Description

ELECTROANALYSIS GOLD RECOVERY APPARATUS WITH CATHODE FILLER}

The present invention prevents the loss of the charge by electrolysis in the drum, and the negative electrode member is filled with a negative electrode filler consisting of a bowl, etc. in the negative electrode network, thereby dramatically improving the surface area and the gold recovery performance of the negative electrode to which gold particles are adsorbed The present invention relates to an electrolysis gold collecting device having a negative electrode filler.

In general, gold particles contained in plating wash water or plating solutions are recovered from gold plating using industrial gold or printed circuit board manufacturing sites. Such gold is expensive, and thus, the recovery rate is prevented by maximizing recovery rate. In addition, higher recovery performance is required.

For the recovery of gold contained in the gold-containing treated water such as plating wash water, electrolysis or anion resin adsorption is mainly used.

Gold particles are combined with citric acid, an organic substance that is added to the plating solution to prevent sedimentation during the plating process.The electrolysis method uses an electric transmission force to ionize the gold particles in the citric acid and use the current flow from the anode to the cathode. To recover the gold particles to precipitate in the negative electrode plate.

The electrolytic gold retrieval device of the prior art is provided so that the gold-containing treated water passes between the positive plate and the negative plate, which are flat plates, in a passage having an open top.

In this configuration, since the negative electrode member in which the gold particles are precipitated becomes a flat plate, the area where the gold particles are precipitated is very limited, so the gold collection performance is insufficient, and the precipitated gold particles are dropped out again due to the flow rate. Since the particles remain, valuable resources are lost, and some of the charges are swept away by the flow rate, which lowers the electrolysis efficiency and has a low yield rate.

However, in the prior art, the positive electrode plate and the negative electrode plate are fixedly installed only at both ends of the drum, and the gold adsorption means has no electrode, thereby limiting the gold recovery performance.

On the other hand, the anion resin adsorption method is configured to move the plating solution wash water through the anion resin so that the gold particles are attached to the anion resin, and the gold recovery rate is relatively superior to the electrolysis method, but the adhesion rate to the anion resin is increased. It takes a long recovery time because it is slow, and in order to separate the gold attached to the anion resin, the anion resin has to be incinerated, resulting in a waste of resources and costs and generation of pollution.

It looks at the working state of the electrolytic gold recovery device (1) having a negative electrode filler according to the present invention having the above configuration.

The present invention uses an electrolysis method to recover the gold particles contained in the gold-containing treated water, the electrolysis is made in the drum to prevent the loss of the charge amount and the negative electrode (-) member 30 is a cathode current Is filled with a negative electrode filler (30a) such as a bowl (33) so as to become a conductor in the cathode network (31) through which electricity is energized, and the surface area for adsorbing gold particles is significantly expanded. will be.

In the above embodiment according to the present invention, the gold-containing treated water flows into the drum 10 by driving the pump 71 and flows toward the treatment tank 60 in the drum, and at the same time, the cathode from the positive electrode plate 23. Current flow toward the negative member 30 is generated.

The gold-containing treated water introduced into the drum 10 is coupled to citric acid by an electrical transmission force generated between the positive electrode plate 23 and the negative electrode member 30 while passing through the filter 17 and the positive electrode plate 23. The gold particles that were present are ionized to move and adsorb to the negative electrode member (30).

The negative electrode member 30 is filled with a negative electrode filler 30a such as a bowl 33, which becomes a conductor, in the negative electrode network 31 so as to influence the area where gold particles are adsorbed, that is, the gold recovery performance. The surface area of the cathode is increased tens to hundreds of times.

The negative electrode filler 30a such as the bowl 33, which becomes a conductor, is electrically connected to the negative electrode network 31 by its own weight to form a negative electrode. When the stirrer 37 is installed, the position of the bowl 33 is continuously maintained. Change to to ensure that the gold particles are evenly deposited on the entire surface and prevent the gold particles from falling off.

In addition, a plurality of electrode pairs are formed by forming a pair of electrodes with the cathode plate 23 in one drum 10 such that the cathode (-) member 30 is disposed closest to the primary electrode pair containing the gold-containing treated water inlet pipe. At this time, the gold is recovered by the electrical permeation force, and the gold particles are adsorbed and precipitated on the negative electrode (-) member of the primary electrode pair. In this state, the secondary electrode pairs and the third electrode pairs located next to each other are successively passed through, and the remaining gold particles are adsorbed and precipitated on the negative electrode (-) member, thereby significantly improving the gold recovery performance and treating the gold particles. Zero the number of gold particles remaining.

Looking at another embodiment (1A) according to the present invention, the treated water flowing into the first anode barrel 22 installed vertically from the inflow tank 81 is ejected to the front circumference through the through hole 223 of the first anode barrel 1, the gold particles ionized by electrotransmission while passing through the negative electrode member (30) formed by filling the negative electrode filler (30a) in the hollow cathode network (31a) vertically installed concentrically with the positive electrode (22) The treated water adsorbed and precipitated on the cathode (-) member and the gold particles are recovered is passed through the second cathode cylinder 24 and through the outlet 14 and the filter 17 formed in the bottom of the drum discharge discharge pipe 13 To be discharged.

In addition, when switching the circulation direction in the reverse direction, the mutual role of the discharge return pipe 13 and the inlet pipe 11 and the outlet tank 83 and the inlet tank 81 is changed, and through the outlet 14 of the drum bottom The treated water flows into the second anode cylinder 24, the hollow cathode network 31 a, and the first cathode cylinder 22.

Another embodiment (1A) of the present invention as described above is a negative electrode (-) member is a hollow cathode network (31a) is a negative electrode in which gold particles are precipitated primarily by vertically installed concentrically with the first positive electrode (22) The area of the (-) member is formed over a significantly wider area than the embodiment in which the positive electrode plate 23 is horizontally installed, so that the precipitated particles are distributed and deposited in a wide area and area, and the negative electrode (-) member due to the precipitation particles precipitates. The clogging phenomenon is prevented.

In addition, when any one of the first cathode cylinder 22, the second cathode cylinder 24, the hollow cathode network 31a, for example, the first anode cylinder is rotated by the drive means 51, the through hole 223 The treated water jetted through the head is more evenly directed to the hollow cathode network 31a, thereby increasing the efficiency of the current collection.

In another embodiment (1B) according to the present invention, the gold particles that are ionized by electrotransmitting force are transferred into the columnar cathode network while the gold-containing treated water passes between the columnar cathode network (31b) and the anode cylinder (26). Precipitated in the charged negative electrode filler (30a), there is an advantage that can expand the surface area of precipitation of gold particles in a very simple configuration.

In addition, the present invention is provided with an automatic electrolyte injection device 53 is controlled by the timer is supplied with electrolyte at a set time period to maintain the current flow in the best state, the temperature sensor and the temperature in the drum 10 A heater that is controlled on / off by a sensor is installed to maintain an optimal temperature for smooth electrolysis.

In addition, the control unit 90 includes a time switch and reverses the forward / reverse valve device 73 at a set time period to reversely reverse the circulation direction, thereby changing the flow direction of the gold-containing treated water in the drum 10, and thus the negative electrode. The gold particles are uniformly deposited on the whole surface of the negative member 30 without being biased to any one side, thereby preventing dropping due to the flow rate.

In addition, foreign substances generated from the hydrogen ion gas generated during electrolysis and citric acid contained in the plating solution are attached to the electrode of the positive electrode plate 23 and the negative electrode member 30 to weaken the electrolytic ionization degree as described above. By switching the circulating direction of the treated water, such hydrogen ion gas and foreign substances are dropped off and discharged from the electrode to maximize the electrolytic efficiency and the yield rate, and backwashing is performed to remove the foreign substances attached to the back surface of the filter 17.

In addition, two or more drums 10 in which the negative electrode filler 30a and the negative electrode member (-) are embedded are provided, and the gold-containing treated water circulation pipe 70 is gold-containing in the two or more drums 10. If the treated water is circulated sequentially, the recovery performance is maximized.

Separation of the gold particles deposited on the negative electrode member 30 may be used in various ways.

When the negative electrode filler 30a, such as the bowl 33, is made of steel 331 and the indium (In) 332 having a very low melting point of 156.63 ° C. is coated on the surface, separation and recovery of gold particles is easy. Let's do it.

When heating the bowl 33, the gold particles precipitated, only indium (In) 332 having a low melting point is melted to generate a space between the bowl made of steel 331 and the gold particles, and the gold particles are easily broken. do.

Put the bowl 33 in such a state in the barrel, and when the gold particles are broken down to pour out the water 33, and then to collect the gold by using a dense filter.

Indium (In), which is melted and separated from the bowl 33, is repeatedly reused as a coating material of the bowl.

As described above, the negative electrode charging member 30a for adsorption of gold particles according to the present invention, such as the bowl 33, is economically economical and does not generate pollution since the indium and the steel bowl are repeatedly reused, thereby reducing the environmental pollution.
