Extraction of Iron, Iron Mining, Iron Ore Processing

Hematite is easier to floated than magnetic, which could be separated by positive flotation. As the density of iron ore is much higher than that of gangue mineral, gangue mineral is more likely to attach to the than iron ore. Therefore, for the extraction of iron ore, reverse flotation is more advantageous than positive flotation.
