There are mainly two kinds of mining done throughout the world to extract minerals, ore, crystals etc. These two are:

Open cast Mining:

• These kinds of mining are done in an open area. Heavy machinery is used to load and unload the minerals.

• It is costly as it requires specially designed lifts, drills.
