Outotec to deliver two alumina calciners to Russia


Outotec has agreed with ZAO Komi Aluminium on the design and delivery of two alumina calciners for the Sosnogorsk Alumina Refinery in the Republic of Komi, Russia. The contract value exceeds EUR 20 million.

Outotec's scope of delivery covers the engineering, supply of special equipment and services for a calcination plant with two circulating fluid bed calciners. Each calciner has a capacity of 2,640 tonnes alumina per day. The total annual capacity of the new refinery will be 1.4 million tons of alumina.

The new calcination plant is expected to be operational by the end of 2008.

In the aluminum production process bauxite is first digested with caustic soda to extract and precipitate pure aluminum hydroxide, which is then calcined to alumina. Alumina is the main raw material in aluminum production.

Since 1968, when the first industrial plant for alumina calcination based on circulating fluid bed technology was designed in Germany by Lurgi, Outotec has delivered over 50 alumina calcining plants all over the world. These two units for Komi will, however, be Outotec's first alumina calciner deliveries to Russia.
