- Process Of Quarrying Iron Ore
Iron ore was chosen for this study due to the significant amount of this ore mined annually in Australia, as shown in Figure 20.2 over time. Since 2009, the production of iron ore from Australia has risen significantly. The percentage of global production and reserves for the major iron ore-producing countries for 2010 is shown in Figure 20.3 ...

Open-pit mining differs from quarrying (with the possible exception of iron ore) in that the valuable mineral constitutes only a small proportion of the total tonnage of rock produced. In quarrying, the rock itself is the valuable commodity, with virtually all of the raw rock that is won being processed (often only by crushing and screening) to ...
