How Are Diamonds Mined And Extracted From the Ground

To make mining efficient and effective, the raw rock and soil are typically not examined on-site. 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.

Ore sorting - Preceding processing Ausenco.

“This requires that the cost of mining, sorting and ore storage is low and implemented without major capital and operating cost impacts,” he said. Re-scheduling a mine and process plan to produce a higher-grade product at the outset would be very appealing to investors, but it has to be balanced with the value over the entire mine life.
