Basics of an open pit mine
Open pit mines can be used in coal mining, and they are used extensively in "hard rock" mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals. In a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining coal. In a hard rock mine, the bottom of the pit would be the ...

OPENCAST PLATINUM MINE PROJECT
· Concor Mining began work on the Impala opencast mining project in 2002 in the vicinity of Impala No. 6 shaft. "We mined the Merenksy ore body first and in 2005 we started mining the UG2 orebody," Rodger Herne, Concor Mining contracts director responsible for this project says. "In a two shift operation, we mine down to the 30 metre level in the pit, while the Impala underground operation ...

Effects of Acid Mine Drainage on Hydrochemical Properties ...
· From mineral exploration to the closing stage, mining methods, both opencast as well as underground, have serious environmental impacts with largescale consequences. Sulphide minerals, mainly pyrite, present in coals when exposed to air and water and get oxidized and hydrolyzed to form sulphuric acid, which further dissolves heavy metals. Formation of AMD is a natural process but it is ...

OpenPit Mining Methods
· 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 ...
