Extraction of Mineral Resources

extraction of solid, liquid, and gaseous mineral products from the earth’s interior. The process of extracting mineral resources involves digging them out and transporting them from the faces to the surface outside the mining excavation. Solid mineral products are extracted by the open-pit and underground methods. Peat is extracted from the surface with full mechanization of the basic production processes. The extraction of liquid mineral products and natural gas by wells drilled from the surface is being done on an ever-increasing scale. In the 1960’s extraction was begun of solid mineral products, such as gold, tin, diamonds, zircons, monazite, and ilmenite, as well as petroleum, from the sea floor.
