Openpit operations ore of a particular mine and is represented in grams per metric ton factor weighing on mining costs is that gold production is becoming more and more reliant on
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
#0183;#32;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.
#0183;#32;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
The conveying and processing system consists of an HLT (Heavy Load Truck) tipping station at the bottom of the pit wall, two skips running in opposite directions on a ropeway system, each with an average payload of 136 tons of ore or overburden, and a track system for the two skips (See Figure 2).
As a rule of thumb, open pit mining can process ore for 10 per tonne and, where the ore grade is more than double that at 20 per tonne, results would be economic. Consider that 1% of a metric
Openpit mining, also known as opencast or open cut mining, is a surface mining technique of extracting rock or minerals from the earth by their removal from an openair pit, sometimes known as a borrow.. This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mines are used when deposits of commercially useful ore or rocks

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:
For 1999 and beyond, mining cost per ton is expected to be in the range of to The depth of the pit and the height of the heap leach pad impact the truckhaul cycle time and unit cost, which is the most significant component of mining costs. Processing Rates The crushing/processing rate is
Open Pit Mine Design, Mining Geotechnics. Geotechnics for Mining Infrastructure 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 exist to lower mine costs.
Scale, grades, processing costs, open pit vs underground. The interesting aspect of the AISC metric is the number of factors that feed into the final figure, and similar to any other sector costs, they can vary from month to month and year to year. In the case of gold stocks, better grades usually translate into lower cost mines.

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 200400 meters depth in bulk tonnage.. The mining costs are estimated in a mining companys feasibility study which, when available, can be found on the companys website (often hidden between the news releases).

Open Pit Mining Costs Per Ton For 1999 and beyond, mining cost per ton is expected to be in the range of to The depth of the pit and the height of the heap leach pad impact the truckhaul cycle time and unit cost, which is the most significant component of mining costs. Processing Rates The crushing/processing rate is 21,500 tpd.
