Ovoot metallurgical coal to address forecast fat

Fat coal creates conditions for good meltability, improving coke's wear strength and creates conditions for adding other coals with low coking capability. The Fenwei report indicates fat coal as a percentage of total Chinese coal blends is to rise from 13.6% to 14.7% over the forecast period resulting in a total fat coal demand of 76 million tpy.

Studies on the Possibility of Extending Coal Resources for

Bituminous coals with very good coking properties are basic components of the coal blends used for the production of the high-quality blast furnace coke. In industrial practice and on an international market, these coals are known as hard-type coals. Their appropriately high share in the coal blends ensures coke quality complying with the requirements of coke consumers.
