In a 10 year period, the gigantic Consolidated ia Mill processed over 800,000 tons of gold and silver ore worth around sixty million dollars. This description of the amalgamation process is very simplified as I have failed to mention many other steps and equipment (see the epilogue for a first person account of a milling setup).
In processing our local ore with the MBMM jaw crusher, hammer mill and shaker table, we get a p80 of ~30-50 mesh (80% passing 30 or 50 mesh sieve screen), depending upon the slot size in the hammer mill screen. Results show nearly 50% of the gold recovered was at <100 mesh, and a surprising amount of gold was at <325 mesh.
In one case known to the writer the product obtained from a bucking table, putting everything through a 100-mesh sieve, only contained 50% of — 200 material whereas the finished mill pulp on the same ore contained 5% of + 100- …

Ball Mill Crushing by tube-mills were first introduced into the crushing departments of cyanide plants when it was found that for crushing finer than 30-mesh other types of crushing machinery were not efficient. In order to crush with one pass, these mills were made 18 to 22 ft. (5.5 to 6.7 m.) in length. Pebbles were used as a grinding …

With the mix of rods, and the mill running over night, we got a dry grind of < 200 mesh on about 20 Kgs. of minus ¼" ore. That's a 86 times reduction. Remember, …
Weight and transfer ore to the ball mill. Grind dry for 100 revolutions. Empty the ball charge and ore through a coarse screen to separate the balls from the ore. After mill and balls are swept clean, screen and ground ore through the mesh screen to be tested, using coarser protective screens if necessary.
For the purposes of this example, we will hypothesize that the the crushing index of the hard ore with the increased energy input of 1.54 kw/t reduces the ball mill feed size to 6,500 micrometers. As a result, the mill output will increase with this reduced size to approximately 77,000 tons per day.
