Gravity sorting is a process used to:

• A. Sort by color
• B. Dissolve minerals
• C. Identify microdiamonds
• D. Separate heavier materials (diamonds) from a test sample

Answer: (D)

Gravity sorting works by using differences in density to separate materials in a mix. Diamonds are denser than most surrounding minerals, so when the sample is run through gravity-based separation equipment, the heavier diamonds behave differently from lighter gangue. This allows the heavier material, including diamonds, to be collected separately from the lighter material, effectively concentrating the diamonds from the test sample. It’s not about sorting by color, dissolving minerals, or identifying microdiamonds on the spot—the technique relies on density and particle behavior under gravity to achieve separation.
