Bacteria found in mines are able to transform toxic copper ions to stable single-atom metallic copper.

Tahltan territory sits on an estimated 50.6 million ounces of gold and 12.5 billion pounds of copper.

The pace of the digital transition will impact the intensity in the use of energy, as well as direct demand for metals used in manufacturing, Fitch says.

Copper output was 82,042 tonnes, a jump of 46% from the same quarter a year earlier.

The expansion will help boost mill throughput to 1.8 million tonnes annually in the Boliden area of Sweden.

First production at Quellaveco project in Peru, which has the capacity to generate 300,000 tonnes of copper annually in its first 10 years of operation, is expected in 2022.

Metal recovery from recycling of lithium-ion batteries varies from 10% for copper to 80% for cobalt.
