Open-pit mining - Wikipedia
Open-pit, 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 pit or borrow. This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mining.

Starting from either open-pit or underground mining and using a different relevant treatment method for oxide or sulphide copper mineral (ore). Having a quick look now at how porphyry ores are treated and the metals extracted. There are two main process streams; one for sulfide ores and the other for ore that is being weathered to oxidize sulfides the so-called oxide ores. All ore in the pit ...

Basics of an open pit mine - Mine Engineer.Com
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 ...
Open pit copper mining - MAXAM
Open Pit Copper-Mining. Open-pit mining is used when the orebodies are extensive and relatively close to the surface. The sterile/ore ratio is one of the factors which defines the exploitation method and the final dimensions of the mine cuts. In general, open-pit mining consists of a system to exploit open pits with multiple benches. Operations start with drilling and blasting to remove the ...
2. Mining Methods - Copper
In each of these mining methods, various earth-moving equipment including shovels, dozers, hauling trucks, and loaders are used to remove and transport the ore. However, the first step is to loosen the rock in the ore body so that it can be moved and processed. Blasting and grinding equipment are used to accomplish this task. Open pit mining is a technique used to extract copper ore near the ...
Copper Mining and Processing: Processing of …
Copper mining is usually performed using open-pit mining, in which a series of stepped benches are dug deeper and deeper into the earth over time. To remove the ore, boring machinery is used to drill holes into the hard rock, and explosives are inserted into the drill holes to blast and break the rock. The resulting boulders are then ready for hauling; specialized haul trucks, conveyors ...
