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.

Diamond to Ore Ratio - Soha Diamond Co.™

The ratio of diamond to ore is among the defining metrics that diamond mines use to calculate the return on investment before breaking ground on a prospective mine. The ratio calculates the average amount of ore (rock) that needs to be moved in order to yield diamonds. This ratio can vary based on geographic location and diamond mining techniques.
