I estimated that the delivery, pick-up, and insurance would cost $300 each time I rented. I would also have to buy the fuel for which I used my earlier estimate of $3.25 per hour. My total estimated hourly costs for renting an excavator thus came to ($1000 + $300) / 25 hours + $3.25 per hour = $55.25 per hour.

The paper shows that energy costs typically comprise one of the largest on-going costs of mining operations, of which 70% is devoted to the comminution of the ore. Furthermore, the most significant energy cost occurs in the grinding circuit, where up …

Even though drill and blast costs in the ore have increased, the overall net benefit to Mt Rawdon, including mining and processing costs, is expected to be more than $5 million. While the Vistis system is a key input to the mine to mill program the benefits Mt Rawdon achieved are equally attributable to the operational changes it made.

Expressed in another way, the sorting cost per ton of run-of-mine ore is 1.95/6.51 or $0.30. The cost of mining 1 ton of run-of-mine. ore is $2.34. The cost of transporting ore from the mine to the mill on contract is $1 per ton. 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.
