  • Mineral processing | metallurgy | Britannica

    Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy.

  • Copper extraction - Wikipedia

    Most copper ores contain only a small percentage of copper metal bound up within valuable ore minerals, with the remainder of the ore being unwanted rock or gangue minerals, typically silicate minerals or oxide minerals for which there is often no value. In some cases, tailings have been retreated to recover lost value as the technology for recovering copper has improved.

    As the air bubbles rise to the surface of the cells, the hydrophobic copper mineral particles attach preferentially to the bubbles and form a stable froth, which continuously overflows into launders. The process is then repeated twice more to recover almost 90% of the feed copper into only 2% of the feed weight to produce a 32% copper sulphide .
