A thorough investigation into the British Standard method for the determination of pyritic sulphur has shown that it is not suitable for all Australian coals, and that instead, the direct or non-simultaneous method should be adopted. Determinations of the iron which is not extractable with nitric ac
## Abstract A rapid and simple method for the determination of pyrite in coal, based upon a twoβstep extraction of iron from coal is presented. After milling the coal in a tungstenβcarbide vessel, the nonβpyritic iron is first removed and then the pyritic iron dissolved. This is then followed by AA
Burnout times of high-ash coals in a fluidized bed were determined for coal panicle sizes ranging from 0.125 to 4 ram, over a temperature range of 973-1173 K and fluidization velocities varying from 3.7Umf to 6.2U,,f. The results show that the mode with which anthracite particles burn resembles that
