Main Steps Of Iron Mining

Aug 28, 2014 The Operational Land Imager (OLI) on Landsat 8 captured this image of iron mines in northern Michigan on September 11, 2013. Although the mined areas look like one facility from a satellite perspective, there are two separate mines in this scene. The Empire Mine, which produces about 5.5 million tons of magnetite each year, is on the east side.
