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.

The mining of columbite/tantalite (COLTAN) has a negative effect on the different spheres of the environment notably; hydrosphere, lithosphere, and the atmosphere (Eisler 2004). Just like gold mining, COLTAN extraction involves the breaking of crystallographic bond in the mineral ore to get the products in the pure form.

In open pit mines the coal is extracted after having removed the rocks above. In the case of underground mines, the extraction is carried out in two ways: the method of “abandoned pillars” and that of “long faces”. The first method consists in extracting coal while leaving “pillars” to support the roof of the mine.
