Krasnoyarsk Metallurgical Plant (KraMZ)
total capacity and utilisation rate, 102%
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.
The refinery aims to increase the efficiency of autoclave leaching and calcination furnaces to decrease power consumption and lower its carbon footprint.
