Quarrying of Stones Its Methods, Selection of Site

In these methods, blocks of rocks are broken loose from their natural outcrops by men using hand tools or special purpose channeling machines. No explosive material is used at any stage in this method of quarrying of stones. Soft rocks and also those rocks which have layered structure are easily quarried by these methods.

dolomite extraction process

Dolomite, also known as dolostone and dolomite rock, is a sedimentary rock composed primarily of the mineral dolomite, CaMg(CO 3) 2 Dolomite is found in sedimentary basins worldwide It is thought to form by the postdepositional alteration of lime mud and limestone by magnesium-rich groundwater Dolomite and limestone are very similar rocks.
