  • 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 blastingThe deep mining of iron ore is unusual in the modern era, but in northern Sweden, ore is mined from considerable depth largely aided by the application of automation and remote control equipment Kiruna has been chosen as the example for a more detailed review ofIron ore extraction techniques ScienceDirectAt present, iron ore resources are decreasing day by day, which is characterized by more lean ore than rich ore, more associated ore and complex ore composition Xinhai Mining, as a mineral processing equipment manufacturer with over20year experience, provides responsible iron ore processing technologies by different type of iron oresExtraction of Iron, Iron Mining, Iron Ore Processing
