Open-pit mining refers to mining in the open space with mining, loading and transportation equipment according to the occurrence conditions of ore deposits. Some deposits are large in scale, shallowly buried, and even exposed on the surface. For this type of deposit, as long as the overlying rock layer and part of the surrounding rock are stripped off, useful minerals can be directly excavated

Surface mining is a process whereby soil and rock overlying the mineral deposit are removed. There are two principle types of surface mining, strip mining and open-pit mining (see Fig. 8.8).Strip mining is the process of mining a seam of mineral by removing a long strip of overlying soil and rock.

In a conventional open-pit mine or quarry, primary crushing is often synonymous with a parade of loud dump trucks driving around, generating dust, noise and consuming excessive amounts of fuel. A drill-and-blast team blasts the shot and develops a muck pile. A front-end loader, hydraulic shovel or backhoe excavator at the muck pile loads the dump trucks, which transport the rock to a fixed

In-Pit Crushers; the Key to Hard-Rock Conveying. The essential task of the in-pit crusher in a belt conveyor transport system is to reduce blasted material to a conveyable size. Crushers for this purpose are almost exclusively of the low crushing ratio type (up to 1 : 10), i.e. so- called primary or pre-crushers, designed as mobile or semi

The laterite mining method generally uses open-pit mining. The ore body generally does not require rock drilling or blasting. Nickel ore processing plant can directly use the excavator to shovel the ore. The thinner ore layers are first collected by the bulldozer and then shovel. nickel mining is divide into copper-nickel mining and extraction of nickel from sulphide ore.
