A gold recovery equipment refers to machinery and tools designed to extract gold from various sources, such as ore, placer deposits, electronic waste (e-waste), or mining tailings. These devices utilize different physical and chemical processes to separate gold from other materials efficiently.
Common Types of Gold Recovery Equipment:
1. Gold Pan – A simple, manual tool used in placer mining to separate gold flakes and nuggets from sediment using water agitation.
2. Slurry Pumps – Used to transport ore slurry in large-scale mining operations.
3. Centrifugal Concentrators (e.g., Knelson, Falcon Concentrators) – High-speed spinning bowls that use centrifugal force to separate heavier gold particles from lighter materials.
4. Shaker Tables – Vibrating tables that separate fine gold particles based on density differences.
5. Jig Machines – Pulsating water flow traps dense gold particles while lighter materials wash away.
6. Spiral Wheels & Blue Bowls – Water-based concentrators that help recover fine gold from black sands.
7. Mercury Amalgamation Equipment (now discouraged due to toxicity) – Used historically but replaced by safer methods.
8. Cyanidation Tanks & Leaching Systems – Chemical processes dissolve gold from crushed ore (common in industrial mining).
9. Electrowinning & Carbon-in-Pulp (CIP) Systems – Extract dissolved gold from cyanide solutions onto cathodes or activated carbon.
10. Metal Detectors & Electronic Scanners – Help locate gold nuggets in placer deposits or e-waste recycling.

Applications:
– Small-scale prospecting (pans, sluice boxes)
– Large-scale industrial mining (heap leaching, CIP plants)
– E-waste recycling (gold recovery from circuit boards)
– Artisanal and hard rock mining
Key Features:
– High recovery rates (>90% efficiency in advanced systems)
– Adjustable settings for different ore types
– Environmentally friendly alternatives replacing mercury/cyanide
– Portable designs for field use
