Problems and Solutions in Open Pit Iron Ore Mining
25/05/2021 Usually in the open pit iron ore mining production will use electric shovel excavator to load the ore This kind of equipment is relatively large, and the driving density is relatively high during the mining process In addition, the slope in the mining area is steep, and the load capacity is relatively large during the transportation of iron oreOpen pit mining refers to mining directly on the ground surface, thereby producing an open pit This method is practical and costeffective when the uranium ore is located near the surface (eg, within 100 m) Underground mining and ISL methods may be considered for sites that have uranium ores at deeper depthsOpen Pit Mining an overview ScienceDirect Topics22/02/2022 Openpit mining is commonly used to extract metallic ores like aluminum, bauxite, copper, gold, copper, and iron as well as nonmetallic ores like coal, uranium, and phosphate Openpit mining isWhat Is OpenPit Mining?
