Mining — Process Challenge

Process-Water Recycle Treatment for Mining

Treat and reuse process water with targeted coagulation, flocculation, and pH adjustment
Updated Jun 2026
Solution Approach

RawSource supplies the base chemicals that go into these programs. We can help with product selection, grade matching, and sourcing from multiple origins for supply security.

Typical Treatment Workflow
1
System Assessment
Characterize operating conditions — fluid composition, temperature, pressure, flow, and H2S/CO2/water cut — and benchmark current treatment performance.
2
Chemistry Selection
Match scale and corrosion inhibitors, biocides, or demulsifiers to the operating envelope, factoring compatibility, regulatory constraints, and downstream impacts.
3
Field Trial & Dosing
Determine treat rates through bottle and field trials, and configure continuous or batch delivery and packaging (drums, totes, ISO tanks) to logistics.
4
Monitoring & Adjustment
Track corrosion coupon/ER rates, residual inhibitor, and separator and water-quality performance, adjusting chemistry and dose as wells change.

Hydroxyethylidene Diphosphonic Acid
CAS 2809-21-4
Phosphate Esters & Derivatives
Common phosphonate antiscalant
Threshold scale inhibitor that keeps carbonate/sulfate scale from forming in recycled hard process water
Melting Point: 198-199   Boiling Point: 578.8   Solubility: 1.15e+01 g/L

2-Hydroxyphosphonocarboxylic Acid (HPAA)
CAS 23783-26-8
Phosphate Esters & Derivatives
Chelation / Sequestration
Its defining, well-documented property is chlorine/oxidant tolerance, unlike ordinary phosphonates. That is exactly why it belongs on a recycled-process-water page where the water carries residual biocide/oxidant while still needing carbonate scale and carbon-steel corrosion control. Genuine, use-case-specific fit.
Physical Description: Brown liquid. Slight acrid odor

Acrylic Acid-2-Acrylamido-2-Methylpropane Sulfonic Acid Copolymer (AA/AMPS)
CAS 40623-75-4
AA/AMPS copolymers are specifically valued for high calcium tolerance and stability at high hardness and temperature, dispersing CaCO3/sulfate and iron-oxide fines and keeping them suspended. These are precisely the reused/produced-water conditions, and it complements a threshold phosphonate. Genuine fit.

Bis(HexaMethylene Triamine Penta (Methylene Phosphonic Acid)) (BHMTPMPA)
CAS 34690-00-1
Premier low-dose inhibitor for barium/calcium sulfate scale. Sulfate scale (BaSO4/SrSO4) is the classic oilfield produced/recycle-water scaling problem that carbonate-focused inhibitors handle poorly, so this covers a distinct, on-topic failure mode rather than duplicating the carbonate chemistries. Genuine, distinctive fit.
