A scrubber in diamond processing is best described as:

A scrubber in diamond processing is best described as:

• A. A device that magnetizes ore
• B. An apparatus that washes away dirt and clay from diamond-bearing ore
• C. A means of grinding ore to fine powder
• D. A container used to store diamonds

Answer: (B)

This question tests what a scrubber does in diamond processing. A scrubber is an apparatus that uses water and agitation to loosen and wash away dirt and clay from diamond-bearing ore. By breaking up clays and removing fine earthy material, it cleans the ore so that the heavier diamonds can be separated more effectively in later steps. It isn’t a magnetizing device, which would target magnetic minerals; it isn’t a grinder that turns ore into powder; and it isn’t a container for storing diamonds. So the description that fits best is washing away dirt and clay from the ore.
