Advantages & Disadvantages of Limestone | HomeSteady
Limestone is a common rock composed of the mineral calcite. When these sea creatures die, their shells pile up into debris. Because it is a soft stone, it can discolor and scratch easily and can be etched if acidic liquids, like orange juice, are spilled on it. The material usually costs between $3 to $10 per square foot and it is strongly ...

Opencast Mining (Quarrying): Methods, Advantages & Disadvantages
Opencast mining or quarrying of minerals is easier than mining by underground methods. During quarrying the alluvium and rocks below which the minerals lie, are removed and dumped, in the initial stages, in a place which is not required in future for quarrying, residential or other purposes. The mineral exposed is completely extracted. Opencast ...
