  • How is coal mined and extracted | Plan猫te 茅nergies

    Underground Mines Are More Common. After the coal is brought up to the surface by conveyors, it undergoes a process that removes sand and mud by immersing the coal in a solution of water and tiny magnetite particles. The different elements separate naturally. The coal floats while the other ores, called tails, sink to the bottom.
