How to profit from low-grade gold mines - Part 1 - Mining News

20/06/2019  Generally speaking, one gram per tonne works for open-pit mines, but underground gold mines require at least 2.5 g/t to be economic. Open-pit mining is either done with a fleet of haul trucks (some now automated) or an in-pit crushing and conveying system (IPCC). Underground mines are accessed via a shaft or ramp. Miners extract the ore through ...

Abstract - USGS

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. All costs are based on daily capacity of the mine (X) in short tons per day of material (ore and waste) moved. Figure 2 summarizes the ...

Operating Cost for Miners SRK Consulting

Mine cost estimation may be done at many levels. At first it may be a simple “back of the envelope” estimation using similar operations to benchmark against. Later it may be decided to use an existing mine that the company owns and factor and compare costs against them. In the final stages a detailed bottom-up estimation based on first principles may be completed.
