A common process for mining diamonds is to remove and process kimberlite ore. Kimberlite ore can be found in underground mines and open pits and often contains a small amount of diamonds that must be separated from the ore. The process of mining can require several months or longer, depending on the size of the mine. Keep Learning.

Open pit mining, underground mining, and seabed mining are the three most common ways to extract rough diamonds from Kimberlites. Polishing of Rough Diamonds. Once geologists identify a Kimberlite, they begin using one of the above mining methods to extract the diamond rich xenolith rock. Next, the diamonds need to be pulled from the xenoliths.
