What are jigging machines?

A Mineral jigging machines is a gravity concentration device that separates particles of different densities by pulsating a water column through a bed of material. This causes denser particles to settle faster and lower, while lighter particles are lifted higher and discharged.

A jig machine, or mineral jig, is a device that separates materials of different densities. The core principle is simple: differences in how fast particles settle in water. Imagine dropping a small stone and a piece of wood into a tube of water; the stone sinks faster. A jig machine does this repeatedly and on a large scale. It uses a pulsating column of water to repeatedly lift a bed of crushed ore. During each pulse, the particles are briefly suspended, allowing the denser (heavier) minerals to sink faster and work their way to the bottom, while the less dense (lighter) waste particles stay near the top. This creates distinct layers, which can then be separated.

Why Use a Jig Machinery for Mineral Processing?

Using a jig machinery in your mineral processing circuit offers significant advantages. 

The primary benefits are its high efficiency, low operating cost, and environmental friendliness. Unlike other methods that require expensive chemical reagents, a gravity separation jig mainly uses water and electricity, keeping your operational costs down. These machines can handle large volumes of material, making them suitable for both small and large-scale operations. They are also relatively simple to operate and maintain.

At ZONEDING, our jig machines are designed for maximum throughput with minimal power consumption, providing you with a highly economical solution for ore concentration.

Applications for Jigging Machine?

The application of a jigging machine is incredibly broad, extending beyond traditional mining. You can use this versatile equipment in many industries. Its ability to effectively separate materials based on density makes it an invaluable tool. Here are some of the most common applications for a jig machine:

• Mineral Concentration: This is the primary use, for concentrating ores like iron, manganese, tin, tungsten, and barite.
• Precious Metal Recovery: It is highly effective for recovering gold and diamonds from alluvial or placer deposits.
• Coal Washing: Jigs are used to separate valuable coal from waste rock like shale and pyrite, improving the coal’s quality and energy value.
• Slag Processing: You can recover valuable metals from industrial slag produced by smelters.
• Recycling: It can be used to separate different types of materials in recycling streams, such as separating heavy metals from shredded plastic.

What Types of Minerals Can a Jigging Separator Process?

A jigging separator is effective for any mineral that has a significant density difference from its associated waste rock (gangue). It is particularly effective for processing heavy minerals. If you can feel a noticeable weight difference between your target mineral and the surrounding rock, a jig will likely work well. The greater the density difference, the easier and more efficient the separation will be. Common minerals successfully processed with our concentrator machine models include:

• Metallic Ores: Iron ore (hematite, magnetite), manganese ore, tin ore (cassiterite), tungsten ore (wolframite), and chrome ore.
• Precious Metals: Placer gold and diamonds.
• Industrial Minerals: Barite, fluorspar, and garnet.
• Fuel: Raw coal for washing and purification.

What are the Structure of a Jigger Separator?

A jigger separator is a robust machine built from several key components, each playing a vital role. Knowing the structure helps you understand its operation and maintenance.

• Jig Box: This is the main body of the machine that holds the water and the mineral bed.
• Screen: A perforated plate or wire mesh at the bottom of the jig box that supports the mineral bed but allows water to pass through. These are high-wear parts, and at ZONEDING, we use highly abrasion-resistant materials to extend their life.
• Drive Mechanism: This is the “heart” of the jig. It generates the pulsating motion. This can be a motor connected to a diaphragm, piston, or an air valve system.
• Hutch: The area below the screen where the densest, fine concentrate collects. A controlled flow of hutch water helps to keep the bed fluidized and assists separation.
• Discharge Gates: Separate outlets for the heavy concentrate and the light tailings to exit the machine.

How Does a Jigging Separator Machine Work?

The operation of a jigging separator machine relies on two key processes: pulsation and stratification. Understanding this helps you see how simple yet effective the machine is.

1. Pulsation: The machine’s drive mechanism creates a repeated upward and downward movement of water through a screen bed. This can be done with a mechanical piston, a flexible diaphragm, or pulsed air. This creates the “jigging” action.
2. Stratification: As your feed material (crushed ore) is introduced onto the screen, the upward pulse of water lifts all the particles. As the water pulse recedes, the particles settle back down. The densest mineral particles sink fastest and deepest into the bed. Lighter waste particles settle more slowly and remain on top.

The mineral ore is continuously fed to the screen plate of the jig chamber to form a thick material layer. Rising water is periodically pumped through the sieve plate to loosen the bed, and then the water flows down (or stops rising). During this process, particles with different densities undergo relative transfer. Heavy minerals enter the lower layer, and light minerals move to the upper layer. After being discharged respectively, the concentrate and tailings are obtained.
