In the extraction of minerals, the main aim for large scale mining companies is to excavate large quantities of waste rock from ore deposits, and to refine and purify targeted minerals through mineral processing.
At mineral extraction sites, such as strip mines, quarries and underground mines, mineralisation (and associated waste rock) from the Earth’s crust is recuperated for profit.
Extraction sites rich in mineral resources (rich mineral/ore deposits) are profitable for mining and processing projects as resource extraction can be faster.
There are many mining and processing methods employed to extract minerals from ore, yet, when focusing on the mining aspect, there are 4 main types of mining (as indicated below).
Mining methods can be divided into two general excavation types: open pit mining (surface mining methods) and underground mining (sub-surface).
Mining types are also dependent on the valuable mineral resources being mined. For example, coal mining differs from the method used for valuable metals found in metal ores (e.g., iron ore).
Additionally, mining types are dependent on the mineral deposit itself, and whether it consists of soft or hard rock.
