Jigs are the earliest type of process equipments employed in mineral separation but the newly developed under bed pulsated APIC Jig has considerable advantages over its counterparts. This is because under bed air pulsed Jigs are capable of generating the large pulse amplitudes required to fluidise a deep bed of heavy ore particularly Lump Iron ore.
The Paddock pneumatic ore separator is a jig, in which air is used instead of the fluid more commonly employed—water. Like the water jig, it consists of an inclined sieve, over which the crushed ore is passed, and through which the air is blown into the ore. The air current is intermittent, and being proportioned in strength to the thickness ...
The continuous test provides similar pulse characteristics Figures 7 and 8 shows the fit between the calibrated to a large industrial jig, and the pilot jig consumes about 10 ASTRAD model, and real stratification data for different ton/hour of iron ore, fines, smalls and lumpy, then at various residence times in a batch jig (MDS) and an APIC ...
The slag is separated into coarse and fine size fractions with the coarse (-25 +6ram) being treated in a two, stage air pulsed jig. This jig produces directly salable coarse alloy and a middlings fraction for recycle, with recoveries in excess of 95% of liberated metal being achievable. In other plants (-30 +3ram) is jigged in the coarse section.
Stratification studies with Iron ore lump and fines were carried out by using under bed air pulsed jig at optimised parameters as shown in Table 4. The stratification studies were done at 1, 2, 5, 10, 15 and 20 min for both lump and fines. At the end of each residence time pre-determined number of layers was drawn.

The pulse is created by air that enters and exits the air chambers situated underneath the screen deck. The air forces the water in the air chamber down, creating the pulse on the ore bed, and lets the air out to allow the ore bed to settle on the jig screen deck before the next pulse begins. The air is
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)..
