Operating costs are based on daily capacity (st/d) and are expressed in dollars per short ton ($/st). The open pit models are based on X = st/d of ore and waste moved. This allows for the wide variability in stripping ratios found among different open pit operations.
Open pit scheduling programs such as Whittle 4D propose pit outlines and preferred areas of mining based on grade and mining cost-per-ton. At Sandsloot open pit a single mining cost-per-ton was derived for the entire pit. Mining cost-per-ton, however, varies per zone and therefore should be generated for each geotechnical zone.

An example of mine life, capacity, and underground equations is in appendix D. Assume a SR of 2:1, 10,000 st/d ore, 20,000 st/d waste, for a total of 30.000 st/d of material mined per day, 260 d/yr. Milling is 350 d/yr, so the feed rate to the mill is 10,000 (260/350) = 7 429 st/d. LARGE OPEN PIT MINE. For a production rate of 30,000 st/d ...
the cost per ton would be much lower. Examples are the open-pit Texas uranium deposits, where shipping-mill heads costs are about $25/lb for -04% U 0 ore.

Downloadable (with restrictions)! In the process of planning an open-pit, the determination of optimum cut-off grade plays a vital role. The classical approach of Lane's algorithm yields infinitely many solutions when the metal price is very high and mining, milling and refining costs are low. This problem has been addressed through a new algorithm.
Open pit mining costs range from $1.50 to $4.00 per ton of material depending on whether the mine is operated by the owner or by a contract miner. Costs per ton of ore will depend on the waste to ore ratio. Oxide ore processing ranges from $5.00 to $10.00 per ton. Refractory ore processing could be as much as $30.00 per ton.

Cost-efficient Transport for Open-pit Mines. An innovative technological approach to skip haulage could optimize costs and energy efficiency in hard rock mines. Open-pit metal mines are often shaped like an inverted cone, with the ore and overburden being drilled and blasted, then loaded and transported by shovel-and-truck systems.
Optimum cut-off grade policy for open pit mining operations through net present value algorithm considering metal price and cost escalation. By Raul Cezar. Maximizing the net present value by applying an optimal cut-off grade for long-term planning of the copper open pits.
