Open pit bauxite mining operations may use backhoes, bucket wheel excavators, bulldozers, draglines, power shovels and scrapers for the stripping of overburden from the ore. In addition, draglines, frontend loaders, and power shovels are commonly used to excavate and load the crude ore.
mining: Openpit mining Deposits mined by openpit techniques are generally divided into horizontal layers called benches. The thickness (that is, the height) of the benches depends on the type of deposit, the mineral being mined, and the equipment being used for large mines it
Openpit mining methods are applicable to mining ore deposits that apex at or near the surface. If the deposit apexes below the surface, the overburden and barren capping overlying the ore must be removed in advance of openpit mining. The removal of this material is known as stripping. The strippingpit limits must be extended beyond the limits of the ore pit to provide a bench, and the pit

Bauxite is generally extracted by open cast mining, being almost always found near the surface, with processes that vary slightly depending on the loion. Before mining can commence the land needs to be cleared of timber and vegetation.
Open pit 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.
Jan 18, 2012 Bauxite is usually mined by open cast or strip mining. Rather than tunnelling into the earth these methods involves extracting minerals from an open pit. All the earth covering the minerals is removed by heavy machinery. The mining of bauxite in the study area is done: (a) From the surface (opencast mines), Bauxite Mining
