Description
Technical field
The new species of the anode the present invention relates to be used in electrolytic deposition.The present invention also relates to operate the electricity in metal
The method of the electrolysis cells used in solution deposition.
Electrolytic deposition is dissolved in the process that the metal of electrolyte is reduced on negative electrode by electric current.In electrolytic deposition,
Electric current passes through anode by the electrolyte solution comprising metal value (metal value), to cause to be sunk with electroplating process
Accumulate onto negative electrode and extract metal value.When electric current is applied to the electrolysis system based on sulfate, Metal deposition is in negative electrode
Surface on and water be decomposed to form on anode acid and oxygen.Electrolytic deposition occurs comprising the multiple sun arranged in an alternating manner
In the electrolysis cells of pole and multiple negative electrodes.The commercial Application of electrolytic deposition need substantial amounts of negative electrode in single electrolysis cells and
Anode.The a type of anode used in electrolytic deposition is lead-based anode, and the quality of copper of the lead-based anode to depositing has negative
Face acts on.Significantly have the disadvantage what is discharged from the surface of anode during electrolytic deposition operation using one of this lead-based anode
A small amount of lead, its undesirable particulate for causing to suspend in the electrolytic solution.In addition, lead precipitation must periodically (such as every 45 arrive
90 days) from unit bottom remove, electrolytic deposition unit is not produce metal during this time.
A problem in electrolyting precipitation process is at a relatively high cell voltage, causes increased energy ezpenditure.Due to
The low corrosion resistance of high energy and previous anode in electrolytic deposition, it has been necessary to which research is more preferable in electrolytic deposition
Anode material.The anode of coating mixed-metal oxides (MMO) is applied by the conductive mixed-metal oxides on valve metal substrate
Layer composition, typically titanium or nickel.The anode of dimensionally stable orIt is the anode type of well-known coating MMO.
When in the electrolytic deposition based on sulfate using the anode of coating MMO, can be lower than when using lead-based anode
Operating unit at cell voltage.The anode of a type of dimensionally stable sees patent and discloses US4134806, and wherein idea is logical
Cross the CURRENT DISTRIBUTION for making the DSA anode constructions in border area thickening with stabilization between DSA anodes and negative electrode.Open US
20100276281 give for the anode in electrolytic deposition unit.According to the disclosure, electrode includes suspension bar, including at least
The sealing of the electrode body of one stub and substrate, the connection of coupling suspension bar and at least one stub, and isolation connection.
Electrode includes suspension bar, electrode body and substrate, and suspension bar includes at least one shrinkage pool, and electrode body enters institute including press-in cooperation
At least one of at least one shrinkage pool stub is stated, and substrate is couple to stub.
Past research and development concentrates on the mode for increasing the copper electrodeposition production capacity per device area, and its is straight
Connect the cost benefit of influence electrolyting precipitation process.To increase the production of electrolysis installation and unit, increase electric current during electrolysis
Density and the sedimentation rate that copper high is obtained on negative electrode are desirable.The current density of cathode side is limited to the copper of deposit
Quality, this be due on negative electrode overvoltage increase, as the more impurity of the increase of current density are deposited.In addition, increasing
Power-up current density also causes the increase of the corrosion rate of the lead from lead anode, thus more lead circulations are in the electrolytic solution, and
And lead can be included in the cathode, it is desirable to increase the frequency of cleaning unit to control lead and reduce productivity ratio.
Due to negative electrode processing unit (plant) and the with high investment and running cost of electrolysis unit including crane and stripping machine, in institute
Crane and stripping machine are to combine in the tank house of meaning, are electrolysed both in raising refining electrolysis and extraction/electrolytic deposition
Trial of business efficiency aspect reasonable time carried out.This efficiency for being heavily dependent on electrolysis and movable cathode
Number of times and it is accordingly dependent on the amount of each cathode deposition copper.A kind of mode for reducing tank house capital cost is cloudy by increasing
The length of pole, therefore need not increase current density, improved per single in the case of the quantity of plant area or electrolysis cells
The production capacity of unit.
Open WO 2005/080640 gives the technique for electrochemical electrolysis or refined copper, wherein the idea invented
It is the copper load for increasing each negative electrode.In order to increase the business efficiency of such technique and device, according to the disclosure, propose in electricity
At least one negative electrode is submerged at least 1.2 meters in electrolyte of length during solution operation.
Problem still may occur when the negative electrode using big length.When with huge negative electrode (i.e. big length
Negative electrode) when being used together lead anode, the bending of anode may occur during electrolytic deposition and come short-circuit to process bands.Especially
Its for unit in first and last anode there may be problem, wherein electric current only flows in the side of anode, this
May be bent to anode strap or creep.Bending causes the increase of short-circuit quantity and low current efficiency.If lead anode and
Huge negative electrode is used together, it is necessary to the maintenance of frequent electrolysis cells is precipitated with removing lead from unit.In addition, for equal
Even CURRENT DISTRIBUTION, with equal Distance positioning anode is beneficial from negative electrode.In order to avoid such problem or problem, need
The anode of the new species being used together with negative electrode long is developed, anode has rigid structure and is located in the cells correct
Position.
Target of the invention
