After the commissioning of the full processing cycle at the washing plant first volumes of the coking coal concentrate were produced.

The plant’s processing capacity is up to 3 million tonnes per annum. The CAPEX is approx. 2 billion rubles (about $ 64.7 mn*).

Following the completion of railway connecting the deposit with Baikal-Amur Mainline the launch of washing facilities allows to mine and process coal at Elga open-pit on production scale and start receiving benefits from vast investment in the project development.”, said Igor Zyuzin, Chairman of the Board of Directors of Mechel OAO.
