Openpit panel mining has been the normal surface method since the early 1960s. A strip or block of bauxite is exposed and mined and then another panel is exposed. The first panel is normally refilled with waste rock. Several panels typically were open at the same time to supply the proper blend of ores to meet mill specifications. Beginning

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
Open pit mining While Sangarédi was the orebody on which CBG’s operations were founded today between 85% and 90% of its output of raw bauxite comes from the Bidikoum and Silidara pits. After stripping any thin overburden the ore is blasted and then loaded using hydraulic excavators into haul trucks for transport to the mine stockpiles.
Bauxite is generally extracted by open cast mining being almost always found near the surface with processes that vary slightly depending on the location. Before mining can commence the land needs to be cleared of timber and vegetation. Alongside this process may be the collection of seeds and/or saplings for inclusion in a seedbank which
Mining and processing at the Cape York Peninsula bauxite mine The project will involve the development of a shallow openpit using the existing fleet of frontend loaders and 180t dump trucks from the East Weipa site.
In open pit operations bauxite is normally extracted from strata typically 46 m thick under overburden that may range up to 10 m thick covered by a thin layer of topsoil with its associated vegetation. At some nonmetallurgical mining sites the overburden thickness may reach 70 m or more.
