OpenPit Mining. Compared with underground mining, an openpit mine is usually less expensive. Unlike underground mining, equipment size is not restricted by the size of the opening to the mine and consequently openpit mining can take advantage of economies of scale, using larger and more powerful shovels and trucks.

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.

mining: Openpit mining Deposits mined by openpit techniques are generally divided into horizontal layers called benches. The thickness (that is, the height) of the benches depends on the type of deposit, the mineral being mined, and the equipment being used; for large mines it.

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 ...

equipment selected. Moreover, equipment selection directly affects the pit design and production planning. In open pit mining, equipment selection is made according to many factors related to the ore and mining conditions. These factors can be qualitative and quantitative in nature. The main purpose of equipment selection is to choose the

outside the mining area for placement and storage. In the Midwest, where the surface topography and coal seams are generally flat, it is common to employ area strip mining in which the fragmented overburden is placed directly by large draglines in the space created where coal has been mined ().In some situations in the eastern United States, a coal seam occurring near the top of mountains is ...

The Mining Process. The Mining Process. 1. Mining – open pit and underground. To define the ore from the waste rock, samples are taken and assayed. Assay results are used to mark out areas of ore and waste rock, which are mined separately. Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers.
