Jig Batteries
a) Primary units of jigs. It consists in two Yuba-type cells; they effectuate a gravimetric classification within a semi-stationary bed, with a percentage of 25% of solids and 75% of liquids.
By effect of pulsing and suction that a membrane or diaphragm performs through an embolus actioned by a motor (the same principle of function for the secondary and third jig).
The function of the primary jig is to separate the light material from the heavy material (declaim and eliminates gangas) by a process of sedimentation in a watery medium or pulp according to the specific weights or densities.
b) Secondary units of jigs. It consists in two Denver type cells; it works on gravimetric classification within a semi-stationary bed, with percentages of solids and liquids to the 50% respectively.
It receives the heavy materials treated in the primary jigs in base of concentrate.
c) Tertiary units of jigs. The function and principle of the tertiary jigs are essentially the same as in the primary and secondary jigs.
It effectuates on gravimetric concentration works in final phases; the pulp has a 75% of solids and 25% of liquids.
d) Work regime of the jigs. The cyclical operations of pulsing and suction facilitates for the heavy particles to filter in interstitial spaces, incorporating the heavy ones and eliminating the light ones.
