Lumwana Tailing Dam Expansion

The Lumwana Tailing Dam Expansion Project was undertaken to accommodate the growing volume of tailings generated by the Lumwana Copper Mine in Zambia. Tailings are the waste material left over after the extraction of valuable minerals from ore.

Key objectives of the project included:

• Extending Mine Life: Enabling the continued operation of the Lumwana mine by providing adequate storage capacity for the increasing volume of tailings.
• Environmental Sustainability: Ensuring the safe and environmentally sound containment of tailings to prevent potential environmental impacts such as water pollution and land degradation.
• Safety and Compliance: Adhering to strict environmental regulations and international best practices for tailings dam design and construction.

The project likely involved:

• Detailed Engineering and Design: Conducting thorough geotechnical investigations, designing the expanded dam structure, and developing a comprehensive environmental management plan.
• Earthworks and Construction: Excavating and moving large volumes of earth to create the expanded dam structure, including the construction of liner systems and drainage infrastructure.
• Environmental Monitoring: Implementing rigorous environmental monitoring programs to track water quality, air quality, and other environmental parameters throughout the construction and operational phases.
• Community Engagement: Engaging with local communities and stakeholders to address concerns and ensure transparency throughout the project lifecycle.

The successful completion of the Lumwana Tailing Dam Expansion Project has allowed the mine to continue operating while minimizing environmental risks and ensuring the long-term sustainability of mining operations in the region.
