2018-07-17· 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.
Gravity concentration is one of the oldest, well proven solutions used to extract precious minerals from the surrounding material. It is based on the difference in the densities of the gangue materials and that of the target mineral.
