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.

Natural stone must be carefully quarried and preferably removed as large blocks. The first step is to take down the "primary block", which is a large dimensioned chunk of rock loosened from the quarry wall. This is most often achieved by drilling, blasting or/or sawing. A primary block can vary in size depending on the stone type, and up to 1000 cubic metres, 2700 tons!
