I would use 50 per pound as a long term price and suggest that an open pit target that grades pounds/tonne, or approximately % would be an economic intercept over 100 metres. For highgrade, underground deposits, a grade of 1% would be a significant intercept over thicknesses of 2 .
· Recycled asphalt millings cost 12 to 32 per yard or 10 to 20 per ton. Asphalt millings for a 2car driveway costs 60 to 240 without installation. A recycled asphalt driveway costs 2 to 5 per square foot or 1,200 to 3,600 installed. Crushed asphalt prices depend on quality. *Based on a 4inch depth.

This paper will investigate common methodologies of estimating operating costs for mines and present examples from actual operations and why those methods were selected. It will highlight why some methods are superior to others. Finally, we will explore the potential pit falls in cost estimation that often occur and the opportunities that may ...

milling activity loed near the Utec village, the socalled Old San Juan de Lucanas operation. It mined leadzinc ores containing + Ag Oz / ton and Gr Au / ton from 1 m to m wide veins. Operations were shut down in 1983, since then the mine has been inactive and .
The cost of block cave mining is about 1/10 of the correspondent cost of conventional methods. The production rates can reach 30,000 to 100,000 tons per day. Moreover, drilling and blasting costs are far less, and there are no backfilling costs. Another benefit of block caving is the large reduction in surface waste disposal needs.
Estimates of investment requirements and operating costs per ton of feed produced have been developed for 99 model plants. Four groupings form the nu cleus for these model plants, with representative production of 6 to 10 tons per hour, 10 to 25 tons per hour, 25 to 35 tons per hour, and 35 to 50 tons per hour.

Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and reseparate them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the ...
· Generally speaking, one gram per tonne works for openpit mines, but underground gold mines require at least g/t to be economic. Openpit mining is either done with a fleet of haul trucks (some now automated) or an inpit crushing and conveying system (IPCC). Underground mines are accessed via a shaft or ramp.

Mining Costs – CAPEX vs. OPEX. Depending on the loion of the project and the type and quantity of the minerals contained within the deposit, the mining costs can vary a lot between different mining projects. In general, underground mining is more expensive than open pit mining as with open pit mining the minerals are found near the surface ...
An example for a polymetallic deposit can be seen below. Assume a selling price of 2,500, 2,400 and 6,500 per tonne of zinc, lead and copper, respectively. For this example, the selling cost has been chosen to be 5% of the selling price, and metallurgical recoveries are all 90%. A grade of 6, 3 and percent by mass of zinc, lead and ...
