  • Iron Ore Mining Techniques Metal Extraction

      Mechanized mining is executed by the extraction of iron ore from surface deposits The mining areas require all the operations to be mechanized and mining is exceptionally done through systematic formation of benches by drilling and blasting The physical processes are followed which then remove impurities and the processed ore is stockpiled
