May 27, 2020 Mining remains an essential and growing part of the modern industry. By some estimates, it makes up nearly 45% of the total global economy, and mineral production continues to increase as demand for raw materials grows around the world.. However, many mining techniques still in use can have serious impacts on both the mining site itself and the surrounding environment.
Mining of this particular gem is a simple and harmless process in which the metamorphic rocks that contain aquamarine are first split into pieces by inserting air/gas pressure into the rocks. Moreover, even after exhausting, the mines are not left barren. A 2m to 4m thick soil layer is placed over the filled and closed mine pits.
