The closest in essence and the technical result achieved is the device for extracting useful components, known from patent RU 180009 U1, 05/30/2018, B01D 21/00, which is a bath with a lid, consisting of two parts, an 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, a drain pipe is mounted at the bottom of the bath to drain the solution into schelachivaniya and the shutter for the discharge of the insoluble residue. Moreover, the device has a steam supply coil for heating the contents of the bath and a thermocouple for temperature control.

Utility Model Disclosure

The technical problem, the solution of which is directed by the present utility model, is the expansion of the functionality of the claimed device.

This problem is solved due to the fact that the device for extracting useful components, according to the utility model, is a bath with a lid, consisting of two parts, a rectangular top and a lower cone-shaped, with a perforated drum placed inside it on the drive shaft and equipped with a hermetically sealed lid with a mesh size smaller than the minimum grain size of the processed raw materials, a drain pipe is mounted at the bottom of the bath for draining the leach solution and a shutter for unloading insoluble waste Atka, wherein the apparatus is further provided with hlorprovodom for saturating the leach solution and chlorine gas duct for stirring the bath contents.

The technical result of this utility model, in comparison with the closest analogue, consists in better mixing of the processed raw materials while ensuring the minimum concentration of the target component in the insoluble residue and the maximum content of the target component in the leach solution.

Brief Description of the Drawings

The utility model is illustrated in the drawing, which shows a General view of the claimed device.

Utility Model Implementation

The device for extracting useful components is a vertically mounted bath 1, consisting of two parts: the upper rectangular one, equipped with a lid 8 with flanges, and the lower cone-shaped. Inside the bath 1, a drive shaft 5 is mounted on which a perforated drum 7 is placed, with a mesh size smaller than the minimum grain size of the processed raw materials. The drum 7 is equipped with a hermetically sealed lid. A shutter 2 is installed in the bottom of the bath 1 for unloading the leachate products and a nozzle 3 is placed for draining the leach solutions.

Inside the bath are installed:

- coil 4 steam supply, to ensure heating of the contents of the bath;

- thermocouple 9 to provide temperature control;

- chlorine pipeline 10 to saturate the solution of leaching with chlorine;

- air duct 11 for mixing the contents of the bath.

The raw materials are loaded into the drum 7 through the hole, which is closed with a lid with fixed clamps. The bath 1 is filled with a leach solution to a level below the placement level of the drive shaft 5 by 50-100 mm Using a gear motor 6, the rotation of the drum 7 is started, and using the coil 4, the contents of the bath 1 are heated.

Air is passed through the air duct 11 to the bath 1 to ensure high-quality mixing of the contents of the bath 1, and gaseous chlorine, which in the leaching solution acts on the material to be processed, is mixed through the chlorine duct 10.

As it dissolves, the leach product through the cells of the perforated drum enters the bath 1 and lies on its bottom. After leaching is complete, the clarified part of the solution through the drain pipe 3 is discharged to a suction filter (not shown in the drawing), filtered and sent to extract useful components. The insoluble residue is discharged through the shutter to a suction filter and filtered.

The raw material for leaching the raw material is a granular alloy containing precious metals and impurity metals, in particular iron.

a) When processing raw materials using the device described in patent RU 180009, without the use of chlorine gas, a minimum concentration of the target component (gold) in the leach solution and a maximum concentration of the target component (gold) in the insoluble residue are ensured:

This dissolution technology is used in the presence of iron and other base impurities in the feed (more than 50%).

b) When processing raw materials using the device described in this application using chlorine gas, the maximum concentration of the target component in the leach solution (gold) and the minimum concentration of the target component (gold) in the insoluble residue are ensured:

This dissolution technology is used when iron and other base impurities are present in the feed (less than 50%).

Thus, by passing air and chlorine through the leach solution, a minimum concentration of the target component in the insoluble residue and a maximum content of the target component in the leach solution are ensured.
