Rotary drilling is mostly used to drill big holes in large quarries, open pit mines, petroleum extraction, and other fields. Fig. 7.6 shows a diagram of a rotary drilling system. There are two groups of big rotary drilling: (1) rotary crushing by high-point loading to the rock from three cones, as shown in Fig. 7.7 a, and (2) rotary cutting by shear force from drag bits, as shown in Fig. 7.7 b.

The extraction of iron ore involves surface (open-pit) or underground mining techniques (please refer to Chapter 7 (Stace, 2015) on Iron Ore Extraction Techniques).

The iron itself is usually found in the form of magnetite (Fe3O4), hematite (Fe2O3), goethite (FeO (OH)), limonite (FeO (OH).n (H2O)) or siderite (FeCO3). The process of mining consists of discovery of an iron ore deposit through extraction of iron ore and finally to returning the land to its natural state. It consists of several distinct steps.
