Overview – In the mining industry, pH sensors are critical tools for enhancing operational efficiency, safety, and environmental compliance. These devices provide real-time data that empower mining operations to make informed decisions and mitigate risks.
Key Applications –
Tailings Storage Facilities
pH Monitoring in Tailings Water
pH data is crucial for the early detection and prevention of acid mine drainage (AMD), a process where acidic water mobilises heavy metals from waste rock. Preventing AMD safeguards surrounding ecosystems from contamination.
Stability Assessment
Monitoring pH variations helps assess the chemical stability of stored tailings, identifying potential instability. Early detection of risks helps mitigate leaks or spills.
Dam Wall Integrity
Sensors placed near dam walls can detect water ingress, an indicator of structural weakness. Early detection enables proactive maintenance, reducing the likelihood of dam wall breaches and associated environmental impacts.
Ground and Surface Water Monitoring
Environmental Monitoring
pH sensors track groundwater and surface water contamination, such as heavy metal leaching. This ensures regulatory compliance and protects ecosystems.
Early Warning Systems
Continuous pH monitoring provides early warnings of leaks or spills. This allows for rapid responses to minimise environmental damage.
Water Treatment and Waste Management
Process Water Treatment
pH sensors regulate neutralisation processes to ensure treated water meets discharge standards.
AMD Treatment
pH monitoring facilitates the treatment of AMD by controlling neutralising agents. This reduces contamination of local water sources.
Leaching and Metal Extraction
Heap Leaching
pH control optimises acid concentration for metal extraction, improving recovery rates and reducing chemical usage for metals like copper and gold.
CIL and CIP Processes
pH regulation in Carbon-in-Leach (CIL) and Carbon-in-Pulp (CIP) processes prevents cyanide decomposition. This maximises gold recovery and enhances safety.
