Fine Gold Concentrator 5TPH-200TPH Fine Gold Recovery Equipment

Fine Gold Recovery from Tailings

1.Product Introduction Gold Ore Processing Equipment

FFine Gold Recovery Concentrator from Tailings is a gravity-based separation system specifically engineered to extract micro-fine gold (particle size <0.074mm) from mineral processing tailings. The core units include Knelson-type Knelson Concentrators (Water-Jacketed), Horizontal/Vertical Centrifuges, and High-Frequency Shaking Tables. Utilizing physical density separation for reagent-free enrichment, these systems are widely deployed in resource recycling projects for gold, iron, and copper tailings dams. Leading domestic models, such as the STLB-80 Knelson Concentrator, High-Rotation Water-Jacketed Centrifuge, and Jieko Vertical Centrifuge, feature fully automated discharge, modular integration, and low energy consumption. They support customizable throughput capacities (0.6–200 t/h) and are compatible with both stationary plants and mobile platforms.

2.Application Gold Ore Processing Equipment

Fine Gold Recovery Concentrator from Tailings

• Gold Tailings Re-selection: Scavenging residual fine gold (grades 0.1–0.5 g/t) from historic tailings dams to maximize comprehensive resource utilization.

• Cyanide Residue Pre-treatment: Recovering coarse gold via gravity separation prior to cyanide leaching, reducing cyanide reagent consumption by over 30%.

• Polymetallic Tailings Enrichment: Simultaneous recovery of high-density associated minerals such as tungsten, tin, and ilmenite from tailings.

• Environmental Remediation: Integrated into the front end of tailings dry-stacking systems to reduce gold content in discharge water to environmental standards (<0.01 mg/L).

• Small-scale & Artisanal Mining: Compact units (such as Guobang Horizontal Centrifuges) support standalone operation with low investment thresholds (<$5,000 USD), ideal for deployment in remote regions.

3.Working Principle Gold Ore Processing Equipment

1. Slurry Pre-treatment: Tailings are thickened to a concentration of 40–50% and screened for large impurities before being pumped into the centrifuge inlet.

2. High-Speed Centrifugal Enrichment: The drum rotates to generate centrifugal forces of 300–600G. High-density gold particles are flung into the cone wall grooves, while light-density gangue overflows from the top.

3. Periodic Concentrate Discharge: After a cycle of 1–4 hours, the system automatically pauses. Backwash water flushes the enriched gold concentrate from the grooves into a collection tank.

4. Multi-Stage Synergistic Operation: Gravity tailings can be routed to flotation machines (e.g., SF-type) using collectors like Potassium Butyl Xanthate (PBX) to capture remaining fines, achieving a "Gravity + Flotation" combined recovery.

5. Automated Control: Units equipped with PLC systems manage automated feeding, timed discharge, and fault alarms, with support for remote monitoring.

4.Advantages Gold Ore Processing Equipment

•  Ultra-High Recovery: Achieves 90–98% recovery for fine gold (0.01–0.074mm), significantly outperforming traditional sluices (<60%).
•  Zero Chemical Additives: The gravity process eliminates the need for cyanide or mercury, complying with "Green Mine Construction Specifications."
• Low Operating Costs: Energy consumption is below 0.8 kWh/t, with long maintenance intervals (critical component lifespan >8,000 hours).
• Modular Integration: Seamlessly interfaces with crushing, grinding, and dewatering equipment to build integrated "Tailings–Recovery–Dry Discharge" systems.
•  Strong Policy Alignment: Responds to national "14th Five-Year Plan" policies for tailings resource utilization, helping enterprises qualify for resource subsidies.
• Rapid ROI: Using a 50 t/h unit as an example, annual gold recovery of 1.5–3 kgtypically results in an investment payback period of <12 months.
