    1 天前 · Copper is one of the oldest metals ever used and has been one of the important materials in the development of civilization. Because of its properties, singularly or in combination, of high ductility, malleability, and thermal and electrical conductivity, and its resistance to corrosion, copper has become a major industrial metal, ranking third after iron and aluminum in terms of quantities consumed.

  • Copper Ore an overview ScienceDirect Topics

    Copper is among the few metals known to ancient civilizations. Copper, gold, silver, platinum, and meteoric iron are the only metals found in their native state. However ∼90% of copper comes from sulfide ores. Most copper ores contain 0.5% Cu or less, iron being the principal metallic impurity. The ores are ground to a fine powder and concentrated (normally by floatation) to 20–25% Cu.
