How Are Diamonds Extracted? | Bizfluent

To begin this extraction technique a pit is created; it is dug with steep sides to create a cone narrowing to a point that is connected by roads built into large mines. The large cone is called a kimberlite pipe. Material is removed in large quantities by dump trucks and large loaders. It is then sorted and cleaned at a nearby processing plant.

How Are Diamonds Mined And Extracted From the Ground

Instead, they are transported to special plants where the ore is processed and the rough diamonds are extracted. Depending on how rich the ore is, a few hundred tons of ore might be sieved just to produce a single carat of gem quality rough diamonds. Even after extraction, the rough diamond is still far from being set in an engagement ring.
