Sep 25, 2018·Jigging processis anore concentration processwhich is carried out in any fluid whose effectiveness depends on differences in the density of the granular mineral particles. It consists of separation of the particles into layers of different specific gravities followed by the removal of the separated layers.

Ore is a deposit in the Earths crust of one or more valuable minerals. The most valuable ore deposits contain metals crucial to industry and trade, like copper, gold, and iron. Copper ore is mined for a variety of industrial uses. Copper, an excellent conductor of electricity, is used as electrical wire.
