Water Jacketed Centrifugal Gold Concentrator Centrifugal Gravity Concentrator

Water Jacketed Centrifugal Gold Concentrator

1.Product Introduction Gold Ore Processing Equipment

The Water-jacketed Centrifugal Gold Concentrator is a high-efficiency gravity separation system specifically engineered for the recovery of micro-fine free gold from ore. By generating a centrifugal force field hundreds of times stronger than gravity, the equipment significantly enhances the density-based separation of minerals. It achieves a recovery rate of over 97% for fine-grained gold with particle sizes ranging from 0.004mm to 0.074mm. It is widely utilized in placer gold, hard rock gold, and tailings re-selection applications.

2.Application Gold Ore Processing Equipment

• Placer Gold Purification: Ideal for gold panning operations in loose ore bodies such as riverbeds and alluvial deposits; particularly suited for mobile field deployment.

• Hard Rock Gold Pre-concentration: Applied in the post-grinding stage to prioritize the recovery of Gravity Recoverable Gold (GRG), thereby reducing downstream cyanide leaching costs.

• Tailings Resource Utilization: Efficiently recovers residual gold (grades 0.1–0.5 g/t) from historic tailings, maximizing comprehensive resource utilization.

• Environmental Remediation Projects: Used for gravity enrichment prior to tailings dry-stacking to reduce gold loss to levels below environmental standards.

• Small-scale & Artisanal Mining: Features a compact structure and low investment threshold ($3,000 – $15,000 USD), making it suitable for use in Africa, Southeast Asia, and remote regions.

3.Working Principle Gold Ore Processing Equipment

1.Slurry Feeding: Slurry with a concentration of 30–50% is injected from the bottom into the high-speed rotating conical rotor.
2. Centrifugal Enrichment: The rotor operates at a centrifugal force of 200–600G, flinging high-density gold particles toward the inner wall grooves where they are captured.
3. Stratified Tailings Discharge: Light-density gangue is carried by the water flow and overflows from the top, achieving effective separation.
4. Periodic Concentrate Discharge: After every 1–4 hours of operation, the system automatically pauses, and backwash water flushes the enriched gold concentrate into a collection tank.
5. Multi-Stage Synergy: The unit can be paired with shaking tables or flotation machines to further recover any remaining micro-fine gold.

4.Advantages Gold Ore Processing Equipment

• Ultra-High Recovery Efficiency: Achieves 97%–98% recovery for fine gold (0.01–0.074mm), significantly outperforming traditional sluice boxes (<60%).
• Eco-Friendly & Pollution-Free: Purely physical beneficiation with zero toxic reagents, meeting international green mining standards.
•  Low Energy & Operating Costs: Unit energy consumption is below 0.8 kWh/t; the system is easy to maintain with a critical component lifespan exceeding 8,000 hours.
•  Modular & Customizable: Supports semi-automatic or fully automatic control and can be integrated into skid-mounted systems, adapting to both stationary and mobile processing plants.
•  Significant Economic Benefits: Using a 50 t/h unit as an example, annual gold recovery can reach 1.5–3 kg, with an investment payback period typically under 12 months.
•  Strong Adaptability: Capable of processing ores with high mud content and complex particle size distributions, suitable for various geological conditions and ore types.
