  • gravity impact gold ore

    The Impact of Gravity Gold Recovery at KalgoorlieThe gravity circuits were commissioned in August 2004 and have since consistently recovered 10 to 20 per cent of the gold present in the KCGM ore delivering a reduction in coarse gold losses equivalent to 0.45 per cent additional metal recovery and contributing to improved metal accountability.

  • NC DEQ: Gold of NC

    Pyrite and yellow-colored mica are frequently mistaken for gold but can easily be distinguished. Gold is very soft (2.5-3 on Mohs scale of hardness) and can be hammered into thin sheets without shattering. It is heavy (specific gravity of 19.3 when pure) and is insoluble in all acids except aqua regia (a mixture of hydrochloric and nitric acids).
