The Fe content varies from 0.03 wt to 18.6 wt with average of 2.7 wt for all types of Mn ore.Sep 17, 2015 As a result, a number of high-cost iron ore mines have been closed and suspended throughout the world in 2014, with up to 30 of low-grade iron mines shut down in China in 2014 alone.
1. Iron ore - supply and demand outline 1.1 Types of iron ore Iron ores can be classified in different ways. The most important has to do with the iron content.
