Falcon vs Knelson Concentrator: A Comprehensive Comparison

When it comes to gravity concentration equipment in mineral processing, two names stand out: the Falcon and the Knelson concentrator. Both are highly efficient at recovering fine gold and other minerals, but they differ in design, operation, and performance. This article delves into a detailed comparison of Falcon and Knelson concentrators, helping operators and investors make informed decisions.

Overview of Falcon Concentrators

Falcon Concentrators, produced by Sepro Mineral Systems, utilize high-speed centrifugal forces to separate fine minerals. There are various models of Falcon concentrators, including the SB (Semi-Batch), C (Continuous), and UF (Ultra-Fine) series, each designed for specific applications.

Key Features of Falcon Concentrators

  1. High G-Force: Falcon concentrators operate at a higher G-force (up to 300 G) compared to traditional concentrators, improving recovery rates especially for fine and ultra-fine particles.
  2. Versatility: Available in different models to suit a range of processing needs, from small-scale to industrial applications.
  3. Ease of Maintenance: Designed for easy disassembly and cleaning, reducing downtime.

Overview of Knelson Concentrators

Knelson Concentrators, developed by Knelson Gravity Solutions and now a product of FL, are renowned for their high recovery rates and robustness in mineral processing applications.

Key Features of Knelson Concentrators

  1. Lower G-Force: Operates at around 60-70 G, which is sufficient for most gold recovery applications.
  2. Proven Performance: Over decades, Knelson concentrators have built a reputation for consistently high recovery rates.
  3. Batch Operation: Typically operates in batch mode, suitable for small to medium-scale operations.

Performance Comparison

Recovery Rates

  • Falcon: Excellent at recovering fine and ultra-fine particles due to high G-forces.
  • Knelson: Reliable recovery rates for a wide range of particle sizes, though may not match Falcon in ultra-fine recovery.

Operating Costs

  • Falcon: Higher initial costs but can have lower operating costs due to high efficiency and less frequent maintenance requirements.
  • Knelson: Generally lower initial costs; however, may have higher operating costs due to batch processing and regular maintenance needs.

Ease of Use

  • Falcon: Easier to maintain and clean, making it favorable for operations needing minimal downtime.
  • Knelson: Might require more manual intervention during maintenance.

Applications

Falcon Concentrators

  1. Gold Recovery: Particularly effective for fine gold recovery in both primary and secondary processes.
  2. Mineral Sands: Effective in recovering fine mineral sands such as ilmenite, rutile, and zircon.
  3. Environmental Applications: Used for recovering heavy metals in environmental clean-up projects.

Knelson Concentrators

  1. Gold and Silver Recovery: Ideal for operations focusing on precious metal recovery.
  2. Platinum Group Metals (PGM): Frequently used in extracting PGMs due to proven efficiency.
  3. Base Metals: Suitable for recovering heavy minerals such as lead, zinc, and tin.

Both Falcon and Knelson concentrators offer excellent solutions for mineral recovery, each with its strengths. The Falcon is typically preferred for operations requiring high G-forces and fine particle recovery, while the Knelson is trusted for versatility and consistent performance. Your choice will depend on specific project requirements, budget, and operational preferences.


With a solid understanding of the strengths and applications of each concentrator, mining and mineral processing operators are better equipped to choose the right equipment to maximize recovery and efficiency. Always consider the material characteristics, project scale, and overall cost when making a selection. For detailed consultation, engaging with equipment manufacturers or industry experts can provide additional insights tailored to your needs.
