Taconite is a hard, dense rock containing a mixture of silicates and magnetite and is abundant on the Mesabi Range. New processing methods developed in the mid-20th century made taconite mining profitable. After it's mined, the taconite is crushed into a fine powder. The magnetite is separated with magnets and agglomerated into marble-sized ...
WhatsApp: +86 18221755073Taconite is a very hard, relatively low grade ore that forms the basis of the iron industry in Minnesota today. In 2005, six taconite companies were active, all of which mine on the Mesabi Iron Range.
