Copper grade is the concentration of copper in the ore rock. To calculate the grade of copper for the sample, geologists use the equation: (amount of copper metal/amount of copper ore rock)*100 2. If a deposit area has 200lbs of copper in 10,000lbs of ore rock, what is the grade? 200/10000*100=2% 3.

Long-wall Mining. Long-wall mining is a method in which a 'long', horizontal 'wall' of ore is excavated from one of its faces. This wall is usually several miles long and hundreds of meters wide. Excavation usually begins from the ore face opposite the entryway, and artificial support is provided to the excavated space (stope).

Concentration of the Ore When an ore has a low percentage of the desired metal, a method of physical concentration must be used before the extraction process begins. In one such method, the ore is crushed and placed in a machine where, by shaking, the heavier particles containing the metal are separated from the lighter rock particles by gravity.

Stop limiting the amount of gold you could be recovering and speed it up! Gravity concentrators produce gold from ore in a matter of minutes or hours rather than days or weeks. By introducing concentrators into your circuit, you can experience faster recovery times, allowing you to produce gold more quickly, which in turn improves your cash flow.

An "ore deposit" is a mineral deposit which has high enough grades of metal that makes it economic to mine. Essentially this means that per tonne of rock containing the desired minerals, the costs of removing the minerals from the rock and separating the metal from the minerals are lower than the value of metal per tonne of rock.

An ore is a rock in which a valube or useful metal occurs. The more demand a certain rock has the more value it has thus it will be more valuble to be mined. The higher the concentration factor, the richer the ore, and the less of it needs to be mined to extract a given amount of the metal. In General, the minimum concentration factor required ...

The geological grade of the ore deposit is relatively high (about 50%), but the ore body is thinner or has more interlayers. The waste rock is mixed in during mining to dilute the ore. For this kind of ore, only crushing and no-grinding can be used so coarse-grained tailings are discarded through re-election to recover the geological grade.
