Open Cast Mining Advantages

Feb 24, 2018Examples of disseminated ore deposits are porphyry copper deposits, formed by circulating metal rich fluids in fractured igneous rocks, often resulting in a stock work vein arrangement. These may be tens of millions or billions of tonnes in size, and contain from % to 1% copper and possibly gold at a few parts per million.

Copper Mining and Processing: Processing Copper Ores

Copper mining is usually performed using openpit mining, in which a series of stepped benches are dug deeper and deeper into the earth over time. To remove the ore, boring machinery is used to drill holes into the hard rock, and explosives are inserted into the drill holes to blast and break the rock.

Estimation of Open Cut Mining Recovery and Mining

described as mining loss which is economic mineralisation that has been lost during the mining activity. Mining Dilution is the percentage of material added to the insitu ore during mining. The mineral content of the diluent material is used to recalculate the grade of ore post mining resulting in a diluted grade estimate.
