Extract Iron From Taconite

Vermilion Range. The bedrock, known as taconite, also contained iron, but in a much lower concentration. Eventually, the high-quality ore was mined out, and new processes had to be developed to extract the iron from the taconite. This was successful, and Minnesota's iron industry centered on the Mesabi Range, where the taconite was much easier to access.

Iron Range 101: What is taconite? Twin Cities Daily Planet

Taconite is a low-grade iron ore. Originally thought to be of little value, taconite was considered overburden (waste) in the days when high grade iron ore was mined. The iron content, magnetite, is only 20- 30% compared to 50 60 % iron content in red ore. Red ore is also referred to as direct shipped ore because it can be shipped without processing.

The processes of iron extraction and formation, go through several stages as follows: Blasting or blasting. To extract iron from the ground, Taconite rocks are detonated using explosives, due to the rigidity and hardness of this type of rock. The taconite is a new sedimentary rock, a variety of iron formations. Transportation

Iron Mines in Michigan NASA

Today, mine operators in Michigan’s Upper Peninsula are generally after taconite, a low-grade ore that was once considered waste rock. To make it usable, mining companies blast it into small pieces with explosives, grind it into powder with powerful machinery, and then use magnets or flotation techniques to separate the iron minerals out from the surrounding rock.
