Open pit mining method is one of the surface mining methods that has a traditional cone-shaped excavation and is usually employed to exploit a near-surface, nonselective and low-grade zones deposits. It often results in high productivity and requires large capital investments, low operating costs, and good safety conditions. The main topics that will be discussed in this chapter will include ...

Copper mining. The following gives an overview of how copper is extracted from its ore and converted into pure metal. Mining. The ore is removed from the ground in either open pit or underground mines. Underground – sinking a vertical shaft into the earth to reach the copper ore and driving horizontal tunnels into the ore.
Morenci Copper Mine, Arizona. The Detroit Copper Company started mining at Morenci, 16km south of Silver City, Arizona, in 1872. A P&H 2800 mining shovel loading a 973 hauler. Hauling waste rock to backfill the worked-out pit requires a big truck fleet. One of Morenci's 797,272t (300st) capacity mechanical-drive haul trucks.
4.2 Open-pit mining. Open-pit mining is probably most advanced because of developments in mining low-grade copper deposits and iron ore. It is suitable for much of the resource if it is done on a large scale and will allow low-cost removal of most of the resource.
Hence, an attempt has been made to predict the flyrock of Soungun Copper Mine, Iran taking into account the hole length, spacing, burden, stemming, powder factor and specific drilling by support vector machine. To find the suitability and applicability of SVM, predicted results were also compared by multi-variate regression analysis results. 2.
Located near Gällivare, northern Sweden, the low-grade Aitik copper deposit was discovered in the early 1930s. Bulk-mining technology made exploitation feasible in the 1960s and mining at Europe's first large, low-grade open pit copper mine started in 1968 at a production rate of 2Mt/y of ore.Since then, a series of pushbacks have increased output to approximately 19Mt/y.
Codelco has other operations in the area, Chuquicamata and Radomiro Tomic, mining primarily high volumes of low-grade copper. Members of the head office put together a pilot project to mine 52 m banks (Talud-Vertical). The strategy reduced the amount of overburden to be excavated and allowed workers to go down to greater depths in the open pit.
Large open-pit copper mines can produce up to a million tons of waste and ore per day and can be mined at that rate for decades. Quarrying is similar to open-pit mining except the term is commonly applied to the extraction of dimension stone and aggregates.

Open-pit mining, or open-cast mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow.. This form of mining differs from extractive methods that require tunneling into the earth, such as long wall mining. Open-pit mines are used when deposits of commercially useful minerals or rocks are found near the surface; that is ...
Curipamba open pit polymetallic mine to yield NPV of $259 million. The Curipamba open pit polymetallic mine in Ecuador will yield a net present value (NPV) of US$259 million at an 8% discount rate, a Prefeasibility Study from Advantus Mining and Salazar Resources has found. The mine will produce gold, silver, lead, copper, and zinc.
The deepest mine. Bingham Canyon Mine, located near Salt Lake City, is the world's deepest man-made open pit excavation. The mine is 2.75 miles (4,5km) across and 0.75 mile (1,2km) deep.
