Centrifugal Gold Concentrator

Product Overview

Centrifugal concentrator is a high-tech equipment that utilizes the principle of centrifugal force to strengthen the gravity separation process, representing the advanced level of current gravity separation technology. The core of the machine generates a powerful centrifugal force field through a high-speed rotating conical enrichment cone, which enables the efficient recovery of micro-fine grained heavy minerals (e.g. gold, tungsten, tin, etc.). This equipment is especially good at capturing the micro-fine grained monomer gold that is easily lost in traditional re-election equipment (such as chute and jigger), with a recovery rate of more than 99% and an enrichment ratio as high as 1,000 times, which makes it an ideal alternative to amalgamation for gold extraction and realizes environmentally friendly gold extraction, and it is widely used in the reclaiming of rock gold mines, alluvial gold mines and tailings resources.

Core working principle

The slurry is fed into the bottom of the high-speed rotating enrichment cone from the upper part. Under the action of strong centrifugal force, the mineral particles are thrown to the grooves (ribs) of the cone wall.

• Heavy mineral particles (e.g. gold): the centrifugal force is so strong that they can overcome the resistance of the backwash water sprayed outwards from the grooves, and settle and concentrate in the grooves to form a concentrate layer.

• Light mineral particles, which are subject to less centrifugal force and cannot resist the scouring force of the backwash water, are carried out of the groove by the water flow and are discharged with the upward water flow from the upper end of the enrichment cone as tailings.
  The concentrate is discharged at regular intervals through the innovative automatic discharge system, realizing the automation and closed operation of the whole process.

Product Advantages and Features

• Extreme Recovery Performance: The recovery rate of monomer gold for micro-fine grains (-0.074mm) is up to 98%, and the enrichment ratio is up to 1000:1, which is far better than the traditional re-election equipment.

• Full-automatic operation: Equipped with automatic ore discharge system, one-key start and stop, no need to stop the machine for manual cleaning, eliminating the loss of gold particles caused by human factors, and greatly saving labor.

• Green environmental protection: the sorting process does not add any chemicals (such as cyanide, mercury), friendly to the environment, is a model of clean production.

• Energy saving and consumption reduction: less water consumption, low power consumption, wear-resistant wearing parts, very low operation and maintenance costs.

• Strong adaptability: Wide range of feeding concentration (0-50%), strong adaptability to particle size fluctuation, capable of processing both alluvial and rock gold ores.

• Stable and durable: Adopting soft connection damping technology, effectively suppressing vibration of the equipment and running smoothly, which not only improves the sorting precision, but also prolongs the service life of the equipment.

• Compact and Flexible: Modular design, small footprint, can be easily embedded in the existing beneficiation process after the mill or cyclone overflow.

Applicable Fields

• Gold Recovery: Recovery of fine-grained monomer gold in rock and alluvial gold ores; Recovery of gold in tailing ponds and re-election tailings.

• Replacement of amalgamation: completely eliminate the amalgamation method of gold extraction, which is harmful to the environment and individuals.

• Other Heavy Minerals: It can be used to recover other non-ferrous minerals with large specific gravity such as tungsten and tin.

• Process Optimization: Installed after the ball mill or at the hydrocyclone overflow, as a high-efficiency sweeping equipment to capture the "difficult to select" fine-grained minerals.
