Metallurgical enterprises of the Metinvest mining and metallurgical group are currently operating at 75% capacity, said Metinvest's COO Oleksandr Myronenko. "The group managed to keep five blast furnaces in production - three at Zaporizhstal and two at Kamet Steel - and the entire range of rolled products. Metallurgists maintain such production volumes due to the fact that exports through sea ports have opened," Myronenko explained in an interview with thepage.ua.
