How do we extract minerals? - USGS

Placer mining is used to recover valuable minerals from sediments in present-day river channels, beach sands, or ancient stream deposits. More than half of the world’s titanium comes from placer mining of beach dunes and sands. In placer operations, the mined material is washed and sluiced to concentrate the heavier minerals.

Extraction of Mineral Resources Article about Extraction ...

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.

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 finely ground tailings for chemical processing and separation to extract the target minerals. After the minerals are processed,

Consequences of over Exploitation of Mineral Resources

Most of our mineral deposits occur as a complex mixture of a number of mineral elements. After removal of top soil and rocks we dig out the desired mineral leaving behind others which are often left in the open as waste materials. Extraction of one element usually scatters and wastes a number of other elements, many of which are in short supply.
