The present invention relates to an electrolytic gold recovery device having adsorption means for promoting the adsorption movement of gold particles so that the gold recovery is made significantly faster and the gold recovery rate is increased.

In general, the gold particles are recovered from the gold plating or gold alloy plating site to be lost in the wash water, and since the gold is expensive, especially the gold is required to maximize the recovery rate and to be recovered quickly. It mainly uses electrolysis method or anion resin adsorption method.

Electrolysis recovery of gold particles combined with citric acid in order to prevent precipitation in the plating solution is carried out by electrotransmitting the gold particles in the citric acid by the electric permeability and attaching the gold particles to the negative electrode plate by using the current flow from the anode to the cathode Recover as much as possible.

However, the electrolysis method has a problem in that the recovery rate is lowered due to the disappearance of hydrogen ions generated over time because gold particles are unstablely attached to the negative electrode plate while being dropped again by the flow of treated water.

In addition, in the case of a technique using anion resin adsorption, the citric acid component is difficult to separate the gold particles when the temperature drops, so in the natural state, the rate of complexation to the anion resin is slow, takes a long recovery time and has a problem of low recovery rate.

The present invention has been devised to solve the above problems,

An object of the present invention is to place gold adsorption means in the path of ionization of gold particles in recovering gold contained in the plating solution wash water by electrolysis method, so that electrolysis and adsorption collection are simultaneously performed. It is to provide an electrolysis gold recovery device having an adsorption means to promote the recovery speed is made remarkably fast to increase the recovery rate.

As shown in Figure 1 and 2, the electrolytic gold recovery device 1 is provided with the adsorption means according to the present invention is a drum in which the gold-containing treated water inlet pipe 11 and the discharge recovery pipe 13 is installed ( 10) In the gold recovery apparatus for extracting gold from the gold-containing treated water by the electrolysis of the positive electrode (+) and the negative electrode (-) electrode plate 30, the inlet pipe (11) to the drum (10) And a positive electrode plate 31 or a negative electrode plate 33 in the form of a filtering net 21 and a porous plate, respectively, on both sides where the recovery pipe 13 is installed, and between the positive electrode plate 31 and the negative electrode plate 33, respectively. Means 40 are mounted, the stirrer 50 is provided with one or more sets of stirring blades 55 on the shaft 53 rotated by the drive device 51 to prevent condensation of the gold adsorption means (40) And, it is provided on the stirrer shaft 53, the brush 61 for cleaning the electrode plate 30 is provided in the drum (10).

Here, the drum 10 is vertically installed, the inlet pipe 11 and the positive electrode plate 31 is installed below, the recovery pipe 13 and the negative electrode plate 33 is installed at the top, the treated water and gold particles are moved upwards, The brush 61 is preferably installed on the positive plate 31 side.

However, as shown in FIG. 3, the inlet pipe 11 and the positive electrode plate 31 are disposed at the upper side, and the recovery tube 13 and the negative electrode plate 33 are disposed at the lower side, so that the treated water and the gold particles are moved downward. It's okay.

As another embodiment 1A of the present invention, as shown in FIG. 4, the positive electrode plate 31 and the negative electrode plate 33 are connected to an electrode switching unit (not shown) controlled by a separate control unit to have a polarity. It is switched at set time intervals, and the stirrer 50 and the brush 61 are separately installed on both electrode plates 30. At the same time, the inlet pipe 11 and the recovery pipe 13 are also controlled to be switched to each other by the valve device 19 to change the flow direction of the treated water in the drum.

At this time, the gold adsorption means 40 is an anion resin (41).

The drum 10 may be installed horizontally as shown in FIG.

As another embodiment (1B) according to the present invention, as shown in Figure 6 and 7, the gold adsorption means 40 is coated by coating the liquid adsorbent material (43b) on a non-magnetic material (43a) The treated gold adsorption bowl 43 may be composed.

Unlike the anion resin 41, the gold adsorption bowl 43 is located under the drum 10 because it is a heavy product, and thus the inflow pipe 11 and the recovery pipe 13 and the electrode plate 30 are treated with water. The gold particles are arranged to move downward.

As another embodiment (1C) according to the present invention, as shown in Figure 8, the drum 10 is connected to the plurality through the connecting pipe 15 is made so that the electrolysis and adsorption is made continuously This can further increase the benefits. The filter net 21 is to prevent the loss of the gold adsorption means 40, the reference numeral '16' is a pump, '17' is a treatment tank, '31a', '33a' is a hole formed in the electrode plate .

Looking at the operation state of the electrolytic gold recovery device (1) having an adsorption means according to the present invention having such a configuration as follows.

Looking at the working state of the present invention with reference to Figure 1, the gold-containing treated water flows into the drum 10 by the pump 16 driving the flow toward the treatment tank 17 at the top of the drum (10) Current flows toward the negative electrode plate 31 disposed above the positive electrode plate 33 provided below.

The gold-containing treated water introduced into the drum 10 is ionized by the gold particles bound to the citric acid by the electric transmission force generated by both electrode plates 30 while passing through the filter net 21 and the positive electrode plate 33. Then, it moves toward the negative electrode plate 31 and is collected in the negative ion resin 41 which is a gold adsorption means mounted on the movement path, and the rest is attached to the negative electrode plate 33.

In addition, since the stirring blade 55 continuously stirs the anion resin 41 while the stirrer 50 is operated, the anion resin is prevented from being entangled, thereby maintaining the surface area where gold particles are adsorbed in the best state, thereby effectively extracting the gold. It keeps things going.

In addition, when foreign matter is attached to the positive electrode plate 31, the electrolytic ionization is weakened, and the brush 61 prevents this. The brush 61 is fixed to the shaft 53 of the stirrer and rotates with the stirring blade 55 to clean the foreign matter attached to the filtering net 21 through the hole 33a formed in the positive electrode plate 33 and the positive electrode plate.
