MECHEL REPORTS IMPLEMENTING NEW COAL WASHING TECHNOLOGY AT ELGA COAL COMPLEX

Moscow, Russia – August 8, 2014 – Mechel OAO (NYSE: MTL), one of the leading
Russian mining and metals companies, reports implementing a new coal washing and
dewatering technology at Elga Coal Complex’s seasonal washing plant. Investment
in this project totaled some two million US dollars.
The launch of two membrane filter presses produced by Tecnicas Hidraulicas will
enable the complex to filter slime waters under pressure and make intensive
mechanical dewatering of small coal fractions. This technology will boost the
seasonal washing plant’s end-product capacity by 10% (from 2 million tonnes to
2.3 million tonnes annually) and reduce the facility’s consumption of process
water by 2.5-3 times.
Currently work still continues on transferring Elga’s seasonal washing plant to
all-year operation mode. The works are scheduled to be completed in
October-November, which will enable the plant to reach 2.7-million-tonne annual
capacity.
The new technology enables the plant to loop the ultrafine coal and clarified
water system and fully exclude the possibility of waste waters getting into
external hydraulic facilities. This complies with the ecological safety
requirements as set in the Russian environment protection law.
 “Construction of Elga Coal Complex’s facilities is being conducted exclusively
with the use of state-of-the-art technologies that will enable us to make the
Elga project one of global leaders by its cost efficiency and profit. Besides,
we make maximum effort to increase the quality of our coal products, which is,
in our conviction, the project’s trademark,” Mechel OAO’s Chief Executive
Officer Oleg Korzhov commented.
