  • Artificial weathering of coal to enhance milling

    Abstract The mined coal need to be comminuted to use as source of energy or reducing agent. This study is carried out to explore a process inspired from nature to soften the coal to enhance the energy efficiency of milling. Coal samples were artificially weathered for different time duration (3 7 10 days) using solutions of different pH (2 7 12).
