Jigger belongs to the gravity separation equipment, using water as the beneficiation medium, using the specific gravity difference between the selected minerals and the vein to carry out the separation, the feed size is 6-8mm, but in individual cases of selecting alluvial ore, the size can reach 12mm. 

Jigger mostly belongs to the diaphragm type, the stroke and stroke times can be flexibly adjusted according to the specific gravity of the selected minerals, and is widely used in the re-election process of tungsten, tin, alluvial gold, hematite, brown iron, manganese, titanium, antimony, lead, tantalum, niobium and other metals.

Modern jig machines are more often used in the field of mineral processing, and their effectiveness has been greatly improved. The sawtooth wave jigger, for example, is easier to sort because its jigging pulsation takes on a sawtooth shape, making the rising water flow faster than the falling water flow, thus making it easier to precipitate heavy minerals.

The jigger does not require a complicated installation process, is easy to transport, easy to operate, consumes less water than traditional jigging machines, is easier to maintain, and is able to reduce power consumption by more than 70%, i.e., consumes less energy. Because of its wide range of beneficiation and separation size, it is widely used in various mineral processing fields.

The working principle of a jigger may seem complicated, but it is actually very simple. Simply put, a jigger uses the difference in specific gravity of minerals to perform sorting. When the minerals enter the jigging chamber, the water flows upwards to impact the minerals. Due to the different specific gravity of the minerals, they react differently. The heavier minerals will sink, while the lighter minerals will float to the lower layers. This is the sorting process of the jigger.
