Mining activity entraps sand, ore particles and suspended solids in the water that flows from the stopes. The entrainment of solids in the mine’s process water threatens the effective operation of the mine’s underground water reticulation system.
Typical problems that occur include:
- The costly replacement of hydro-powered equipment and pumping infrastructure
- Silting of clarifiers, storage/intermediate dams and tanks
- Costly repairs of downstream infrastructure and processes when blockages occur
- Flooding of underground mining operations due to infrastructure failure
Good grit separation not only prevents problems in the mine water reticulation system, but the grit also has potential value as it usually contains extractable minerals of value.
Watercare Innovations has developed the Mobile De-Grit plant to remove solids from various process water reticulation systems.
Applications:
- Underground decline development dewatering
- De-gritting of mining run-off
- De-gritting pre-treatment for transfer dams
- De-gritting pre-treatment for clarifiers
- Any other grit-contaminated stream with a low solids content
Benefits:
- Rapid recovery of usable minerals
- Sustained life on downstream equipment and processes
- Low power consumption
- Compact footprint
- Low maintenance and abrasive wear
- Ability to accommodate fluctuating feed volumes
- Modular design allows the system to be easily expanded upon, by adding modules when required
- Semi- or fully automatic control available minerals
