Crushed ore in the leach pad. The pregnant leach pond is in the distance. The crushed ore rests on a leak-proof membrane to protect the underlying ground and prevent the acid and copper ions polluting the local water table. 2. Dilute sulfuric acid is poured over the crushed ore using an irrigation system. (Courtesy of Red Tiger Mining Inc.)

Mining - Underground mining | Britannica

Strip mining is the process of mining a seam of mineral by removing a long strip of overlying soil and rock. Strip mining is a practical type of mining when the ore body that is to be extracted is near the surface. Open-pit mining is the process of extracting rock or minerals from the earth through their removal from an open pit or borrow.

Depressurization as a Strategy for Mining Ore Bodies with ...

Mining - Mining - Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on the ...

Mining Methods: Block Caving | Geology for Investors

Ore is an economic concept, defined as a concentration of minerals, which can be economically exploited and turned into a saleable product. Before a mineral deposit can be labelled as an ore body, full knowledge is required about the mineralization, proposed mining technology and processing methods.

Underground Mining Methods – EXCELLENCE IN MINING ...

Open-pit 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 open-pit mining. The removal of this material is known as stripping. The stripping-pit limits must be extended beyond the limits of the ore pit to provide a bench, and the pit ...

Sep 11, 2020· Block (gravity) caving is a bulk underground mining method, which allows large low-grade deposits to be mined underground. This method involves undermining the orebody to make it collapse under its own weight into a series of chambers from which the ore extracted.

Jul 01, 2019· On sill levels consolidated rock fill (CRF) is placed to separate mining blocks. At Dvoinoye, the same method as Kupol is used for ore thickness less than 20 m while the transverse open stoping method is adopted for thicker zones (>30 m). An ore zone between 20 and 30 m may be mined using either method depending on its scale or extent.

Digging deeper: Mining methods explained | Anglo American

Mar 14, 2014· Mining techniques usually consist of two types based on excavation methods. These are surface mining and underground mining (sub surface mining). Iron ore is almost exclusively mined by surface operations. The most predominant surface mining methods used for mining of iron ores are open pit mining methods and open cut mining methods.

Mar 29, 2014· Caving Method:- It comprise of following techniques:- A. Top Slicing:- The method is used where wide veins or massive ore bodies are worked, when clean ore and high% of recovery is required. It is used when both roof and ground surface need not required any support. The ore is mined in horizontal surface,comprising S1, S2 S3 S4 .

Major Mines & Projects - Mining Intelligence and News

There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.

Copper Mining and Production Processes Explained

Oct 17, 2019· There is a variety of mining methods used, often in the same mine, depending on the geometry of the orebody and the stability of the rock. Ore is broken up by blasting and drilling. Ore is then removed or "mucked out" by a LHD (load haul dump) machine, which resembles a low-profile articulated front-end loader.

Mining of Iron Ores – IspatGuru

Mining is advancing into the Kapit area where temperatures of up to 200°C and fluid pressures of up to 15 bars are expected. The strategy considered for this area is to depressurize the ore body to induce seawater encroachment to cool down the ore body. The challenge in this area is to achieve depressurization and cooling of the ore body without

Mining Methods: Block Caving | Geology for Investors

Jul 21, 2016· Block caving is a large-scale or bulk mining method that is highly productive, low in cost, and used primarily on massive deposits that must be mined underground. It is most applicable to weak or moderately strong ore bodies that readily break up when caved. Both block caving and longwall mining are widely used because of their high productivity.
