Jun 22, 2018· This stage of themining processrequiresestablishing a path to the mineral deposit. That path, however, requires more than excavation. In order to even begin work, mining rights must be acquired, access roads must be constructed to help workers navigate the …
The nature of the ore deposit determines the mining andmineral processingtechniques applied.Oxide oredeposits are frequently of such low grade ( e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then piled into heaps for extraction by cyanidation (see below).

Special bacteriaare sometimes used as part of this process. After recovery, the metals may be still further refined (purified) or alloyed with other metals, as in a copper refinery or steel mill. Mining, processing, and refining are thus successive steps in the utilization of an ore deposit to yield a metal. William Andrew Hustrulid

Massive deposits at great depth make good targets from underground miningbecause thegrade of the oreis high, so every tonne of ore mined underground brought to the surface has great value, they are often so deep, it is not economical to uncover them in an open pit and once they are accessed by a tunnel, they can be progressively extracted in a productive manner without having to mine through …
