what is the difference between an open pit mine,

Open cast mining is used where the resource is near the surface and widespread - examples are iron ore, bauxite and any other deposit that is near the earth's surface. A deposit which has a limited areal extent and/or is very deep will be mined by undergroung mining. This is more expensive, so is only justified where the grades are good.
