Finding the Ore Liberation Size For Gravity Circuits ...

–Percentage recovery of total gold is computing by taking total gold recovered in ports 1 and 2 (free milling, >~400 mesh), divided by total gold in ports 1, 2, 3, and 4 (includes very fine free gold and gold-bearing sulfides from assayer). A hammer mill or impactor produces a fairly coarse grind. Usually, about 30-50 mesh is the practical limit.
