Hoisting: The ore is then transported to the surface by ore elevators, called skip hoists. Each skip can carry 40 tonnes of ore at a speed of 60 kilometres per hour, or 17 metres per second. Processing The crushed iron ore is then processed above ground to either fines or iron ore pellets. It is a complex process that takes place in several stages:
Currently, the stripping ratio at active Minnesota iron ore (taconite) surface mining operations is at about 1:1. Based on the Biwabik Iron Formation's overall dip of 5-10° to the south in the area of interest, for every mile that mining progresses down-dip, the depth to ore increases by about 700 feet. Therefore, the ore zone (LC-4 and LC-3 ...
