Coal comminution and sizing - ScienceDirect
2013-1-1 Vibrating screens can be operated either dry or wet, although since most coal preparation processes are water-based, coal screening on vibrating screens is generally done wet. They perform very well at the coarser sizes, but they are prone to blinding and damage when used for fine coal screening.

Coal based Direct Reduction Rotary Kiln Process – IspatGuru
2017-2-14 Coal based direct reduction process is based on the solid reducing agent which is non-coking coal. The reaction takes place at high temp (1000 deg C to 1100 deg C). Coal plays a dual role in the kiln. Part of coal is used as fuel to supply the desired heat so as to take the raw materials to the desired temperature.

Battle for Noront, capping coal prices and cutting emissions
2021-10-22 After the Chinese government asked state-backed firms to ensure stable coal and power supply “regardless of costs,” many coal producers have vowed to cap prices this winter, as reported by CNBC. This year’s thermal coal prices saw a surge of 200 per cent due to a series of factors including flooding in coal mining regions, anti-corruption probes and safety inspections.
