Reliable supply of minerals The Role of Critical Minerals

网页Production at today’s major copper mines has already peaked or is expected to peak in the early 2020s due to declining ore quality and reserve exhaustion. For example, the world’s largest copper mine, Escondida in Chile, appears to have reached a peak and its production in 2025 is expected to be at least 5% lower than today.

Copper ore density separations by float/sink in a dry

网页2013年6月10日In the case of the EH ore, it appears that if a separation were made at about 3300 kg/m 3, about 25% of the mass could be removed before grinding which would contain little copper. For the ARC-1 ore, one could conceive of a separation at 2350 kg/m 3, which would remove about 50% of the feed ore mass as gangue which contains very
