The removal of silica thus allowed an increase in the iron content from an initial 25 to 35% to about 55 to 60% in the ore bodies. Mining of these ores was initially carried out in open pit mines, as shown below. The image below is of the Jackson Mine, near Negaunee. Later, when the easily-mined ores (those near the surface, see below) were ...
