From simple jigs to high G-force gravity centrifuges, knowing which one to use for optimal mineral processing can be complicated and difficult to understand. There are so many factors to consider when creating the ideal circuit; one critical element is the size of the particles you intend to recover.
The fact that treating a mixture of minerals under jigging conditions increased the amount of mineral saved; or, as Professor Richards aptly terms it, " the extra jig-catch," has long been known. To account for this fact a number of theories have been proposed. The work of Rittinger in this field has, for many years, been a cla…
Jig separator (jig concentrator, jig machine) is a equipment that drives pulses of water upwards through a thick bed of settled sediment to keep it loose and agitated.This achieves gravitational separation by allowing the denser minerals to sink easily and quickly through the lighter minerals. Jig separator are widely used in various heavy metal, metallic and …

Mineral processing is an important step in the mining and extraction of raw materials. It involves separating valuable minerals from ore, which is done most efficiently through a process known as jigging. Jigging is a common method of mineral processing and involves the use of a jig, which is a type of mechanical device.
For more than 500 years jigs have been in use for mineral separation. Georgius Agricola first described the application of jigs in the De re metallica in 1550 (a book cataloguing the state of the art of mining, refining, and smelting metals).These jigs were used in land mining and processing applications.
