As a result, in many instances gold-mine development has been the advance guard of civilization in regions where other mineral resources were
  • Double-Refractory Carbonaceous Sulfidic Gold Ores

    2016-1-1 · Ultra-fine grinding (P 80 ≤ 10 μm) has been proposed as an alternative to “unlock” gold from sulfidic refractory ores; however, the cost of size reduction to this level makes it applicable only for concentrates (Corrans and Angove, 1991, Gonzalez-Anaya et al., 2011), as is practiced at Kalgoorlie Consolidated Gold Mines, a joint venture

    These methods often do not provide high gold recoveries, particularly with respect to fine gold particles. For centuries, gravity methods were gold miners’ preferred separation method as there is a large difference between the specific gravity (sg) of gold (sg ≈ 19.3) and common silicate gangue minerals (sg ≈ 2.7) such as quartz sand.

  • The Chinese Iron Ore Deposits and Ore Production

    2018-7-11 · Probably due to large national land area and multi-period orogeny, from the view of metallogeny, lots of iron deposits developed in China, and the proven total reserves of iron ores are relatively abundant, but mainly low-grade ores. For years, China’s iron ore reserves are far from being able to meet the requirement of rapid development of steel industry.
