Jig concentrators Wikipedia

In the mining of most heavy minerals, the denser material would be the desired mineral and the rest would be discarded as floats (or tailings). There are some minerals, notably coal , that are lighter (lower in density) than the surrounding rock and in such instances the process of extraction would work in reverse, i.e. the coal would settle on top with the rock below (on the jig bed).

Reject with high density concentrates at lower part of jig layer, while clean coal with low density concentrates at higher part. The jig bed moves forward along with horizontal flow, and finally the overflow is clean coal, material discharged on bottom is middlings and reject.

Mineral Jigs for Concentration of Lead Ores

The use of ballmills will diminish the tonnage of jig tailing. The ratio of jig tailing to jig feed may vary from 50 to 80, depending on the means used for crushing the middling. The loss of mineral by jigs, theoretically 4 per cent, but sometimes actually 16 per cent., is three to four times the combined loss of tables and flotation plants.

Jigging is a process of ore concentration carried out in any fluid whose effectiveness depends on differences in specific gravity of granular mineral particles. It consists of separation of the particles into layers of different specific gravities followed by the removal of the separated layers [1].

Mathematical modelling for optimization of mineral

mineral processing world: temperature. Very little mention of it is made in texts dealing with milling or flotation, for example. However, the unique characteristics of temperature, that ˜ it is an indicator of the energy content of the material concerned, and ˜ it can be very easily, cheaply and accurately measured

Working Principles of Jig: Pulsion Suction

Working Principles of jigging are pulsion suction The effect of pulsion depends upon the laws of equalsettling particles, interstitial currents, and, possibly, also of acceleration. The chief function of pulsion is to save the larger grains of the heavier mineral, or the grains which settle faster and farther than the waste.

Gold Jig Mineral Processing Jigs

In the science of mineral processing technique, beneficiation processes (with and without gravity separation) have been extended by investigative research to include compound water cyclones and rotating bowl separators in which centrifugal forces are used to enhance gravity differences, and combined gravity/froth flotation techniques and centrifugal jig separation. An important aim has been to accurately predict the stratification of typically equant heavy mineral particles
