method identify drilling mining iron ore
Ore Body Model: Iron Ore Example
the ore response in the process may also be impacted by extraction sequence, processing available, operators' team working at the plant, and batch with which the extracted block was blended during the process. However, those factors would have a lower impact on the process performance in iron ore mining than in, for example, copper or gold ores.
Mining Underground mining |
Mining Mining Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on the ...
Calculation of Ore Tonnage Grade from Drill hole Samples
The standard method of making these estimates is to find the cubic contents of triangular prisms, in the apexes of which the drill holes are placed, by multiplying the surface area by the average depth of the ore in the three drill holes and then multiplying the cubic contents by the specific gravity of the ore or rock to find the tonnage.
