    This may be ‘entrapped in sulfides'. A standard ball mill may grind your ore to 75 microns. Fine grinding is one process available to liberate refractory gold. Gravity Recoverable Gold (GRG) refers to how much gold you can recover based on how fine you are grinding/milling your ore. The GRG (Gravity Recovery Gold) testing is available at Met-Solve Labs. The number 1 application for iCON

  • Common & Basic Formulas for Mineral Processing

    A mechanical classifier often receives its feed from a ball mill and produces (1) finished material which overflows to the next operation and (2) sand which returns to the mill for further size-reduction. The term “circulating load” is defined as the tonnage of sand that returns to the ball mill, and the “circulating load ratio” is the ratio of circulating load to the tonnage of
