- Energy Efficiency
-
Mining and mineral processing supports some of the biggest structural trends globally, and plays a crucial role in transitioning to net zero emissions.
Comminution is responsible for at least 40% of total energy use in mining and mineral processing, but there is significant potential to reduce energy costs through applying energy-efficiency strategies to comminution. Additional opportunities for energy savings exist in other areas including:
- blasting and sorting
- dewatering
- froth flotation separation
- materials movement
- ventilation
