Cut Off Grades Explained…How does declining ore grade affect a copper mine?The main impact of declining ore grade is on the direct environment of copper mine ( Table S7 ). There will inevitably be increased production of tailings, which can leach out into the runoff after mixing with rainwater and affect human health. To reduce this impact, further comprehensive recycling of tailings is required.

Assessing the future environmental impacts of copper production in

…Does a declining quality of copper ore affect environmental performance?The declining quality of copper ore appears to be a key factor on increasing environmental performance, with the assumed decline driving up energy use by more than the gains from the assumed improvement in energy efficiency.

Assessing the future environmental impacts of copper production in

…Does declining ore grade lead to a supply constraint?However, the oft-discussed declining ore grade and, therefore, the assumed enormous increase in energy demand and global warming potential could lead to a supply constraint. To develop suitable strategies to ensure copper availability, it is important to better understand the relationship between energy and ore grade and also its development.
