accurately estimate iron ore grades and reserves, the geology and geochemistry of the subsurface must be mapped accurately. In resource evaluation at Rio Tinto Iron Ore, block models are created through drilling and interpreting RC holes (Sommerville et al., 2014). RC chips from these holes are logged and assayed in 2 m intervals.

The drill rods were solid, and the cuttings were removed by the plunging action of the drill. After the early 1870s all machines rotated their drill rods with a spiral "rifle bar" at the rear of the piston. At 60 psi of air pressure, these drills ran from 200 to 600 strokes and penetrated two to six inches per minute.

Secondly, the temperature data computed on the inner wall of the rotary kiln is used as a boundary condition to solve the problem of melting the solid material, thus determining the required melting time. The model is validated against experimental data for the melting of iron, the material currently used in the plant.

A rotary drill rig is one of two main types of drills used for mining. The other type is a percussion or hammer drill. For a rotary drill rig, the drill bit turns under pressure to cut into the rock. As the bit turns, the rock grinds down while compressed air sends it back up the drill to the top to keep the hole and bit clean.
