Types of Iron Ore: Hematite vs. Magnetite_SMM

2013-9-7  In particular, mining companies focus exploration and development on the iron-rich Labrador Trough. Magnetite ore’s most distinctive property is its magnetism. It is the most magnetic mineral in the world. Additionally, obtaining iron from hematite ore can produce a great deal of carbon emissions, and the process for magnetite is much less harmful. The product from magnetite ore is also of higher

Magnetite Ore, Magnetite Iron Ore, Iron Ore Mining

It is commonly formed by the reduction of hematite and ferric hydroxide minerals in these rocks. Banded Precambrian iron formations commonly contain magnetite ore. Magnetite is characteristically recognised by its strong magnetism, colour and streak. It is commonly used in magnetic separation and coal washing. However, it is not limited to these purposes, as its abundance and magnetic properties
