    An Overview of the Open Pit Mining Process

    Mar 02, 2016 There are two types of mining methods commonly used in large scale mineral mining; open pit mining and tunneling. Open pit mining is used when the minerals to be mined are located just close to the surface. This is especially when the soil or material covering the minerals are relatively thin and can easily be moved for the mining to take place. Open-pit

    An open pit mine is typically excavated with a series of benches to reach greater depths. Open pit mining initially involves the removal of soil and rock on top of the ore via drilling or blasting, which is put aside for future reclamation purposes after the useful content of the mine has been extracted. The resulting broken up rock materials are removed with front-end loaders and

    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

    Jun 22, 2018 The next step, once the ore is excavated, is to separate the waste rock and ore using primary crushers, located at the open pit mine site. At this point, larger rocks are broken down to a size better suited for the conveyor belt to transport. From there, the ore is transported to a separate facility for smelting, which is:
