Ukraine-based mining and steel company Metinvest Group will invest over $92 million in the upgrading of the fourth blast furnace at its Mariupol-headquartered subsidiary Azovstal Iron and Steel Works, according to Azovstal's statement.
The overhaul of the blast furnace will last 120 days, starting in June 2014. Currently, tenders and contractor selection are in progress. Contracts are being concluded with equipment suppliers.
The company intends to increase the performance of the blast furnace by a quarter, up to 1.1 million mt of iron per year. Environmental protection equipment will be fully reconstructed.
