“The new drying system will improve the mine's performance by incorporating the use of the most modern technologies in air filtration and burner management. This will result in lower fuel consumption, operational and maintenance costs, as well as minimise particulate emissions,”
says Pavel Lezhnev, purchasing director at OAO Severstal, which is a leading vertically integrated steel and steel-related mining company with assets in Russia, the USA, the Ukraine, Latvia, Poland, Italy, Liberia and Brazil. Severstal's crude steel production in 2011 reached 15.3 million tonnes.
“New equipment will not only improve our performance, but also increase energy efficiency and environmental performance, which are also very important for us.”
Sales engineer Michael Schiefer at global product sales, Pyro, Mining and Construction, Metso, says: “Olkon's existing equipment for iron ore drying had reached its service lifetime. Olkon chose Metso to provide the best solution for its application, based on our ability to design and supply optimised drying technology with enhanced efficiency. Our longstanding relationship with Olkon, our ability to meet modern operational requirements and the close cooperation in the process design of this project also contributed to Olkon's decision to choose Metso as the supplier for the equipment. Furthermore, Metso was the only supplier with the ability to offer a very high-capacity single-line system," says Yuri Pedan, Key Account Manager, Russia, Mining and Construction, Metso.
Metso's drying system will dry high-grade iron ore concentrate at a rate of 625tonnes/hour in one processing line. The delivery consists of a direct-fired rotary dryer, including process and equipment design, firing system, air pollution control equipment, instrumentation, plant control system, and project management.
The delivery will be completed by the fourth quarter of 2013.
