How Are Metals Extracted From Their Ores? | Reference

Full Answer. Copper ores generally contain sulfides or oxides and copper in the 0.5 to 2.0 percent range. Because of the greater value of copper metal, refining ores at these levels is profitable. Refiners crush copper sulfide ores mechanically and use froth floatation to bring copper-containing particles to the surface of a water solution.
