The purpose of this data-file is to tabulate typical cost estimates for crushing-grinding processes, which consume 1-2% of all the energy in the world and 20-50% of the energy in some mining processes. Our numbers are shown per ton of ore, so clearly lower ore grades translate into higher costs per unit of extracted material ().Energy economics.
The milling cost of run-of-mine ore is taken as $2.85 and the cost of milling the sorted product is $3.22 per ton. The mill recovery on the unsorted ore is estimated at 80 percent, and the recovery on the sorted ore is 87 percent. The profit per ton of ore without sorting is shown in the following calculation:
The first step in mill design is the flowsheet based on reliable ore tests. The mill capacity and equipment sizes as shown has been selected as an example for treating 500-550 short tons of ore per 24 hours per day. Two-stage grinding is to all minus 65 mesh for an average ore.

Hard ore Work Index 16 = 100,000/65,000 = 1.54 kwh/t. 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 ...
