Open pit mining, also known as open cast or open cut mining, is a surface mining technique of extracting rock or minerals from the earth by their removal from an open air pit, sometimes known as a borrow. This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mining. Open pit mines are used ...
220.127.116.11 Open pit mining. Open pit mining refers to mining directly on the ground surface, thereby producing an open pit. This method is practical and cost effective when the uranium ore is located near the surface . Underground mining and ISL methods may be considered for sites that have uranium ores at deeper depths.

Fig 1 A typical open pit iron ore mine. On the basis of mining methods, iron ore mining can be broadly divided into two categories namely manual mining and mechanized mining. Large iron ore mines are mechanized mines while manual mining methods are employed in the small mines. Manual mining method is normally to float ores.
In open pit mining waste is transported to a disposal site, and the ore is transported to a downstream processing site. This method commonly involves a sequence of benches from the surface to the deposit. As the open pit goes deeper into the ground, all of the benches above are extended outward.
Iron processing, use of a smelting process to turn the ore into a form from which products can be fashioned. Included in this article also is a discussion of the mining of iron and of its preparation for smelting. Iron is a relatively dense metal with a silvery white appearance and distinctive
