Description

Application area

Non-ferrous metallurgy and the extraction of alluvial diamonds and other solid heavy minerals from the pulp of hydro-washing devices in deep filling locks of the elevator type.

The purpose of the invention

Increase in labor productivity in non-ferrous metallurgy by increasing the completeness of the recovered gold and platinum from the pulp of industrial hydromolting devices.

State of the art

Elevator-type deep filling gateway with rubber mats at its bottom covered with stencils. This gateway has the following disadvantages:

1. Only the bottom surface of the sluice, represented by rubber mats that are covered with stencils, affects the pulp particles.

2. The deposition area of gold, platinum is very small.

3. There is no effect on the liquid and solid parts of the pulp throughout its thickness.

4. The number of applied physical forces is not enough for a more complete extraction of gold, platinum.

The combination of the above factors leads to significant operational losses of gold particles, platinum with a size of less than 4 mm. The smaller the particle size, the higher the percentage of loss. At the submillimeter level, the percentage of losses can reach up to 90%.

SUMMARY OF THE INVENTION

1. Information disclosing the essence of the invention.

The objective of the present invention is the creation of a device with which it would be possible to maximally extract gold millimeter and submillimeter sizes from the pulp of industrial hydraulic washing devices in deep filling floodgates of the elevator type.

The place where the device is to be installed is determined - this is the sedimentary gateway of industrial hydraulic washing devices.

According to the conditions of the technological process, the device must be replaced with a spare for a short time interval equal to ten to twenty minutes. The removed device is cleaned of soil and concentrate, prepared for work, and then re-installed in the gateway. This cycle continues many times.

It is determined that the above conditions correspond to a device consisting of individual segments.

Each device segment performs a specific task. All assembled device segments perform a common task. Segments differ from each other in terms of configuration with structural elements.

The technical result is achieved by passing the pulp through a set of nets, stencils having linear holes of various sizes, located above a layer of material having a low specific gravity, such as charcoal, polystyrene and the like. The pulp of industrial water-washing devices consists of a liquid part, i.e. water, and solid particles, including gold (platinum), having various linear sizes in the range from 0 to 20 mm. The ratio of liquid to solid parts of the pulp is preferably in excess of 20: 1.

Grids, stencils are located above the bottom of the gateway, which is covered with a material having a low specific gravity. The layer height of this material decreases stepwise from the beginning of the device to its end.

The height of the layer with a low specific gravity at the beginning of the device is equal to the height of the pulp layer. At the end of the device, the height of this layer can be four times less. The number of grids, stencils is increasing from the beginning to the end of the device. At the beginning of the device there is one stencil, one grid, and the material with a low specific gravity is in the maximum quantity. In the last segments of the device there are five stencils and four grids and a minimum amount of material with a low specific gravity. Stencils, grids form single lines passing inside the pulp layer parallel to the bottom of the gateway, with these lines the pulp stream is conditionally divided into several layers in which the processes occur:

1. Classification of pulp solids by narrow linear interval values.

2. The deposition of gold (platinum) on stencils, grids under the influence of gravitational forces.

3. The capture of the smallest particles of gold on a material with a low specific gravity.

For the above processes in the device creates optimal conditions.

Component parts of the device

A device “U”, consisting of eight sections: I, II, III, IV, etc., each of which has two segments FGHIKLMN, is introduced into the 18 meter elevator-type sedimentary lock. Arabic numerals 1, 2 indicate the segment number in the section. Then the segment numbering will look like I-1, I-2, II-1, II-2, III-1, III-2, etc. Segments are arranged one after another in accordance with the numbering.

The segment made of metal corners has the shape of a hollow parallelepiped, in which FGHI is the upper base and KLMN is the lower base. At the vertices of the parallelepiped, the corners are rigidly interconnected by a weld. O-plates with holes are welded to the upper FGHI base with which the device can be inserted into the gateway and retracted by a crane as needed. In the corners of the lower base KLMN of the FGHIKLMN segment, round metal rods “P” are installed by means of a weld, which extend vertically upward from the lower base to the upper base FGHI and serve to “string” sets “T” consisting of frames for nets, nets and stencils which segments are populated with. At the corners of the frames of grids and stencils, plates “R” are welded, having round holes for stringing onto the rod-rods “R”. To regulate the distance between the frames of the nets and stencils, metal hollow cylinders-sleeves “S” are put on the rod rods “P”. The height of the bushings makes it possible to change the location of the lines of stencils and grids with respect to the bottom line of the lock: a) parallel arrangement, b) adjust the inclination of the entire line of sets, c) adjust the inclination of individual sections of the line of sets “T”.

A material with a low specific gravity 1 is installed on the lower base of the FGHIKLMN segment. It can be charcoal or foam, covered with a bottom stencil 2, on which the smallest particles of gold and platinum are deposited. The bottom stencil 2 has “R” plates at the corners, with the help of which the stencils are strung on a metal rod “P”. Then, cylinder sleeves “S” are put on the rod “P”. Then, a frame 3 is put on the rod “P”, in which a grid 4 is enclosed with a linear hole size of 0.5 mm. A template 5 is put on top of the “P” rod. All the above elements are present in all segments in various combinations.

Frame 3, mesh 4, stencil 5 form a set of "T". Several such sets, separated by spaces of at least 40 mm by “S” cylinder sleeves, installed along the length of the airlock and parallel to the bottom or at an angle, divide the pulp conditionally into layers. There may be several such layers. The height of the material with a low specific gravity of 1 decreases stepwise towards the end of the lock. At the same time, the number of “T” sets, consisting of a frame, mesh, stencil, increases towards the end of the gateway. Linear openings of grids and stencils in the “T” set increase from a minimum value of 0.5 mm in the “T-1” set located above the stencil-2 to a maximum value of 4 mm in the “T-4” set.

Device operation

The pulp of an industrial hydraulic washing device enters the AVSD gateway. The pulp contains solid particles having linear dimensions from twenty millimeters to several microns.

The pulp enters the beginning of the device "U", in the first segment of the device, having the numbering I-1. The pulp height is such that the upper layers of the pulp move above the upper stencils of the segments of the device "U". The pulp moves along the lock, going down the steps of the layer with a low specific gravity in the segments of the sections. In this case, solid particles, trying to descend into the lower layers of the pulp under the action of gravity, meet an obstacle in the form of nets and stencils. The nets and stencils have openings of certain linear dimensions, which decrease as you approach the lower layers of the pulp. First, the pulp passes through a stencil 14 having a linear hole size of 4 mm. Solid particles having dimensions less than 4 mm pass through the stencil, particles larger than 4 mm roll on the stencil 14, carried away by the liquid part of the pulp. Gold particles with a linear size of more than 4 mm have a mass of more than 1200 mg, and solid pulp particles with a linear size of less than 20 mm have a mass of less than 1200 mg. Liquid pulp moves lighter gravel particles, and gold settles on the stencil.

The pulp passing through the stencil 14 descends “stepwise” from the I-1 segment to the I-2 segment and encounters a mesh 13 enclosed in the frame 12. On its way, the mesh 13 has an opening with a linear size of 3.2 mm. Solid pulp particles passing through the stencil 14 and having a size of less than 4 mm but greater than 3.2 mm will not pass through the grid and will move the liquid part of the pulp along the grid 13 to the end of the device. Sand particles with a linear size of 4 mm have a maximum mass of 200 mg, and gold particles with a linear size of 3.2 mm have a mass of more than 500 mg. The speed of the upper layers of the pulp is much higher than the speed of the lower layers of the pulp, this speed will be enough to wash off the lighter particles of sand, but not enough to wash off the particles of gold.

In addition to the speed of movement of the pulp, the friction force of the gold particles on the grid is important, which also prevents the washing off of the gold particles outside the device for a certain period of time, which the gold particle needs to overcome the entire path, and this is over 18 meters, i.e. the length of the gateway and, accordingly, the device "U".

So, the pulp moves further along the device, passes from segment I-2 to segment II-1. Already in segment I-2, the pulp passes through a stencil 11 having a hole size of 2.5 mm, where processes similar to those described above occur: pulp solid particles are classified into narrow linear intervals and gold particles are deposited on grids and stencils.

Moving from segment to device segment "U", the pulp, which has in its composition the smallest gold particles with a linear size of less than 0.5 mm, reaches segment III-1. From this segment onwards in all segments III-1; III-2; IV-1; IV-2 in the bottom layer of the pulp begins the deposition process on a material with a low specific gravity of 1 minute gold particles.

Pulp leaves segment IV-2 in the external environment. The operation of the device "U" is over. The process of extracting gold from the pulp is over.

Thus, there is a process of separation of pulp solids into certain groups, limited to linear intervals. This process is called classification. The speed of the pulp, namely its upper layers, is greater than the speed of the pulp in the lower layers. Accordingly, the pulp of the upper layers can move more massive solid pulp particles, while the more massive solid pulp particles move each other. When solid particles with the dimensions of a given linear interval are grouped, the gold particles among them, as more massive, do not move with the surrounding particles, and conditions arise for their deposition on grids and stencils.

The proposed mechanism was not proposed and not considered at the level of millimeter and submillimeter linear dimensions.

In operation of the device represented particulate classification processes pulp at millimeter and sub-millimeter linear dimensions and gravitational deposition on grids, stencils and bottom material of a low specific gravity less than 0.8 g / cm ^3. Given all of the above, the degree of gold extraction from the pulp of industrial hydroflushing devices in the sedimentary lock of the elevator type increases sharply compared to the work of sedimentary locks equipped with rubber mats that are covered with stencils. Gold operational losses at millimeter and submillimeter sizes are also sharply reduced.

The form of the execution of the elements of the device

Since the device "U" is installed in the gateway, it repeats the form of this gateway AVSD. Geometrically, the device is made in the form of a parallelepiped, in which the height is much less than the base. Each of the FGHIKLMN segments also has a parallelepiped shape, in which the ratio of height to base is already not so great.
