Jig Machine for Coarse Gold, Tin, Manganese & Diamond Recovery
What is a Jig Machine?
A jig machine (also called a mineral jig concentrator) is a highly efficient gravity separation device that separates valuable minerals from gangue based on differences in specific gravity. First of all, it is widely recognized for its ability to handle a wide range of particle sizes and achieve high separation efficiency with minimal energy consumption. Unlike other gravity equipment, the jig machine uses a pulsating water flow to stratify materials: heavy minerals sink to the bottom through a screen bed, while lighter gangue is carried over the bed and discharged as tailings. Therefore, it is one of the most versatile and cost-effective solutions for coarse and medium-sized mineral recovery.

Wide Applications of Our Jig Machine
Our jig machine is a versatile solution widely used for various coarse-grained minerals:
Coarse Gold Recovery: Highly effective for recovering coarse gold particles and nuggets from placer and alluvial deposits.
Tin & Tungsten Mining: Efficiently separates heavy tin and tungsten minerals from lighter gangue.
Manganese Ore Beneficiation: Upgrades manganese ore by effectively removing lighter impurities and waste rock.
Diamond & Gemstone Recovery: The gentle pulsating action prevents damage to fragile crystals, making it ideal for diamond recovery.
Barite Processing: Effectively separates high-specific-gravity barite from associated gangue minerals.
Coal Cleaning: Separates coal from associated waste rock, improving quality and calorific value.

Frequently Asked Questions
Q: What is the difference between a jig machine and a shaking table?
A: A jig machine handles larger feed sizes and higher capacities, making it ideal for coarse roughing. A shaking table is better for fine particle separation and final concentrate upgrading.
Q: What is the minimum particle size a jig machine can recover?
A: Jig machines are most effective for particles larger than 0.5mm. For finer gold, a centrifugal concentrator or shaking table is recommended.
Q: How often should I clean the jig concentrate?
A: The cleaning cycle depends on ore grade. For vein gold, typically every 1-4 hours. For placer gold, every 2-6 hours.
Q: Does the jig machine require chemicals?
A: No. The jig machine uses only water and gravity. It is a completely physical separation process with zero chemical pollution.
