Finding the Ore Liberation Size For Gravity Circuits

Tune the grinding circuit to only grind fine enough to attain the commercially-viable liberation size. If gold is found in the 200-300 or <325 mesh fractions, it is likely gold-bearing sulfides or free milling gold <~400 mesh. This gold is not practical to recover via gravity concentration, so flotation or leaching could be used. Additional notes
