Story summary
- A University of Michigan-led study warns copper demand will rise from 23 million tons last year to 37 million tons by 2050.
- To meet this demand, copper prices must double from about $13,000 per ton to spur new mine developments, typically above $22,000 per ton.
- The researchers say recycling and lower-grade ores are insufficient.
- Co-author Adam Simon states faster mining approvals and public support are needed for timely copper production.
