Understanding Residue Dams
Residue dams (also known as tailings storage facilities) are engineered structures used to store the waste materials generated during mineral processing. Given the nature of their contents, these dams require careful, ongoing management to ensure they remain safe and environmentally sound.
The Importance of Residue Dam Maintenance
Poorly maintained residue dams pose significant risks, including:
Structural failure and dam breaches — with potentially catastrophic consequences
Environmental pollution — leaching of heavy metals and chemicals into groundwater and soil
Community health risks — dust and chemical exposure to surrounding communities
Legal and financial liability — non-compliance with safety regulations
Regular, professional cleaning and maintenance is therefore not optional — it is essential.
Our Residue Dam Maintenance Services
Libubu Mining Group provides comprehensive residue dam maintenance services designed to maximise safety and extend facility lifespan:
Decant System Maintenance
We inspect and maintain decant towers, pipes, and associated infrastructure to ensure effective water management and prevent dam saturation.
Beach Management
Proper beach slope and width management is maintained to ensure structural stability. We apply engineered techniques to prevent overtopping and erosion.
Crest & Embankment Maintenance
Our teams regularly inspect and repair crests and embankments, addressing erosion, seepage, and deformation before they become critical issues.
Vegetation & Rehabilitation
Revegetation programmes are implemented on stable areas of the residue dam to reduce dust, control erosion, and promote long-term closure readiness.
Sludge & Slimes Management
We provide specialised sludge pumping, redistribution, and removal services to maintain optimal freeboard levels and storage capacity.
Monitoring & Reporting
Comprehensive geotechnical and environmental monitoring is conducted, with detailed reporting to support regulatory submissions and operational decision-making.
Regulatory Framework
Residue dam management in South Africa is governed by:
The Mine Health and Safety Act (Act 29 of 1996)
The National Environmental Management Act (NEMA)
The National Water Act
SANS 10286 — Code of Practice for Mine Residue
Libubu Mining Group ensures full compliance with all applicable legislation
