Vorkutaugol has received the quality certificate for the coal concentrate of a new grade – 1Zh. The company has also confirmed the quality of its other products – coal concentrate of grades K, 2Zh and GZhO.
The new certificate allows the company to sell the product.
“We started processing the 1Zh grade in trial mode in 2017, when the Vorgashorskaya mine opened the Southwestern block at its deposits. Since then we’ve accumulated enough experience to be able to manufacture quality products”, Pechorskaya processing factory manufacturing department director Edward Kabanov said.
The 1Zh grade coal is used in metallurgy. According to Cherepovets Iron and Steel Works tests, the new coal can improve the strength of coke by 15%. And when the 1Zh grade coal replaces GZhO grade coal in the charge, it decreases sulfur content in coke. (Ukrainian metal)
