  • Mineral Exploration, how it's done

    Mineral exploration is the process of searching for evidence of any mineralisation hosted in the surrounding rocks. The general principle works by extracting pieces of geological information from several places, and extrapolating this over the larger area to develop a geological picture. Exploration works in stages of increasing sophistiion ...

    Magnetic methods are more popular in mineral exploration than gravity, not least because magnetic data can be quickly recorded from the air and in conjunction with other geophysical surveys. Land gravity surveys, by contrast, may require greater field efforts (Figs. 1, 5 and 6), more time, and more commitment of scarce capital.

    Surface mining is a form of mining in which the soil and the rock covering the mineral deposits are removed. It is the other way of underground mining, in which the overlying rock is left behind, and the required mineral deposits are removed through shafts or tunnels.. Surface mining is basically employed when deposits of commercially viable minerals or rock are found closer to the surface ...
