  • Mining of Iron Ores – IspatGuru

    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 methodsThe 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 diggersThe Mining Process – Waihi GoldOpenpit Mining Openpit mining, also known as opencast mining, opencut mining, and strip mining, means a process of digging out rock or minerals from the earth by their elimination from an open pit or borrow The word is used to distinguish this type of mining fromOpen Pit Mining Techniques|Surface Mines|Rock or Mineral

  • Openpit mining Wikipedia

    Openpit mining causes changes to vegetation, soil, and bedrock, which ultimately contributes to changes in surface hydrology, groundwater levels, and flow paths Additionally, openpit produces harmful pollutants depending on the type of mineral being mined, and the type of mining processOpen 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 coalBasics of an open pit mineOpenpit mining – General Overview Openpit mining (also known as opencut mining or opencast mining ) is a type of strip mining in which the ore deposit extends very deep in the ground, necessitating the removal of layer upon layer of overburden and ore Openpit mining – General Overview Protect Ecuador
