Surface mining. Surface mining is exactly what the word says digging rocks out from the surface, forming a hole or pit. In South Africa, this method is used to mine for iron, copper, chromium, manganese, phosphate and coal. Surface mining is also known as open pit or open cast mining. An open pit coal mine.
Openpit mining is a surface mining operation whereby ore, or waste, is excavated from the surface of the land. In the process of digging the surface of the land, a deeper and deeper pit is formed until the mining operation ends. It is usually suitable to determine the final shape of the pit before the mining .
Feldspar Feldspar Chemical composition: All the rockforming feldspars are aluminosilie minerals with the general formula AT4O8 in which A = potassium, sodium, or calcium (Ca); and T = silicon (Si) and aluminum (Al), with a Si:Al ratio ranging from 3:1 to 1:1. Microcline and orthoclase are potassium feldspars (KAlSi3O8), usually designated Or in discussions involving their endmember ...

Most gemgrade corundum forms in metamorphic rocks or in igneous rocks. Mining small gems from hard rock is possible, but it is very expensive, and many of the gems are broken during the mining process. Fortunately, corundum is very hard and resistant to weathering. Rubies occur in corundums. Today, the gems are mined from the stream sediments.
