• Innovations: How Do They Do That? How Copper is Made

    Copper ore, in concentrations ranging from 0.29 percent to ten times that amount, is mined from open pit or underground mines. The crushed mine ore is ground in rod and ball mills and then sent to flotation machines where the copper mineral rises to the top in a froth, making a copper concentrate of approximately 30 percent, 27 percent iron and 33 percent sulfur.
