100 tph centrifugal gold separator

1.Product Introduction Gold Ore Processing Equipment

The 10tph to100 tph Centrifugal Gold Separator Centrifugal Gold Separator is a high-capacity gravity separation system designed for large-scale gold mining operations. The core technology utilized is the water-jacketed centrifugal concentrator (Knelson-type), suitable for processing gold-bearing materials with a particle size of less than 6mm from placer, vein, and tailings deposits. By generating a centrifugal force field 200–600 times stronger than gravity combined with a fluidization water system to prevent bed compaction, the equipment achieves high-efficiency capture of micro-fine gold (0.004–0.074mm) with recovery rates exceeding 97%. Leading models, such as the STLB-100, support fully automated continuous discharge with a single-unit capacity of 60–80 t/h. Multiple units can be configured in parallel to meet 100 t/h system requirements, making them ideal for stationary plants and large-scale mobile processing systems.

2.Application Gold Ore Processing Equipment

• Continuous Large-Scale Placer Mining: Ideal for 24/7 high-throughput gold extraction in riverbeds and alluvial fans, specifically optimized for industrialized centralized mining.

• Hard Rock Gold Pre-concentration: Serves as the primary gravity unit post-grinding to recover Gravity Recoverable Gold (GRG), reducing downstream cyanide leaching costs by over 30%.

• Tailings Resource Recovery: Large-scale scavenging of residual gold (grades 0.1–0.5 g/t) from historic tailings dams to maximize resource utilization.

• Environmental Remediation: Integrated into gravity enrichment stages prior to tailings dry-stacking to ensure gold loss remains below environmental thresholds (<0.01 mg/L).

• International Large-Scale Projects: Deployment of modular processing plants in regions like Africa and Central Asia, supporting skid-mounted integration and remote monitoring.

3.Working Principle Gold Ore Processing Equipment

• Slurry Preparation: Crushed and ground ore is conditioned into a slurry with a 30–50% concentration and pumped into a parallel feeding system for the centrifugal units.

• Centrifugal Enrichment: Conical rotors spin at high speeds (100–400 rpm), creating a powerful centrifugal field where high-density gold particles are flung toward and captured within the inner wall grooves.

• Fluidization Water System: Pressurized water (0.03–0.06 MPa) enters the water jacket via a hollow shaft and is injected through small holes in the inner wall, maintaining the concentrate bed in a loose, fluidized state to prevent compaction.

• Automated Discharge: The PLC control system triggers a high-pressure backwash sequence at preset intervals (1–4 hours), automatically discharging enriched concentrate into a collection tank.

• Multi-Stage Synergistic Circuit: Gravity tailings can be routed to flotation or shaking table systems for further recovery of residual fines, forming a "Gravity + Flotation" combined process.

4.Advantages Gold Ore Processing Equipment

• High Throughput & Scalability: With a maximum single-unit capacity of 80 t/h, two parallel units can easily meet a 100 t/h system requirement, allowing for modular expansion.

• Superior Recovery Efficiency: Achieves 97%–98% recovery for fine gold (0.01–0.074mm), significantly outperforming traditional sluice boxes (<60%).

• Fully Automated Operation: Integrated PLC controls and pneumatic/electric discharge valves enable "one-button" start/stop and 24/7 non-stop operation.

• Eco-Friendly: No mercury or cyanide used; zero risk of toxic wastewater, meeting international green mining standards.

• Low Operating Costs: Energy consumption is below 0.8 kWh/t. Key components are made of 304 stainless steel, with a service life exceeding 8,000 hours.

• Significant Economic ROI: For a 100 t/h system processing approx. 300,000 tons annually, a 20% increase in recovery rate can generate additional revenue in the tens of millions (depending on local gold prices).

• Seamless System Integration: Compact footprint allows for easy interfacing with crushing, grinding, and dewatering equipment within existing processing flows.
