  • Copper recycling and sustainability

    Recycling copper uses much less energy, about 10GJ/tonne, that's only 10% of the energy needed for extraction. This energy saving leads to the conservation of valuable reserves of oil, gas or coal and reduces the amount of CO 2 released into the atmosphere. Conservation of copper ore To date only about 12% of known copper resources have been mined.

  • Bacteria from a Brazilian copper mine work a striking

    Apr 23, 2021The so-called monoatomic metallic form of copper is 170 to 179 picometers in size. Producing this kind of copper in the lab is laborious, costly and requires toxic chemicals. Copper in general is a good conductor, but the [monoatomic copper] that these microorganisms are producing is very versatile because it is the pure form, Rodrigues said.
