    ExtractionRehabilitationTypical Open Cut GradesReflection QuestionsOpen-cast mines are dug on benches, which describe vertical levels of the hole. These benches are usually on four to sixty meter intervals, depending on the size of the machinery that is being used. Many quarries do not use benches, as they are usually shallow. Most walls of the pit are generally dug on an angle less than vertical, to prevent and minimize damage and danger from rock falls. This depends on how weathered the See more on courses.lumenlearning

    steps on open pit mining for iron. 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.

  • steps on open pit mining for iron

    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. get price

    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:
