Iron Mining In the Lake Superior Basin

Taconite is a lowgrade magnetic iron ore. When highgrade iron ore was plentiful, taconite was considered a waste rock and was not used. But as the supply of highgrade 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
