What is Strip Mining (with pictures)Info Bloom

Mary McMahon Strip mining is done layers where the mining operations go slighter deeper with each pass. Strip mining is a type of surface mining which involves the removal of a thin layer of material known as an "overburden" to access buried deposits of useful minerals.This type of mining is only effective in areas where mineral deposits are very close to the surface making it feasible to

Uranium How is it Mined

Open Pit Mining. Open pit mining also known as strip mining is the removal of surficial soils and uneconomic rock to get at the ore below. Ore grades are normally less than 0.5 . This is type of mining is only possible if the uranium ore is near the surface (normally less than 400 ft).

Environmental Risks of Mining

 · Open pit mining where material is excavated from an open pit is one of the most common forms of mining for strategic minerals. This type of mining is particularly damaging to the environment because strategic minerals are often only available in small concentrations which increases the amount of ore needed to be mined.
