Russian steelmaker Severstal has stated that a second dry magnetic separation unit (DMS) has been commissioned at Karelsky Okatysh, a major production and iron ore processing plant in Russia and part of the Resources Division of Severstal. The unit, which has received more than RUB 200 million ($6.35 million) investment, will enable Karelsky Okatysh to enhance operational efficiency.
Karelsky Okatysh’s use of DMS technologies directly at the edge of an open-pit mine where ore undergoes primary breaking is unique within Russian production.
The second DMS unit has been built, developing on experiences gained from the first unit, with a larger coarse-ore bin which facilitates loading from 136−mt dump trucks. An overhead crane has also been installed with the new unit to facilitate maintenance and repairs, and a modified vibration feeder has also been included. These and other innovations have significantly added to the output of the new unit; whereas DMS-1 processes 3 million mt of contaminated ore per annum, DMS-2 is capable of processing 4 million mt.
