Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef or placer deposit.These deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.

Apr 24, 2017 · How Is Granite Extracted? Mining operations use different methods of cutting to extract the different deposits from the ground in places called quarries. These slabs are then polished, put on trucks and sent to fabriors. The fabriors will then cut the slabs into the appropriate sizes and length for commercial and home use.
Mining Technology (including, appliion of new methods, innovative techniques and development of technology for underground and open pit mining, research & development leading to increase in productivity, conservation ofmineral resources, systematic mine planning, concurrent mine reclamation & rehabilitation and dimensional stone mining)
It differs from the mining of ores of metals in that whereas quarrying is an operation carried out entirely on the surface, mining involves digging below the ground, sometimes at considerable depth. A quarry is a place where different types of stones are extracted. Selection of Site for Quarrying of Stones.

Branch mining is effective because you can acquire a lot of ores efficiently. However, this type of mining consumes many tools because of the volume of stone you dig through, and produces much more cobblestone than valuables. Branch mining is a helpful method if you have patience, and a project in which you can invest your fortune of cobblestone.
