zinc, and cadmium feeds.
Applications
Where we deploy.
What we deliver.
The specific 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.
Application 04
Heap leach pregnant solution polishing
Membrane-based polishing ahead of solvent extraction or precipitation.
Technologies deployed
The right process for the fluid.
We pair technologies, not promote them. The choice depends on the chemistry, the volume, and the existing site infrastructure.
