Description

The claimed utility model relates to inorganic chemistry and can be used at enterprises that process technogenic raw materials with different contents of the target components.

A device is known (RU 2119541 C1, IPC B01D 21/00, C01G 3/00, (St. Petersburg branch of NPF Bashkir Gold Mining Company) September 27, 1998), which relates to the extraction of precious metals from intermediates, and includes a furnace bath, which consists of two parts - the upper and lower. The lower part of the furnace bath is located in the cone-shaped part of the lined casing and is equipped with an outlet at the bottom of the cone. The upper part of the furnace bath is located in the cylindrical part of the casing and is equipped with an outlet at the level of transition of the cylinder into the cone.

The technical result of the claimed technical solution is to improve the quality of leaching, which means: reducing the leaching time while increasing the extraction of the target components with a decrease in the number of utilized solutions.

The technical result is achieved by a new structural embodiment of the device for the extraction of useful components, which is a bath consisting of two parts, the upper rectangular and lower conical, with a perforated drum placed inside it on the drive shaft, equipped with a hermetically sealed lid with a mesh size less than the minimum grain size of the processed raw materials, at the bottom of the bath mounted pipe for draining the leach solution and a shutter for unloading insoluble residue.

It should be noted the particular importance of the signs that a drive shaft is mounted inside the bathtub on which a perforated drum is placed, with a mesh size smaller than the minimum grain size of the processed raw materials. The drum is equipped with a hermetically sealed lid with a shutter for unloading leach products and a nozzle for draining leach solutions. The device also has a steam supply coil for heating the contents of the bath and a thermocouple for temperature control.

The device shown in the drawing, which shows:

1 - bath

2 - shutter

3 - drain pipe

4 - coil

5 - drive shaft

6 - gear motor

7 - perforated drum with a cover

8 - bath cover

9 - thermocouple.

The device operates as follows. The raw materials are loaded into the drum through an opening, which is closed with a lid with fixed clamps. The bath is filled with a leach solution to a level below the level of the drive shaft by 50-100 mm. Using a gear motor, the rotation of the drum is started, and with the help of a coil, the contents of the bath are heated. As it dissolves, the leach product through the cells of the perforated drum enters the bath and lays on its bottom. After leaching is complete, the clarified part of the solution is discharged through a drain pipe to a suction filter, filtered and sent for disposal. The insoluble residue containing the recovered useful components is discharged through the shutter to a suction filter and filtered.

Thus, with the optimal ratio of the amount of processed raw materials to the volume of the leach solution, the maximum possible concentration of the target component in the insoluble residue and the minimum residual content of the target component in the leach solution are ensured.
