Mining Outlined Mind Map
Mining is the extraction of valuable minerals or other
geological materials from the earth, usually from an ore body, vein or (coal)
seam. Materials recovered by mining include base metals, precious metals, iron,
uranium, coal, diamonds, limestone, oil shale, rock salt and potash. Any
material that cannot be grown through agricultural processes, or created
artificially in a laboratory or factory, is usually mined. Mining in a wider
sense comprises extraction of any non-renewable resource.
