Japan’s Mitsubishi Corporation has an-nounced it raised its stake in U.S. natural resources company Jetti Holdings which has “developed a cutting-edge, catalytic technology that allows for effective extraction of copper from primary sulfide ores,” the group said in a statement.
“With global efforts to decarbonize intensifying, demand is on the rise for copper, a material that it vital for growth in electric vehicles and renewable energies. Unfortunately, this rise in demand is depleting copper resources and forcing mines to produce more low-grade ore,” according to the statement.
The value of the latest investment was not disclosed.
Jetti Holdings says the “technology enables heap and stockpile leach extraction of copper trapped in primary sulfide ores, which are usually discarded due to their low copper yields being insufficient to justify traditional processing methods” and it has „already confirmed the commercial-scale effectiveness of its technology through its trial ap-plication at the Pinto Valley copper mine in Arizona.”
