  • Copper Ore Types: Sulfides versus Oxides

    Apr 23, 2011Copper Ore Types: Sulfides versus Oxides. Sulfide copper ores are the most profitable ores because they have high copper content, and the copper can be more easily separated from the unwanted minerals. It is important to note that sulfide ores are not as abundant as the oxide ores.

  • What is the difference between gangue and ore?

    Answer Wiki. Gangue is valueless mineral associated with a valuable mineral that can economically be utilized, which is an ore . e.g. pyrite (FeS2) will be a gangue mineral associated with say sphalerite (ZnS) if the latter mineral can be utilized commercially; likewise, quartz/calcite will be gangue minerals associated with say an ore of copper.

  • How copper is made

    Most of the copper ores mined in the United States contain only about 1.2-1.6% copper by weight. The most common sulfide ore is chalcopyrite, CuFeS 2, also known as copper pyrite or yellow copper ore. Chalcocite, Cu 2 S, is another sulfide ore. Cuprite, or red copper ore, Cu 2 O, is an oxide ore.
