Mineral Extraction - an overview | ScienceDirect Topics

Mineral extraction sites, which include strip mines, quarries, and underground mines, contribute to surface water and groundwater pollution, erosion, and sedimentation (see Chapter 14). The mining process involves the excavation of large amounts of waste rock in order to remove the desired mineral ore (Fig. 12.6). The ore is then crushed into ...

Extraction of Metals: Methods, Processes Involved ...

Extraction of metals from their compounds is also a reduction process. Besides using carbon (coke) to reduce metal oxides to metals, sometimes displacement reactions can also be used. The highly reactive metals such as sodium, calcium, aluminum, etc. are used as reducing agents because they can displace metals of lower reactivity from their ...

MINERAL EXTRACTION OPERATIONS

Mineral extraction operations locate where mineral deposits exist. The location of such mineral resources is dependent on nature (specifically geology) versus land use or zoning districts. Mineral deposits having potential for extraction are usually located in land zoned agricultural (A1-EX, A-1, and A-2).
