The Mozley Laboratory Separator, also known as the Mozley Concentrating Table, is a batch-process device designed for the quick and efficient separation of mineral grains based on specific gravity and size. It is particularly useful for rapid amenability testing of ores for beneficiation. The unit typically handles 50-100g samples and is equipped with two interchangeable stainless-steel trays: a 'V' profile tray for separating 2 mm to 100 µm particles, and a flat tray for finer separations of 100 – 10 µm particles. Some versions, like the Multi-Gravity Separator (MGS), can handle particles from 5µm to 150µm. Key adjustable parameters include slope, speed, amplitude, and wash water. It is applied in separating minerals with close size ranges or specific gravities, scavenging precious metals from tailings, and pre-concentrating heavy mineral sands. The separator incorporates an improved shaking mechanism and a non-porous deck with a cyclic pulse of jigged water for effective stratification.
