Iron ore (coarse grade) Manufacture Current magnetite production is a by-product of the copper operations and as such is recovered from the Concentrator floatation tails stream by magnetic separation. Approximately 15%, by weight, of magnetite is removed by 'cleaning' and 're-cleaning' of the magnetic concentrate from the first stage.

Use of Magnetite as an Ore of Iron. Most of the iron ore mined today is a banded sedimentary rock known as taconite that contains a mixture of magnetite, hematite, and chert. Once considered a waste material, taconite became an important ore after higher grade deposits were depleted. Today's commercial taconites contain 25 to 30% iron by weight.
