Frontiers | Basic characteristics and environmental impact of iron ore …
We can see that the iron in IOTs is mainly in the form of silicate iron and the distribution rate of iron is 81.29%. Then come the magnetite and carbonate with the iron distribution rate of 7.43% and 3.37%, respectively. In this case, the IOTs used for our study are the tailings with high silicate iron.
