Working Principle of Jig Separator

Working Principle of Jig Separator The introduction of Jig separator. Jig separator, also known as jig machine, jig concentrator, mineral jig, is a compact and efficient gravity device which is widely used for beneficiaiton of a wide range of minerals. it can separate heavy liberated minerals from light minerals, works on the difference in density.

Jig concentrators - Wikipedia

Jig concentrators are devices used mainly in the mining industry for mineral processing, to separate particles within the ore body, based on their specific gravity (relative density). The particles would usually be of a similar size, often crushed and screened prior to being fed over the jig bed. There are many variations in design; however the basic principles are constant: The particles are introduced to the jig bed (usually a screen) where they are thrust upward by a pulsing water column or

Gravity concentration - Webs

Gravity methods of separation are used to treat a great variety of materials, ranging from heavy metal sulphides such as galena (sp. gr. 7.5) to coal (sp. gr. 1.3), at particle sizes in some cases below 50 txm. These methods declined in importance in the first half of the twentieth century due to the develop-

Application of Jig Separation for Pre-Concentration of Low ...

Jig separation, one of the oldest methods of gravity separation, is commonly used to reduce the costs of subsequent processes by pre-concentrating the valuable minerals from the product following coarse particle crushing. In this study, jig separation was used to pre-concentrate scheelite prior to grinding for the next process.

Gravity Concentration By Jigs Engineering Essay

The jig is normally used to concentrate relatively coarse material. Good separation is possible if the feed is closely sized (e.g. 3 – 10) and if the sp. gr. difference is large. Many large jig circuits are still operated in the coal, cassiteriite, tungsten, gold, barytes and iron-ore industries.
