The value created per ton of broken ore is the difference between the price it commands when sold as the final product and the cost to produce it. Traditionally, the total process in the mining industry is classified into two groups as mining and milling. These are managed as separate cost centres inspite of the interdependency.

The gross ton-nage basis for costs is particularly important in the copper industry, because ore grades are very ‘Simon D. Strauss,Trouble in the Third Kingdom (London: Min- ing Journal Books, 1986). low (often0.5 to 2.0 percent Cu). At these low levels, small differences in ore grade represent large variations in the tonnages of ore that are handled for each tonne of copper recovered, and

(PDF) Stripping Ratios, Pit Limits & Cutoff Grade

For open pit mining the costs are $0.40/ton ore and a stripping cost of $0.50/ton of waste. SR = (3.00 -0.40)/0.50 = 5.2 tons of waste/ ton of ore i.e. while the stripping ratio is less than 5.2 it is most economical to mine the deposit by open pit. With mining of bench 8, another 5,000 ft 2 of ore (A 6) is removed.

Ore Wikipedia

Ore is natural rock or sediment that contains one or more valuable minerals, typically containing metals, that can be mined, treated and sold at a profit. Ore is extracted from the earth through mining and treated or refined, often via smelting, to extract the valuable metals or minerals. The grade of ore refers to the concentration of the desired material it contains.

The tertiary product is stored in a 20,000 t fine ore bin ahead of the ball milling circuit. Fine ore is reclaimed from the bin via eight reclaim belt feeders (two per four parallel milling trains) and delivered to the fine screens ahead of ball milling. Each line consists of two screening units. Undersize material from the screens reports to one of four cyclone feed hoppers and the oversize
