Dust Suppression SAP

1. Mixing Ratio Manual for GelSAP CA‑150 in Dust Suppression

Based on the technical data sheet for GelSAP CA‑150 (superabsorbent polymer), the following guidelines optimize performance in different dust suppression scenarios. All ratios refer to weight of dry GelSAP per weight of water.

2. Stir at 300 rpm until clear (<3 min).
3. Add surfactant slowly under agitation. | Provides a uniform, low‑viscosity spray. Adjust concentration upward in windy areas. | | Mining Site (Roadways) | 0.5–0.8% | 99.2–99.5% | pH buffer to pH 6.5–7.0 | 1. Measure water and buffer, adjust pH.
4. Add GelSAP gradually while mixing at 400 rpm.
5. Continue stirring until fully dissolved (~2 min). | Higher loading improves adhesion on steep grades. | | Ore Handling Dust | 0.8–1.2% | 98.8–99.2% | Foam control agent 0.02–0.05% | 1. Inject GelSAP slurry into spray headers.
6. Maintain agitation to prevent settling. | Ensures controlled release and surface sealing. | | Stockpile / Bulk Material | 1.0–1.5% | 98.5–99.0% | Binder (e.g., lignosulfonate 0.5%) | 1. Pre‑mix binder into water.
7. Add GelSAP under high‑shear mixing.
8. Confirm viscosity <50 cP. | Forms a semi‑solid crust to prevent airborne dust. |

Notes:

• Temperatures below 10°C may slow dissolution; pre‑heat water if necessary.
• Always perform a small‑scale trial to fine‑tune for local soils and climate.
• Store mixed solution in sealed containers; use within 24 h for best results.

2. Application Case Studies & Customer Feedback

2.1 Road Maintenance Contractor (UK)

Challenge: Frequent dust complaints from residents along unpaved country lanes.
Solution: Applied GelSAP CA‑150 at 0.5% concentration with 0.08% surfactant.
Outcome: 70% reduction in visible dust within two weeks; extended watering intervals from daily to every 3 days.
Customer Feedback:

“GelSAP has significantly cut our water usage and complaints have dropped to nearly zero. The spray rigs handle the solution easily and maintenance costs are down.” — Operations Manager, GreenRoad Ltd.

2.2 Open‑Pit Mining Operation (Australia)

Challenge: Heavy equipment tracked dust onto public roads; regulatory fines imposed.
Solution: Deployed 0.8% GelSAP solution in water trucks; pH adjusted to 6.8.
Outcome: Dust plume virtually eliminated; compliance restored; water consumption down 40%.
Customer Feedback:

“The GelSAP treatment outperforms everything we’ve tried. Roll‑on/roll‑off dust has become a thing of the past.” — Environmental Superintendent, RedRock Mining Co.

2.3 Ore Concentrate Handling Terminal (Canada)

Challenge: Conveyor transfer points generated fine particulates, impacting worker safety.
Solution: Integrated 1.2% GelSAP dosing at transfer chutes; foam control added.
Outcome: 85% reduction in airborne particulates; operators report clearer visibility and fewer respiratory incidents.
Customer Feedback:

“Implementing GelSAP was straightforward and the results were immediate. Our health and safety team is very satisfied.” — Safety Manager, TrueNorth Terminals.
