Currently MMK’s main iron-ore supplier is Eurasian_Natural_Resources_Corporation and their Long-term agreement runs until 2017.
MMK is 30% self sufficient with 70% coming from others like ENRC. They plan on producing 16mt of crude steel by 2014 so around 32mt of ore required. We can only hope they make an offer.
