Energy efficiency in the mining sector
The mining sector is highly energy-intensive, and mining trucks are among the largest contributors to this consumption. These vehicles, used for transporting large volumes of material within open-pit mines, represent a significant portion of fuel consumption in mining operations, sometimes exceeding 30% to 40% of total energy use in certain mines.
Energy efficiency opportunities for mining trucks mainly lie in optimizing their operation, which includes implementing fuel management technologies, using high-efficiency tires, adjusting routes, and recovering energy during braking. The integration of fleet management systems and telematics technologies also enables real-time monitoring of vehicle behavior, optimizing fuel consumption and reducing emissions.
Additionally, the electrification of mining trucks is gaining ground as a long-term solution.
The use of electric or hybrid trucks can significantly reduce diesel consumption, as well as lower CO₂ emissions and associated operational costs.
Although still in its early stages, this technology is being implemented in some large mines to reduce their dependence on fossil fuels.
Regarding the overall processes in the mining plant, optimizing crushing, grinding, pumping, and ventilation equipment, along with waste heat recovery, remains a priority. Furthermore, cogeneration systems and the digitalization of energy data within the plants help reduce the total energy footprint of mining operations.
In conclusion, improvements in energy efficiency are not only key to cost reduction in mining but also enable greater operational sustainability, enhancing the competitiveness of operations and facilitating compliance with environmental regulations, particularly regarding CO₂ emissions.
