  • Iron Mining In the Lake Superior Basin midwestadvocates

    Taconite is a low grade magnetic iron ore. When high grade iron ore was plentiful, taconite was considered a waste rock and was not used. But as the supply of high grade iron ore decreased, the mining industry began to view taconite as a resource. Eventually a process was developed to create taconite pellets by concentrating the low grade ore

    After many years of hard work, a process was developed to create taconite pellets. Taconite saved Minnesota's iron ore mining industry. To make these pellets, the hard taconite ore is blasted and then ground down with water to a fine powder. The fine iron rich particles, mostly of magnetite are extracted from the powder by use of magnetism.
