How Diamonds Are Mined
We from time to time consider how the diamonds we wear came to us. Common diamonds, as contradicted to manufactured diamonds or fake diamonds, are mined from the earth. There are as of now two techniques for mining diamonds: Pipe Mining and Alluvial Mining.
At the point when pipe mining is utilized, the diamonds are separated from the earth through volcanic pipe/funnels. These are not man-made pipes. These are normal funnels in the ground. Shanks are put into the ground by the funnels, and passages are crashed into the most profound parts of the pipe. The diamonds are not sorted out at the mine. Rather, immense rocks that are brimming with diamonds are brought out of the mine and moved to a screening plant for partition.
The Alluvial mining strategy is done in riverbeds and on shorelines. Dividers are worked to keep down the water and the sand on the bank on the other hand shoreline is moved with a bulldozer until the level of earth that diamonds can be found in is come to. Once more, the precious stones are definitely not sorted here. Rather, the sand that contains the diamonds is bulldozed into trucks, and taken to screening plants.
