First, the sieve The ГПС-42 type sieve was used for sieving and removing wood chips from the slurry and the missing resin was collected. The sieves of the saturated resin were sieved with ГВ-06 and Г-2, and their technical characteristics are listed in Table 1. Recently, the rotary screen has been widely used in the adsorption process because it works more smoothly than the flat vibrating screen and does not cause vibration of the gold filing structure and equipment on the screen. In order to operate the sieve properly, a cover is placed in the sieve feeding zone to protect the screen surface and prevent the slurry from splashing.

In the Soviet Union, МОД-1 and МОД-2 type jigs were used to separate ore from saturated resin. Their technical characteristics are listed in Table 2. In order to obtain a good separation effect, the jig needs to pass the test to select the diaphragm stroke and the number of pulses, the thickness of the artificial bed and adjust the water supply under the sieve tray. Since the density and particle size of the jigging material are virtually constant (processing the same raw material), the separation process depends on the thickness of the artificial bed and the amount of water supplied under the sieve tray after the diaphragm stroke and stroke are selected. At this time, special attention should be paid to controlling the amount of water supplied. Insufficient water will cause the resin to fall into the ore. The excess amount of ore will enter the wash column along with the resin. In the process, the jigging feed should be evenly distributed, and the frequent suspension of the feed will destroy the jigging state and deteriorate the separation effect.

The flat bottom tank sludge is easy to accumulate and is inconvenient to remove. The bottom of the arc or the bottom of the cone, the sludge will not stay on the inclined wall at the bottom of the tank, and a new liquid can be added to the discharge pipe without having to be cleaned by manpower. Fourth, the air lifter The structure of the intermediate air lifter used for solution or slurry transport between the various devices is shown in Figure 1. This air lifter is more reliable and easier to operate than a centrifugal pump. Figure 1 Intermediate air lifter 1-overflow cup; 2-feeding pipe; 3-air riser; 4-separator; 5- baffle; 6-exhaust pipe; 7-overflow pipe; 8-accumulation overflow pipe After the solution or slurry enters the overflow cup, compressed air is also supplied to form a liquid-gas mixture which rises along the central air riser into the separator. At this time, excess air is discharged through the exhaust pipe, and the solution is self-flowed into another device through the overflow pipe. Five, solution separator The resin used to transport the resin with the air lifter must be transported together with the solution. In this way, during the regeneration process, the solution of the previous process is brought into the next process, which causes different solutions of different processes to be mixed, thereby increasing the consumption of the agent required for neutralization; or diluting the solution to increase the consumption of the agent. In order not to increase the consumption of the agent and to ensure the normal operation process, a resin solution separator is used. The separation of the resin in the lift liquid in each step of the regeneration is carried out directly on the sieve surface of the separator. The size of the sieve area depends on the ability of the regenerated column to treat the resin, and generally varies within a range of 0.1 to 0.4 m 2 . When used to separate resin from aggressive media, the separator is fabricated using a milling alloy.
