How To Mine Diamonds
Have you ever thought where diamonds come from? It is common that we do not think about how the diamonds we wear came to us. For natural diamonds, as opposed to synthetic diamonds or fake diamonds, are mined from the earth. In the current technology, it has two methods of mining diamonds: Pipe Mining and Alluvial Mining.
What is pipe mining? The method of using pipe mining will be the extracted of the diamonds from the earth through volcanic pipes. Do note that these are not man-made pipes. All these are natural pipes in the ground. Shanks are put into the ground next to the pipes, and tunnels are driven into the deepest parts of the pipe. When the diamonds are being mined, they are not sorted out at the mine. Instead, huge rocks that are full of diamonds are brought out of the mine and moved to a screening plant for separation.
As for the second method of alluvial mining, it is done in riverbeds and on beaches. Solid walls are built to hold back the water and the sand on the bank or beach is then moved with a bulldozer until the level of earth that diamonds can be found in is reached. Once again, the diamonds are not sorted on the spot. Instead, the sand that contains the diamonds is bulldozed into trucks, and taken to screening plants.
