The mining sector is under increasing pressure to improve energy efficiency as the demand for minerals throughout the world rises and technological developments accelerate. In 2025, optimising energy consumption in mining is no longer optional—it is imperative due to the global emphasis on sustainability, economic stability, and regulatory compliance [1].
To reduce energy costs in mining operations, several effective strategies can be applied ranging from technological upgrades to process optimizations and smart energy management. Key approaches include:
- Adoption of energy-efficient technologies such as electric haul trucks to replace diesel, energy-saving motors, drives, and control systems. This reduces fuel and electricity consumption and maintenance costs.
- Process optimization using AI and automation to monitor and adjust energy-intensive processes like grinding, flotation, ventilation, and haulage for maximum efficiency without sacrificing production output.
- Implementation of smart ventilation control, especially for underground mines, using IoT sensors to adjust airflow and fan operation based on real-time needs, cutting down significant energy used in ventilation.
- Use of renewable energy contracts, such as purchasing solar or wind power through long-term agreements that stabilize energy costs and reduce reliance on fossil fuels.
- Demand-side management strategies to reduce energy consumption during peak periods, balancing load and lowering peak demand charges.
- Recovery and reuse of waste energy, such as heat recovery and tailings water reuse for metal recovery, which reduce total processing energy.
- Continuous energy monitoring, automated control, and predictive maintenance enabled by IoT and AI to detect inefficiencies and optimize energy use in real time.
Together, these strategies can produce quick returns on investment, often within months to a couple of years, while significantly cutting operational energy expenses and carbon emissions, enhancing sustainability and profitability in mining operations.
