ArcelorMittal announces it has signed a memorandum of understanding to establish a joint venture with Turkish partner Dayen to build a steel mini-mill with electric furnace in Sulaimaniyah in Northern Iraq.

The mill would produce in its initial phase up to 250,000t per year of rebars from locally sourced scrap and require investment of USD 100m to USD 130m, jointly subscribed by ArcelorMittal and Dayen.

Construction is planned to start in the second quarter of 2010 and production is planned to commence early in Q4 2011. Production could eventually increase to 500,000t per year.

"There are many opportunities for ArcelorMittal to assist in the development of the country," said Christophe Cornier, member of the Group Management Board. "There is great demand for steel products for the local construction industry, which we aim to meet, working closely with our partner Dayen and the local government in Northern Iraq".
