Laboratory Jigs for Gravity Separation and Mineral Processing
Ünal Engineering designs and manufactures high-quality laboratory jigs for gravity-based mineral separation and process development. Our Single Piston Jig and Three Piston Jig models are built to simulate industrial mineral beneficiation processes on a laboratory scale. These systems allow precise control of pulsation frequency, water flow, and particle feed to achieve reliable and repeatable separation results.
Reliable Gravity Separation Equipment
Gravity separation is one of the oldest and most effective mineral concentration methods. It uses density differences between valuable minerals and gangue materials to achieve separation. Ünal Engineering’s mineral jigs are designed to reproduce these industrial processes in a controlled laboratory environment, providing accurate data for research, quality control, and pilot-scale testing.
Single Piston Jig
The Single Piston Jig is a compact laboratory unit designed for small-scale gravity separation experiments. It uses a single piston to generate pulsating water currents that facilitate the stratification and separation of mineral particles based on specific gravity. The unit allows for easy adjustment of stroke length and frequency, making it suitable for various ore types and laboratory testing conditions.
Features of the Single Piston Jig
- Compact design ideal for laboratory environments
- Adjustable pulsation frequency and stroke control
- Easy sample loading and discharge system
- Durable and corrosion-resistant construction
- Low energy consumption and minimal maintenance
Three Piston Jig
The Three Piston Jig is a larger and more advanced model designed for comparative and multi-sample testing. It operates with three independent pistons, allowing simultaneous separation of different mineral samples under identical or variable test parameters. This configuration is perfect for process optimization and metallurgical research in mining laboratories.
Features of the Three Piston Jig
- Three independent chambers for parallel testing
- Precise control of water pulsation and feed rate
- Robust frame and stainless-steel structure for long-term use
- Transparent sections for visual observation of stratification
- Suitable for heavy mineral and fine particle separation
Applications of Laboratory Jigs
- Ore beneficiation and gravity separation research
- Testing of heavy mineral recovery (tungsten, tin, gold, etc.)
- Density and particle size distribution studies
- Process design and metallurgical optimization
- Educational use in mining and mineral processing courses
Principle of Operation
The laboratory jig works on the principle of differential acceleration and hindered settling of particles in a pulsating water flow. The denser mineral particles sink faster and are collected at the bottom, while lighter materials are carried upward by the water stream. By adjusting water pressure and piston motion, the operator can achieve optimal separation efficiency for different ore types.
Advantages of Ünal Engineering Jigs
- Accurate simulation of industrial jigging conditions
- Customizable design for specific research applications
