Pit mining. Sometimes valuable geologic resources appear at the surface of the Earth but extend deeper into the Earth — sort of a tipoftheiceberg kind of thing. In this situation, pit mining (also called openpit mining) is an option. Pit mining involves digging a large hole to .
This flowchart made of machinery icons explains or expresses in simple but clear terms the step of the Copper Mining and Copper Extraction Process. Starting from either openpit 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.
The most predominant surface mining methods used for mining of iron ores are open pit mining methods and open cut mining methods. However a few underground iron ore mines are also in operation around the globe. The decision for employing surface mining or underground mining is dependent on the proximity of the ore body to the surface.

I needed info on how are diamonds extracted from kimberlite and the open pit mining process was really useful. What''s ur last name? i''m doing a project and i''m trying to cite u.
The ore body is too deep to mine profitably by open pit. The grades or quality of the orebody are high enough to cover costs. Underground mining has a lower ground footprint than open pit mining. The underground mining methods we use include room and pillar, narrow vein stoping and largescale mechanised mining.

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.

The mine has worked surface and underground mineralisation along an 8km northsouth strike length but mining is now mainly underground, extending to depths of 1,600m. The mainly flatback, cutandfill stopes used to exploit several ore blocks are being converted to mechanised open stopes.
Sep 19, 2011· Cost Reduction in Mining Operations Discussion The operating cost structures of mining operations globally have increased significantly over past years. When raw material prices are high it might appear to be an odd time to be thinking about cost reduction, but in fact it is the ideal time. History has shown us is that.
Oct 02, 2015· This is a very basic idea of how the Open Pit Mining process takes place. This was a very new mine when the footage was shot, and using very small machines.
· The stripping ratio describes the unit of overburden that must be removed for each unit of crude ore mined. A typical open pit iron ore mine is shown in Fig 1. 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.
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.

Openpit Mining Openpit mining, also known as opencast mining, opencut mining, and strip mining, means a process of digging out rock or minerals from the earth by their elimination from an open pit or borrow. The word is used to distinguish this type of mining from .
Openpit mining or opencast mining refers to a method of extracting rock or minerals from the earth by their removal from an open pit or borrow. It is a form of surface mining. The term is used to differentiate this form of mining from extractive methods that require tunneling into the earth, like longwall mining.
The first open pit mine in Zone 2, had a stripping ratio of 4:1 and benches in waste are 10m high while those in the ore are 5m high. Underground mining uses a singlepass mechanised cutandfill method in 8–10mwide by 5mhigh panels. Backfill is supplied from the open pits and underground development. As the permafrost extends below the ...
