Main equipment of resin in pulp process
Resin in pulp process equipment of non-standard equipment, almost all major with Mr Qiu card cyanide leaching tank, the high card column adsorption tank, regeneration, electrolytic cell, elevated tank, storage tank, the gold leaching solution preparation tank, solution and pulp distributor, pump, pipeline and air lifter, etc., adsorption - regeneration operation is one of the characteristics of the material by compressed air agitation and transmission, it can reduce the wear and tear of exchange resin, is good for process automation and control.
Its structure is shown in FIG. 5-42. High pressure air is used to achieve mixing of slurry, and the mixing intensity of slurry can be controlled by adjusting pressure and flow of high pressure air.Of the specifications of the cyanide bath are often ¢3.7 ×13.7m, ¢7.6×16.8 m， ¢6.8 x 13.7 m, 10.1 x 13.7 m , etc.
2. Pachuca adsorption tank
Its structure as shown in figure 5-43, tank with pulp circulator and air lifter, for in cyanide pulp after molten gold exchange resin adsorption of them by air lifter transmit pulp with resin to pulp buffers, borrow rebound deflection plate to make pulp of downstream to the distributor, the distributor at the bottom of the aperture and chute will pulp import slope is 3 ° inclined sifting, make pulp and exchange resin separation.The slurry smaller than 0.2mm flows back to the adsorption tank through a screen mesh and enters the regeneration column after being cleaned with gold resin.After carrying the gold resin, as with the carbon in puip process, it is necessary to carry the resin through the grooves, and add the new resin or the regenera
3. Air hoist
The structure of the intermediate air hoist used for transport of solution or slurry between devices is shown in FIG. 5-45.Compared with the centrifugal pump, the air hoist is reliable, easy to operate and has less wear on the exchange resin.During operation, the solution or slurry and compressed air enter the overflow cup to form a mixture of liquid and gas.Due to its low density, the liquid-gas mixture rises along the central air riser to the gas-liquid separator under the pressure of the liquid column or slurry column.Excess air is discharged through the exhaust pipe, and the solution or slurry flows through the overflow pipe to the next tank (column).
4. Solution separator
When air lifts the resin, it must be transported with the solution, thus bringing the solution of the previous process into the next process, resulting in the mixing of different solutions or dilution of the solution in different processes, resulting in increased gold leaching agent consumption.A solution separator can be used to separate the resin from the solution in order to reduce the consumption of the impregant and ensure the normal operation.The separation of the resin in the lifting fluid in each process of regeneration is carried out directly on the screen surface of the separator. The screen surface area depends on the ability of the regeneration column to treat the resin, generally 0.1-0.4m 2.When used in aggressive media, the solution separator should be made of titanium alloy.
