Gold Centrifugal Concentrator
The Centrifugal Concentrator is a mineral processing device that utilizes centrifugal force to enhance gravity separation, widely employed in recovering fine-grained minerals such as gold, silver, tungsten, tin, and rare earth elements. Compared to traditional gravity separation methods (e.g., shaking tables, sluices), centrifugal concentrators operate in a high-G force environment (50–300G), significantly accelerating the settling velocity of fine particles and improving recovery rates, making them ideal for concentrating low-grade and ultra-fine ores.
Capacity: 0-60 tph
Feeding Size: 0-6 mm
Process Material: Alluvial gold, rock gold after grinding, and other precious metals.
Gold Centrifugal Concentrator Overview
The Gold Centrifugal Concentrator is a brilliant gravity separation equipment widely used in the mining industry, especially for placer gold, fine-grain rock gold, and other precious minerals.
Gold Centrifugal Concentrator Types
- Timed automatic discharge centrifuge, customizable, higher efficiency, higher price.
- Non-automatic discharge centrifuge, commonly used, in stock, manually stops working and takes out the gold concentrate after a few hours of operation. We have both in industry-type and laboratory-type small centrifuge.
- We customized fixed centrifugal and mobile concentrators (mobile gold wash plant usually equipped with portable trommel screen, portable gold centrifuge, portable gold shaker table, etc).
The gold centrifugal concentrator is used in combination with the vibrating chute, gold shaker table, gold wash plant, and other gold extraction equipment to increase the fine gold recovery rate.
Advantages
Gold Centrifugal Concentrator Advantages
The gold centrifugal concentrator delivers outstanding recovery rates and a high concentrating ratio, maximizing gold extraction efficiency. Its innovative center discharge design ensures secure and rapid concentrate removal, streamlining operations. As an eco-friendly solution, it operates without hazardous reagents or chemical additives, thereby reducing environmental impact while requiring minimal energy and water consumption—ideal for sustainable mining practices. Built with durable wear-resistant components, the system ensures longevity with straightforward maintenance. With an exceptionally fast return on investment—often achieving payback in under six months—it stands as a cost-effective and high-performance solution for both small-scale and industrial gold mining operations.
✔ High Recovery of Ultrafines (>90% for micron-scale gold)
✔ Effective for Low-Grade Ores (applicable to <0.1 g/t Au)
✔ Water & Energy Efficient (70% less water than sluices)
✔ Modular Design (scalable via parallel units for large-scale plants)
Structures & Working Principle
Gold Centrifugal Concentrator Structure
The main parts of a centrifugal concentrator are Feeding, rotor, groove, motor, backwash water, PU lining plate, bearing, frame, tailings concentrate discharge, etc.
Gold Centrifuge Principle
The rotor of the centrifuge rotates at a high speed. Under the action of centrifugal force, heavy minerals are stacking on the inner plate groove of the rotor core, and the light ore particles are gradually discharged. After about 4-6 hours of operation, stop feeding, and turn on the backwater to wash out the gold concentrate.
Gold centrifugal concentrator is useful in the gold recovery in all ranges of particle size. It is most especially useful for recovering fine gold which gets lost during the operation of gravity concentrators. The application has shown that the recovery of gold can be very high, as much as 99% and the concentration ratio is up to 1,000 times. In the recovery of natural gold in lode ore that has a particle size of -0.074mm, the gold recovered is about 98%, for recovery of gold in particle size of 0.004mm, it is up to 97%.
