Jiggers play a crucial role in gold mining, especially for gravity-based separation. How do these machines help extract gold efficiently?In gold mining, gravity separation is key to recovering valuable metals. The jigger, a powerful tool in modern mining, has become essential for this process.In this post, you’ll learn how jiggers work, their benefits, and why they are so important in the mining industry.
A jigger machine is a gravity-based separation tool used in gold mining to extract precious metals. It is designed to sort materials by their density, a crucial step in recovering gold from ore. The jigger’s ability to separate heavier materials, like gold, from lighter ones makes it invaluable in the mining process.
The jigger has been used for decades in the mining industry. Over time, its design has evolved to improve efficiency, allowing it to handle different types of gold-bearing materials. Today, jiggers are essential tools for both small and large-scale mining operations.
The principle behind a jigger is simple but effective: it uses water and pulsation to separate materials based on their density. The denser gold particles settle faster, while lighter materials remain at the top. This method is efficient, cost-effective, and environmentally friendly.
A jigger works by creating a vertical movement in water, which causes the heavier particles to sink while the lighter ones stay on top. This process, called gravity separation, is enhanced by water flow and pulsation, which create layers of different densities.
The water moves through the jigger’s bed, agitating the material. Heavier particles, like gold, settle at the bottom because they are denser, while lighter materials, like sand or dirt, rise to the top. This allows the gold to be separated efficiently.
Jiggers are crucial for recovering gold, especially coarse particles and nuggets. The machine’s ability to separate these heavy particles from lighter materials makes it ideal for gold recovery. After the gold is separated, it is collected and processed further.
In gold mining, the jigger is one of the most effective ways to recover gold from ore. It ensures that even the smallest gold nuggets are not lost in the process. This makes the jigger an essential piece of equipment in modern mining operations.
Qingdao Relong Technology Co., Ltd is known for manufacturing high-quality gold mining equipment, including jiggers, which are vital in improving gold recovery in various mining environments.

The jigging chamber is a critical component in a jigger machine. It is where the separation of gold from other materials takes place. The size and configuration of the jigging chamber determine how effectively the machine can handle different types of gold-bearing materials.
Chamber size: Larger chambers allow for processing more material, while smaller chambers are more efficient for fine gold recovery.
Stroke length: The length of the stroke, or the up-and-down movement, plays a significant role in how efficiently the machine separates the gold. A longer stroke can help separate larger particles, while a shorter stroke may be better for fine gold.
A well-designed jigging chamber and proper stroke settings lead to higher gold recovery rates.
Water pressure and flow rate are crucial in ensuring optimal gold separation. The water moves through the jigging chamber, creating the necessary pulsation to separate the gold from other materials.
Water pressure: Adjusting water pressure is essential for controlling the speed of particle movement. Too much pressure can cause gold to be lost, while too little can result in inefficient separation.
Flow rate: The water flow rate affects the movement of particles in the chamber. A higher flow rate helps move lighter materials faster, while a lower flow rate ensures that heavier particles, like gold, settle at the bottom.
Proper water pressure and flow rate settings maximize gold recovery efficiency.
