    Free-milling gold ores are defined as an ore from which standard cyanidation (which takes about 20-30 hours) can extract more than 90 of the gold under the condition that the ore size is 80 < 75 µm (Joe Zhou 2004). Complex ores meanwhile require significantly higher cyanide or oxygen levels to attain an economic recovery (Brooy 1994).

  • Particle Size Analysis for Mining and Minerals

    In many cases the valuable minerals are mixed with gangue commercially useless material and the ore must be separated. The first step of many separation processes is comminution (size reduction) followed by classification (separation by particle size) either for further grinding or the next step concentration of the ore.
