Low cost per ton may involve loss of ore or excessive dilution with waste and a low-cost-per-ton method may not, therefore, be the most economical one in a given instance. Table 38, giving stoping costs per ton of ore mined, should be considered with the foregoing important fact in mind.
During mining, "it is assumed that other veins will be encountered . . .that will add to the tonnage." Approximately 80,000 tons of open pit ore is also available on the top of the Tunnel outcrop and in the vicinity of the No. 3 Adit. At an average of 0.50 oz. gold per ton…
capacity, gold price and dilution rate vary. Open-pit mining operations are long-term investments, and therefore, are subject to possible unexpected changes during the mine exploitation stage. This analysis is performed in order to appreciate the possible economic

For 1999 and beyond, mining cost per ton is expected to be in the range of $0.85 to $0.90. The depth of the pit and the height of the heap leach pad impact the truck-haul cycle time and unit cost, which is the most significant component of mining costs. Processing - Rates The crushing/processing rate is 21,500 tpd. It is expected to rise to ...
Electrical costs are a small cost component for the open pit mine models and are included in the construction material category. Note that capital costs are expressed in dollars and operating costs in dollars per short ton of material (ore and waste) mined.
The variable portion of the cost calculation is based on the open pit mining models published by the USGS, which take into account several factors that affect capital expenditures (Camm, 1991). From these, the following calculations were made: The average operating cost per ton ore produced was also calculated using D:
In general, underground mining is more expensive than open pit mining as with open pit mining the minerals are found near the surface at a maximum of approximately 200-400 meters depth in bulk tonnage.. The mining costs are estimated in a mining company's feasibility study which, when available, can be found on the company's website (often hidden between the news releases).
Jul 21, 2015· Yet there's another negative factor playing against Wyoming coal that doesn't get as much attention as regulatory matters — the rising cost of mining in the Powder River Basin. Using open-pit strip mining methods to scoop 50 to 70 feet thick coal seams, the Powder River Basin has long been one of the lowest cost coal-producing regions in ...
The local copper smelters use the silica as a flux in the production of copper, extract the silver and gold values and remit 85% to Dane Mining & Exploration. Mining costs for Dane are estimated to be $15.00 per ton. Transportation costs to the smelter, $10.00 per ton. This will make the cost of mining and shipping $25.00 per ton.

This article presents cost models for open pit mines, which takes into account cost uncertainty. In this paper, cost uncertainty is considered as cost of under production, and cost of over production.
Mining Cost Model. 5,000 Tonne per Day Open Pit Mine Model. This mine is an open pit mine producing 5,000 tonnes ore and 5,000 tonnes waste per day. The total resource to be mined is 18,715,000 tonnes. Ore is hauled 1,068 meters to an ore stockpile. Waste is hauled 535 meters to a waste rock dump.
Assume the open pit mining the costs are $2.75/ton of ore (OP) and a stripping cost of $1.85/ton of waste (SC). SR = (UG - OP)/SC SR = (12.00 –2.75)/1.85 = 5.0 tons of waste/ ton of ore i.e. while the stripping ratio is less than 5.0 it is most profitable to mine the deposit by open pit. When the stripping ratio exceeds 5.0 it will be more profitable to mine the deposit using the underground ...
Processing capacity at the open pit, located 25km from the Moscow-based company's flagship Olimpiada mine, is 6m tonnes of ore per year, which makes it the largest facility of its kind in Russia.
Open Pit Gold Mine: The CEO's concern with his open-pit gold mining operation in Peru was the decline in metal prices and an increase in cost per ton. Additionally, as the productive life of the mine was coming to an end, establishing an organizational structure that was in line with the current reality to maintain a cost-effective operation ...
Two main types of mines Open pit mining Roughly ten times lower in cost per ton compared to under ground mining Slope stability decide waste/ore ratio With low grades a high production rate is needed Big equipment for high volume production Under ground mining Under ground mines commonly have lower production rate Increased cost to infrastructure and ground support
12 Underground vs. Open Pit Conversion from Open Pit to Underground at BHP Billiton's Koala diamond operations, Canada's Northwest Territories. (E&MJ, 2006/08) Underground vs. Open Pit Compare total mining cost per ton of ore for each method. Surface costs are dependent on stripping ratios.
In mining, stripping ratio or strip ratio refers to the ratio of the volume of overburden (or waste material) required to be handled in order to extract some tonnage of ore. For example, a 3:1 stripping ratio means that mining one tonne of ore will require mining three tonnes of waste rock.
