What is recovery in diamond processing?

• A. A method used to separate diamonds from ore or alluvial sediments
• B. A device that heats diamonds
• C. A measurement of diamond carat weight
• D. A chemical used in cutting diamonds

Answer: (A)

Recovery in diamond processing is the stage where rough diamonds are separated from the surrounding rock, ore, or alluvial material after mining. This is the step that makes the diamonds collectible for further processing and sale, using methods that exploit differences in density, size, or shape to pull diamonds out from waste material. In most operations, material is washed, screened, and then subjected to gravity-based or optical separation to isolate the diamonds from barren material. Heating, carat weight, or chemicals used in cutting are not about pulling diamonds out of the material themselves; they serve other roles in handling, measuring, or shaping rather than the extraction step.
