Opening New Mines

The capital cost of mining was calculated using the equations below, where D is the daily capacity of the mine in tons of ore produced per day. The constant (i.e., first) term in each calculation is a blanket estimate based on published average initial capital investment in the industry (~USD 500 million for what is defined in this analysis as a large capacity mine) (Schuler, 2011).

 · K = F /C = (c — t)/ (f-t) = the concentration ratio. At operating plants, it is usually simpler to report the K based on assays. If more than one mineral or metal is recovered in a bulk concentrate, each will have its own K with the one regarded as most important being reported as the plant criteria.

Productivity in mining operations: Reversing the downward trend …

 · Given that mining companies typically measure the output of the actual ore being mined, rather than the total material moved, productivity measured in this way tends to be constantly in decline. Another important factor concerns more extensive regulatory requirements across the industry worldwide; these can directly or indirectly affect productivity but, again, lie largely outside management ...

Cost of Producing Concentrates from Ore

 · Many companies are engaged only in mining or in mining and milling, and their final product is then either ore or concentrates; hence, cost per ton is the natural and convenient basis to employ. However, the value of ore or concentrate depends on the salable metal it contains, and the measure of profit or loss is the cost per unit of metal in relation to the price at which it can be sold.

Environmental Risks of Mining

Environmental hazards are present during every step of the open-pit mining process. Hardrock mining exposes rock that has lain unexposed for geological eras. When crushed, these rocks expose radioactive elements, asbestos-like minerals, and metallic dust. During separation, residual rock slurries, which are mixtures of pulverized rock and ...

Accounting for Mining (#261) — AccountingTools

 · Under this approach, you estimate the total output expected from the mine, and then amortize the proportion of the total output actually mined. So, if the capitalized amount of development costs is $1 million, and the mine has just produced 2% of the total amount of expected ore, then you can charge 2% of that $1 million to expense in the current reporting period.

Dilution and ore recovery

Dilution is the waste material not separated from the ore in the stages of mining, and is sent to the processing plant. It is defined at the ratio of tonnage waste mined and sent for processing over the combined ore and waste tonnage milled. The following equation is the expression used for dilution:
