Introduction to Mineral Processing or Beneficiation - Sepro Labs

Chalcopyrite does not in and of itself have any direct use as a mineral. Once chalcopyrite is concentrated (separated from the gangue), it requires further trewatment to extract copper via chemical (hydrometallurgical or pyrometallurcial) methods. A list of some valuable minerals is provided in Table 1.
