  • Copper extraction - Wikipedia

    When rich enough, native copper ore bodies may be treated to recover the contained copper via a gravity separation circuit where the density of the metal is used to liberate it from the lighter silicate minerals. Often, the nature of the gangue is important, as clay-rich native copper ores prove difficult to .

  • Innovations: Introduction to Copper: Mining & Extraction

    The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfur-bearing volcanic magmas, which have separated into metal sulfides and siliceous melts.
