Why It Matters
Chemical binders and surfactant sprays for fugitive dust control at mine sites
Solution Approach
Chemical binders and surfactant sprays for fugitive dust control at mine sites 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 rates—and benchmark current treatment performance.
2
Chemistry Selection
Match base chemicals to your operating envelope. Factor in compatibility with existing programs, regulatory constraints, and downstream impacts.
3
Dosage & Delivery
Determine optimal treat rates through jar testing or field trials. Configure packaging (drums, totes, ISO tanks) to match consumption and storage logistics.
4
Monitoring & Adjustment
Track KPIs—coupon rates, residuals, separator performance, water quality. Adjust chemistry and dosage as conditions change.
Recommended Chemistries (4)
Calcium Chloride
CAS 10043-52-4
Specialty Additives
Viscosity Modification
Deliquescent calcium chloride absorbs atmospheric moisture to keep the road/stockpile surface continuously damp, binding fines and suppressing fugitive dust far longer than a plain water spray
Melting Point: 782 °C Boiling Point: 1935 °C Density: 2.15 at 20 °C

Magnesium Chloride
CAS 7786-30-3
Specialty Additives
Viscosity Modification
Magnesium chloride is the other canonical deliquescent dust-control salt; it pulls humidity into the surface layer to hold fines together, effective at lower temperatures/humidity than CaCl2
Physical Description: Liquid; Water or Solvent Wet Solid; Dry Powder;… Appearance: Thin white to gray granules and/or flakes Boiling Point: 1,412 °C

Sodium Lauryl Sulfate (SLS)
CAS 151-21-3
Surfactants
Cleaning / Degreasing
Wetting surfactant that breaks water surface tension so spray penetrates and agglomerates fine dust
Melting Point: 204–207 °C Density: > 1.1 at 20 °C Solubility: < 1 mg/mL at 19 °C

Polyacrylamide Flocculant
CAS 9003-05-8
Polymers & Resins
Primary flocculant backbone
Can act as a soil/surface binder that crusts and holds fines on haul roads and stockpiles
