    What is Coking Coal

    The Chinese coking coal market is likely to be the largest consumer for Ovoot coking coal due to its size and proximity. Premium coking coals such as Fat (Ovoot coal) and Primary coals, are in particular high demand within China primarily due to the low ratio of these coals in China's own coal reserves but also due to the growing requirement for higher quality coking coals in the coke industry.

    Sized coal. There are 4 main specifiions of coal for this direction. The first is standard Kuzbass blend having quality parameters common for the Kuzbass coal of high volatile. The second is High AFT Kuzbass blend which consists of slightly lower ash and AFT higher than the usual Kuzbass coal. The third specifiion is – Low CV type.



    mill. A 50gram sample of prepared coal of uniform size range is placed inside a grinding unit. The unit undergoes a standard number of revolutions under a specified pressure allowing steel balls within the unit to crush the coal sample. The coal fines are sorted and the quantity of coal less than a specified size is



     · The standard practice on coal in England has been to use celltocell "SubA" Flotation Machines of the double overflow type. Several hundred of the large No. 30 cells (100 cu. ft./cell) are in use. Supercharging is not generally used. Flotation is carried out .
