    Mesabi Range Wikipedia

    In the early years of mining from the late 19th century until the 1950s, mining focus was on high grade ore that could be processed into steel without much change. However, when that supply dried up, focus shifted to lower-grade ore ( taconite ) which requires extensive processing at large mining-processing facilities before moving to port.

    The mining companies also pay an occupation tax and a royalty tax. The Taconite Tax Law exempts taconite operators from paying the ad valorem tax and provides that they be taxed by production only. This is important, since taconite mining and processing require the moving of three tons of crude ore for every ton of iron ore produced.
