Urals Aluminum Smelter (UAS)

The plant was built in 1939 to process bauxites mined in the Urals. The plant was upgraded and scaled up in 2015–2017. As a result, alumina production increased by 15% to 885.5 kt from the 770 kt produced in 2014.

The plant was the first to use new machinery in Russia such as Krauss Maffei disk filters, 3,300 m3 flat bottom decomposers with mechanical stirring, and a rotary calcination furnace.

Aluminium production has been mothballed at UAS under the 2012–2013 program for closing inefficient facilities of the Metals segment.

UAS uses the paralleled version of the Bayer and sintering processes. The Bayer part solely uses bauxite feedstock from the Sredne-Timanskoye bauxite deposit.

Development plans

The refinery aims to increase the efficiency of autoclave leaching and calcination furnaces to decrease power consumption and lower its carbon footprint.
