How Are Diamonds Mined And Extracted From the Ground
Alluvial mining involves the building of walls and the diversion of rivers. Once the water is emptied out and prevented from flowing into the area of interest, bulldozers are then used to exploit the ground of the riverbank. Usually, kimberlite ore can be found in depths of at least 15 meters. When the diamondrich depth is reached, the raw ...
