Anthracite mined at the Kolyvansky coal deposit in Novosibirsk region possesses the best physical and chemical characteristics among all anthracites. It is classified as Ultra High Grade (UHG) anthracite, and has 92% carbon content - which is the highest one for premium quality anthracites. It also has a low level of impurities, such as sulphur, phosphorus, nitrogen, and others. The product is used primarily in metallurgy.
Sibanthracite produces two types of UHG anthracite: fines and lumps. The equipment and technologies used at the production sites make it possible to wash anthracite grades from 150 mcm up to 80 mm, and to produce 0-13 mm grade, high quality anthracite.
