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
