- Patent Document 1 discloses a method capable of recovering about 80% of valuable metals such as nickel and cobalt by using a high-temperature heating furnace, adding flux to a waste battery, and repeatedly treating slag. Yes.
- carbon is contained in the vicinity of the center of a waste battery as a negative electrode material for a lithium ion battery. Therefore, it is difficult to strictly control the oxidation in the melting process, and the degree of oxidation tends to vary. The variation sometimes hinders proper oxidation promotion or suppression of other substances in the melt, making the entire oxidation treatment unstable. That is, in order to recover valuable metals stably, it is necessary to oxidize carbon stably.
- the present invention has been made to solve the above-described problems, and an object of the present invention is to provide a valuable metal recovery method capable of stably increasing the recovery rate in recovering valuable metals from waste batteries by a dry method. There is.

This makes it possible to recover valuable metals at a stable and high recovery rate.
- FIG. 1 is a flowchart showing an example of a valuable metal recovery method from a waste battery.
- the waste battery is a lithium ion battery
- the present invention is not limited to this.

- what is necessary is just to include a waste battery in the process target, and adding other metals, resin, etc. other than a waste battery suitably is not excluded. In that case, it is a waste battery of the present invention including other metals and resins.
- the waste battery pretreatment step ST10 is performed for the purpose of preventing explosion of the waste battery. That is, since the waste battery is a closed system and has an electrolytic solution or the like inside, if the dry melting process is carried out as it is, there is a risk of explosion, which is dangerous. For this reason, it is necessary to perform an opening process for degassing by some method. This is the purpose of performing the waste battery pretreatment step ST10.
- the specific method of the waste battery pretreatment step ST10 is not particularly limited.
- the waste battery may be physically opened with a needle-like blade edge.
- a melting process is performed in the subsequent dry processing, separation of individual members or the like is not necessary.
- the pre-oxidation step ST20 that is a feature of the present invention will be described.
- oxidation treatment is performed by supplying oxygen while roasting the pretreated waste battery obtained in the waste battery pretreatment step ST10 at a temperature of 600 ° C to 1250 ° C.
- oxidation treatment is performed in the melting step in the dry process.
- the preliminary oxidation step ST20 is provided before the melting step ST21, and the preliminary oxidation is performed in advance. It is characterized by processing.
- This pre-oxidation treatment is performed before the melting step ST21 in the dry process S20, and is performed in the preliminary oxidation furnace by providing a pre-oxidation furnace separately from the melting furnace performing the melting step ST21.
- a kiln can be used as the preliminary oxidation furnace.
- a rotary kiln that has been conventionally used for cement production or the like can be suitably used, so the rotary kiln will be described in detail below as a representative example of the kiln, but the kiln in the present invention is described below. Not limited to this.
- it includes all types of kilns such as a tunnel kiln (Heath Furnace) that can be oxidized inside by supplying oxygen while roasting waste batteries in the preliminary oxidation step ST20.
- a tunnel kiln Heath Furnace

- a drive gear 11 is provided outside the kiln body 10 to transmit the rotational force to the kiln body.
- a burner pipe 12 for blowing hot air for heating the inside is provided in the kiln main body.
- the kiln body 10 provided with these is installed so as to have an inclination of 3 to 4% with respect to the horizontal plane in use.

- the waste battery is carried in from the carry-in port 13 in the A direction.
- the waste battery moves in the kiln body 10 toward the discharge port 14 while being stirred and roasted along the inclination of the kiln body 10.
- the temperature in the kiln main body 10 is less than 600 ° C., the oxidation does not proceed sufficiently, which is not preferable.
- the temperature in the kiln main body 10 exceeds 1250 ° C.
- a part of iron or the like mainly used for the outer shell of the waste battery melts and adheres to the inner wall of the kiln main body 10, so that smooth operation is possible. This is not preferable because it may hinder the deterioration of the kiln itself.
- an oxidant such as air is added to the kiln body 10.
- aluminum foil is used as a positive electrode material for lithium ion batteries. Carbon is used as the negative electrode material.
- the outer shell of the battery is made of iron or aluminum, and plastic is used for the outer package of the assembled battery. These materials basically act as a reducing agent. For this reason, the total reaction for converting these materials into gas or slag is an oxidation reaction. Therefore, it is necessary to introduce oxygen into the kiln body 10. This is why air is introduced in the pre-oxidation step ST20.
- the oxidizing agent is not particularly limited, but from the viewpoint of easy handling, a gas containing oxygen such as air, pure oxygen, and oxygen-enriched gas is preferably used. These are fed directly into the kiln body 10 in the preliminary oxidation step ST20.
- the introduction amount of the oxidizing agent is approximately 1.2 times the chemical equivalent required for the oxidation of each substance to be oxidized.
- the waste battery oxidized through the above process is discharged from the discharge port 14 in the B direction.
- the exhaust gas generated during the oxidation process is discharged in the C direction.
- the preliminary oxidation step ST20 in the present invention is an oxidation treatment at a lower temperature than the case where the oxidation treatment is performed in the melting step ST21, the reaction rate is relatively slow, and the cylindrical kiln body 10
- This is a method of oxidizing a waste battery moving through the kiln main body 10 by introducing a predetermined amount of oxygen into the space, so that the oxidation can be easily controlled by adjusting the amount of oxygen, oxidation time, temperature, etc. It is.
- Carbon which often impairs the stability of the overall oxidation treatment, can be easily controlled for oxidation unlike the case where the oxidation treatment is performed in the melting step in the dry process.
- this preliminary oxidation step ST20 the oxidation treatment is performed to such an extent that almost all the carbon is oxidized. Thereby, the dispersion
- the main elements constituting the material of the waste battery are generally oxidized in the order of aluminum> lithium> carbon> manganese> phosphorous> iron> cobalt> nickel> copper due to the difference in affinity with oxygen. That is, aluminum is most easily oxidized and copper is most hardly oxidized.
- the oxidation degree of iron is increased. At the same time, it is required to strictly adjust the degree of oxidation to suppress cobalt oxidation.
- the preliminary oxidation step ST20 it is possible to adjust the degree of oxidation more strictly than in the case where the oxidation treatment is performed in the melting step in the dry process.
- ⁇ Dry process S20> In the dry process S20, a melting process ST21 is performed in which the waste battery that has been oxidized in the preliminary oxidation process ST20 is melted at about 1500 ° C. Melting process ST21 can be performed with a conventionally known electric furnace or the like.
- the oxidation process is performed in advance in the preliminary oxidation process ST20, it is not necessary to perform the oxidation process on the waste battery melted in the dry process as in the prior art.
- an additional oxidation step for performing additional oxidation treatment for a very short time can be provided in the melting step ST21.
- This additional oxidation step makes it possible to control the degree of oxidation more finely.
- the additional oxidation process can be performed in a very short time compared to the conventional oxidation process at the time of melting, so there is little adverse effect on work efficiency and less lance consumption, resulting in a problem of cost increase. Hateful.
- SiO 2 silicon dioxide
- CaO limestone
- the melting step ST21 produces slag, which is an oxide such as iron or aluminum, and an alloy of nickel, cobalt, or copper as valuable metals. Since they have different specific gravities, they are recovered by slag separation ST22 and alloy separation ST23, respectively. At this time, if the content of aluminum oxide in the slag is relatively large, a slag having a high melting point and a high viscosity is obtained. However, as described above, SiO2 and CaO are added to lower the melting point of the slag in the melting step ST21. Therefore, the viscosity can be reduced by lowering the melting point of the slag. For this reason, slag separation ST22 can be performed efficiently. Note that dust, exhaust gas, and the like in the melting step ST21 are detoxified in a conventionally known exhaust gas treatment ST24.
- a dephosphorization step ST25 is further performed on the obtained alloy.
- ethylene carbonate and diethyl carbonate in an organic solvent such as, such as LiPF 6 as the lithium salt (lithium hexafluorophosphate) is used as the electrolyte.
- LiPF 6 lithium salt
- phosphorus in this LiPF 6 has the property of being relatively easily oxidized, it has a property of relatively high affinity with iron group elements such as iron, cobalt and nickel.
- Phosphorus in the alloy is difficult to remove in the subsequent wet process of recovering each element as a metal from the alloy obtained by the dry process, and accumulates as impurities in the processing system, so that the operation cannot be continued. For this reason, it is removed in this dephosphorization step ST25.
- phosphorus in the alloy can be oxidized and absorbed in CaO by adding lime or the like that generates CaO by reaction and blowing in an oxygen-containing gas such as air.
- the alloy obtained in this way is composed of cobalt, nickel derived from the positive electrode material, lithium derived from the electrolyte, copper derived from the conductive material of the negative electrode, and the like.
- the dry process and the wet process by obtaining an alloy with few impurities by making the dry process a broad pretreatment and also greatly reducing the amount of processing to be put into the wet process.
- the wet process is basically a complicated process that is not suitable for mass processing, it is necessary to perform the processing time of the wet process, in particular, the dissolution process ST31 in a short time in order to combine with the dry process.
- the melting time can be shortened by granulating the alloy.
- the average surface area in terms of the surface area is 300 mm 2 from 1 mm 2, it is preferable from 0.4mg Speaking in average weight in the range of 2.2 g. If it is less than the lower limit of this range, it is not preferable because the particles are too fine and difficult to handle, and further, the reaction is too early and it becomes difficult to dissolve at once due to excessive heat generation. If the upper limit is exceeded, the dissolution rate in the subsequent wet process decreases, which is not preferable.
- a method of granulating the alloy by shot a conventionally known method of quenching by inflow of molten metal into flowing water can be used.
- a valuable metal recovery process from a waste battery is meaningless if it is recovered as an alloy as in Patent Document 1, and needs to be recovered as a valuable metal element.
- an alloy of only valuable metals as described above can be used to simplify the subsequent wet process.
- the wet processing amount is reduced from about 1 ⁇ 4 to about 3 in mass ratio as compared with the amount of the input waste battery.
- the wet process can use a conventionally known method and is not particularly limited.
- a conventionally known method for example, in the case of an alloy composed of cobalt, nickel, copper, and iron when the waste battery is a lithium ion battery, after acid dissolution (dissolution step ST31), iron removal, copper separation recovery, nickel / cobalt separation, Valuable metal elements can be recovered through the element separation step ST32 in the procedures of nickel recovery and cobalt recovery.
- the oxidation process was performed in a state where the waste battery was melted in the dry process, so in order to appropriately adjust the degree of oxidation in the oxidation process,
- the melting process was required to be a batch process in which the next process was started again from the beginning after the oxidation process of all the waste batteries simultaneously processed in the furnace was completed.
- the waste battery that has been previously oxidized in the preliminary oxidation step ST20 can be continuously treated in the dry process by continuously charging the waste battery in the melting furnace. A larger amount of processing is possible.
- the present invention can be suitably used when it is at least 1 t or more per day, preferably 10 t or more per day.
- the type of waste battery is not particularly limited, but a rare metal such as cobalt or lithium can be recovered, and its use has been expanded to automobile batteries, etc., and a lithium ion battery that requires a large-scale recovery process is the present invention. It can illustrate preferably as a process target.
- Example 1 the preliminary oxidation process was provided prior to the melting process to perform the preliminary oxidation process, and then the melting process was provided to perform the melting process.
- samples 21 to 25 g of waste lithium ion batteries (hereinafter referred to as “samples”) were heated at 900 ° C., 1100 ° C., as shown in Table 1, by heating in an alumina crucible with a nitrogen atmosphere.
- a preliminary oxidation treatment was performed by blowing each predetermined amount of oxygen shown in Table 1 through an alumina tube while maintaining the temperature at 1200 ° C. for 30 minutes.
- Example 2 a predetermined amount of air was blown in place of oxygen.
- a mixed flux having a SiO 2 / CaO ratio of 1 was added to a sample in an alumina crucible oxidized by a pre-oxidation treatment, and then the sample was heated to a temperature in a nitrogen atmosphere and changed to Table 1. As shown, it was melted at a temperature within the range of 1450 ° C. to 1500 ° C. and held for 1 hour to perform the melting treatment. At this time, oxygen was not blown.
- Comparative Examples 1 to 3 the preliminary oxidation treatment was not performed, the process was shifted to the melting step, and the oxidation treatment was performed during the melting treatment.
- Comparative Example 4 the preliminary oxidation treatment was performed at a temperature of 1300 ° C.
- Comparative Examples 1 to 3 as the first step, the same amount of the sample as in the example was placed in an alumina crucible by heating in a nitrogen atmosphere as shown in Table 1, as shown in Table 1. Hold for 30 minutes at a temperature of ° C. However, unlike the example, oxygen blowing, that is, pre-oxidation treatment was not performed in this step.
- Comparative Example 4 the same amount of the sample as in the example was placed in an alumina crucible, and as in the example, the temperature was maintained at 1300 ° C. for 30 minutes as shown in Table 1 while maintaining the temperature in a nitrogen atmosphere.
