Manganese ore concentration npo-center

Manganese ore concentration There is a manganese ore concentration plant in Polunochnoje (North Ural) which was designed and built for entirely dry concentration processes. The use of this technology made it possible to receive a concentrate with 30% manganese content (up to 19% grade of mined ore), when it is extracted into the concentrate 79%, the grade of manganese in the tails is up to 8%.
