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

Fine Gold Recovery System Gravity Separation Table

If the ore product contains a combination of coarse and fine free gold, the modular Gravity Flotation Intensive Leach (GFIL) system can produce a higher yield product. For ores smaller than 50 micron, the particle weight is too light for physical separation by gravity; therefore gold recovery will require a modular chemical flotation process.
