Underground mines are more expensive and are often used to reach deeper deposits.

AluminumMinerals Education Coalition

Aluminum is the most abundant metal element in the Earth's crust. Bauxite ore is the main source of aluminum and contains the aluminum minerals gibbsite, boehmite, and diaspore. Aluminum is used in the United States in packaging, transportation, and building. Because it is a mixture of minerals, bauxite itself is a rock, not a mineral.

MiningArticle about mining by The Free Dictionary

Although surface and underground mining are the most common techniques, there are a number of other mining methods. In solution mining the valuable mineral is brought into a liquid solution by some chemical or bacteria. The resultant liquid is pumped to the surface, where the mineral or metal is taken out of solution by precipitation precipitation,

Copper Mining and Processing Life Cycle of a MineSuperfund

Surface mining, which includes strip mining, open-pit mining, and mountaintop removal, removes soil and rock from on top of the mineral deposit. It may begin as soon as the pre-development steps are complete. Underground mining uses shafts and tunnels to access deeply-buried mineral deposits, while the overlying rock is left in place.

An Introduction To Surface Mining

However, surface mining can be more environmentally-damaging than subsurface mining. Types of Surface Mining Open-Pit Mining. Known also as "open-cast mining", open-pit mining is the most common type of surface mining. Open-pit mines are enormous holes in the ground; created and increased by blasting and drilling rocks apart.

How Are Emeralds Mined?LEAFtv

Open-Pit Mining. One way to mine emeralds is through the open-pit method. Workers dig a large pit about 12 meters deep and then blast the surface with water to reveal mineral-bearing rocks. In the open-pit mining method, a lot of waste rock must be hauled away. The mining area is literally shaped like a pit that can hold equipment and workers.
