Open-pit mining, also known as open-cast or open-cut mining and in larger contexts mega-mining, is a surface mining technique of extracting rock or minerals from the earth 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 when deposits of commercially ...
The open-pit, copper-gold mine began operations in July 1991, and reclamation activities were completed by the end of 1999. As specified in the Reclamation Plan and Mining Permit, the open-pit was backfilled. The backfilling process involved blending the stockpiled waste rock with a prescribed amount of limestone.
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.
All over the world, the limestones are generally mined from a quarry or the open pit mining. It is the easiest way to remove the limestone without causing much destruction. In surface mining or open pit mining, the top soil and the overburden covering the mineral is removed. Then by the process of drilling the rocks or broken. Get Price
