Concentrators are machines used to separate gold particles from other materials, such as rock, sand, or ore. They rely on differences in physical properties, such as density or particle size, to concentrate gold, which is denser than most other materials in the ore. Concentrators are essential in gold recovery, especially in small-scale and artisanal mining, as well as in large-scale operations.
Types of Concentrators in Gold Mining:
- Centrifugal Concentrators:
- Use centrifugal force to separate gold from other materials.
- Common examples: Knelson Concentrator and Falcon Concentrator.
- Effective for fine gold recovery from ores, tailings, or alluvial deposits.
- Shaking Tables:
- Use a combination of mechanical vibration and water flow to separate gold.
- Ideal for separating gold from heavy minerals after initial processing.
- Jigs:
- Utilize a pulsating water flow to create a stratified layer of materials.
- Heavier gold particles settle at the bottom, while lighter materials are washed away.
- Spiral Concentrators:
- Consist of a helical channel where slurry flows downward.
- Gravity and centrifugal forces concentrate heavier gold particles.
- Sluice Boxes:
- Simple devices that use water flow to trap gold in riffles or mats.
- Commonly used by artisanal miners for alluvial gold recovery.
- Flotation Cells:
- Use chemicals and air bubbles to separate gold from sulfide ores.
- Effective for recovering gold in complex ores with sulfide minerals.
Key Features of Concentrators:
- They improve gold recovery rates by concentrating the metal in a smaller volume.
- Help minimize the amount of material sent to further processing stages.
- Reduce operational costs by efficiently isolating gold from waste material.
Concentrators are selected based on the type of deposit, the size of the operation, and the particle size of the gold being recovered.
