Definitions

  • the present invention relates to a scandium concentrate production method, and in more detail, relates to a method of reusing an alloy containing scandium and aluminum as aluminum and scandium concentrates.
  • Aluminum scandium alloys containing aluminum and scandium have a characteristic of being light weight and high strength, and in addition to sports articles, have been used in fields requiring shock resistance. Additionally, in the future, applications as a structural material for aircraft, electric vehicles, high-speed rail, etc. are also expected. However, since the production volume of scandium is very small, scandium is extremely high cost. For this reason, it is not easy to broadly apply scandium industrially.
  • Patent Document 1 Japanese Unexamined Patent Application, Publication No. 2003-171724
  • the scandium quality of these disposed articles, etc. is far higher than the scandium quality of nickel oxide ores, etc., and recovering scandium from the disposed articles, etc. and reusing is expected to be an effective means.
  • an element contained in Al-Sc alloy is aluminum, and the content of scandium is a very small amount comparing with the content of aluminum; therefore, it is not possible to effectively recover scandium concentrate by simply melting Al-Sc alloy.
  • the present invention has been made in order to solve the above such problems, and the object thereof is to effectively recover scandium concentrate from Al-Sc alloy.
  • the Al-Sc alloy in structures, etc. is widely used by concentrating to 0.1 to 1% Sc.
  • the Sc concentration of the Al-Sc master alloy is 1 to 2%.
  • the present invention has an object of efficiently recovering scandium concentration of a degree that can be used as is as an Al-Sc master alloy from scrap articles of Al-Sc alloy having a Sc concentration on the order of 0.1 to 1%.
  • the present inventors found that the above-mentioned object could be achieved by bringing chlorine into contact with an alloy containing aluminum and scandium, and melting, followed by subjecting the molten mixture to electrolysis at predetermined conditions, thereby arriving at completion of the present invention.
  • the present invention provides the following matters.
  • a first aspect of the present invention is a scandium concentrate production method, including: a molted mixture generation step of generating a molten mixture of aluminum chloride and scandium chloride by bringing chlorine into contact with an alloy containing aluminum and scandium, and melting; a first electrolysis step of subjecting the molten mixture to first electrolysis at a potential between the metalation potential of aluminum and the metalation potential of scandium to generate molten aluminum; and a second electrolysis step of subjecting the molten mixture, after the molten aluminum generation step, to second electrolysis at a potential capable of recovering scandium to generate a scandium concentrate.
  • the molten mixture generation step is a step of melting the alloy brought into contact with the chlorine into a melt of a chloride-based salt or eutectic salt having a melting point or eutectic temperature higher than 500°C.
  • This scandium concentrate can be used as is as a high-quality Al-Sc master alloy.
  • FIG. 1 is a schematic view showing a scandium concentrate production method according to the present invention.
  • the present method includes: a molten mixture generation step S1 of generating a molten mixture of aluminum chloride and scandium chloride by bringing chlorine into contact with an alloy containing aluminum and scandium and melting; a first electrolysis step of subjecting the molten mixture to first electrolysis at a potential between the metalation potential of aluminum and the metalation potential of scandium; and a second electrolysis step of subjecting the molten mixture, after the molten aluminum generation step S2, to second electrolysis at a potential capable of recovering scandium to generate a scandium concentrate.
  • the molten mixture generation step S1 brings chlorine gas into contact with an Al-Sc alloy serving as a raw material (disposed articles, manufacturing defect articles, etc.), to obtain a mixture of aluminum chloride and scandium chloride.
  • the contact temperature with chlorine gas is not particularly limited.
  • the present invention uses a molten salt electrolysis method to melt an ionic solid by bringing to high temperature, and then electrolyzing this.
  • the molten salt In the view of the melting point of aluminum being 660.5°C, and heating the molten salt to a temperature higher than this melting point, it is necessary for the molten salt to have a melting point or eutectic temperature higher than 500°C.
  • the vapor pressure of the chloride increases by the activity of the salt rising accompanying an increase in temperature, when the melting point or eutectic temperature is remarkably low compared to the melting point of aluminum, due to heating up to a temperature higher than the melting point of aluminum upon electrolysis, and thus the volatilization of salt will occur.
  • the salt composition gradually changes by way of this volatilization, and the electrolytic voltage continually changes accompanying this; therefore, it is difficult to appropriately control electrolysis. For this reason, it is not preferable to use a molten salt having a melting point or eutectic temperature that is remarkably low compared to the melting point of aluminum.
  • the eutectic temperature of the LiCl-KCl eutectic salt is 350°C, and it is not preferable because the eutectic temperature is remarkably low compared to the melting point of aluminum.
  • molten salt having a melting point or eutectic temperature close to the melting point of aluminum, in the point of not requiring to heat more than necessary upon electrolysis.
  • the molten salt requires there to be a difference of at least 0.8 V between the metalation potential of aluminum and the metalation potential of scandium.
  • the electrolytic potentials of elements differ according to the type and composition of molten salt. Due to aluminum and scandium coexisting, the present invention configures so that only aluminum is generated in the first electrolysis, and scandium is first generated in the second electrolysis; therefore, the molten salt requires to have at least a certain difference between the metalation potential of aluminum and the metalation potential of scandium. A greater difference is preferable, it is more preferably at least 1.0 V, and even more preferably at least 1.2 V.
  • the metalation potential of Al 3+ is -1.04 V
  • the metalation potential of Sc 3+ is -1.83 V.
  • the difference between the two is about 0.8 V, and thus is sufficient to suppress both aluminum and scandium generating in the first electrolysis.
  • detailed data for the metalation potential is not known, even if the type of metal element constituting the salt differs, a great difference in the metalation potentials will not arise so long as being chloride-based salts.
  • the heating temperature of the molten salt is sufficient so long as an extent able to sufficiently melt the Al-Sc alloy.
  • the liquidus temperature of the Al-Sc alloy will differ according to the scandium concentration contained in the Al-Sc alloy.
  • the liquidus temperature of the Al-Sc alloy is determined by referencing a published phase diagram of Al-Sc alloy. For example, in the case of the scandium concentration being on the order of 0.2 to 0.4%, the liquidus temperature of the Al-Sc alloy is on the order of 660°C, which is the eutectic temperature.
  • the liquidus temperature rises as the scandium concentration contained in the Al-Sc alloy increases, and the liquidus temperature in the case of the scandium concentration being 1% is about 730°C, and the liquidus temperature in the case of being 2% exceeds 800°C.
  • the above-mentioned mixture i.e. mixture of aluminum chloride and scandium chloride
  • the first electrolysis step S2 subjects the molten mixture obtained in the molten mixture generation step S1 to the first electrolysis at a potential between the metalation potential of aluminum and the metalation potential of scandium to generate molten aluminum.
  • the type of electrode is not particularly limited, for example, establishing silver as the reference electrode, graphite as the anode, and nickel as the cathode can be exemplified.
  • the potential in the first electrolysis is required to be between the metalation potential of aluminum and the metalation potential of scandium, and in more detail, no more than the metalation potential of aluminum and at least the metalation potential of scandium. If not in this range, it is not preferable because not only molten aluminum, but also scandium can also generate at the cathode.
  • the potential in the first electrolysis is preferably closer to the metalation potential of aluminum, and specifically, is preferably within the range of -1.50 V to -1.04 V, and is more preferably within the range of -1.30 V to -1.10 V.
  • the temperature of the molten salt is not particularly limited so long as higher than the melting point of aluminum.
  • the first electrolysis it is preferable to store the aluminum in a storage container along with molten salt in advance.
  • the interior of the storage container is heated up to a temperature higher than the melting point of aluminum; therefore, the stored aluminum is used as an aluminum electrode (cathode) through the above-mentioned nickel.
  • new aluminum produced in the electrolysis of the Al-Sc alloy melts into the aluminum that had already melted. As a result thereof, the concentration of scandium contained in the molten salt rises.
  • the second electrolysis step S3 subjects the molten mixture to the second electrolysis at a potential capable of recovering scandium, after the molten aluminum generation step S2. By doing this, the liquid scandium dissolves in the liquid aluminum obtained in the first electrolysis, and a scandium concentrate is generated.
  • the type of electrode is not particularly limited, and the same one as the electrode used in the first electrolysis can be used.
  • the potential in the second electrolysis is required to be capable of recovering scandium, and be no more than the metalation potential of scandium. If not in this range, it is not preferable because liquid scandium will not dissolve in the liquid aluminum obtained in the first electrolysis at the cathode.
  • the potential in the second electrolysis is sufficient so long as no more than -1.83 V, when considering the stability of the operation, it is preferably no more than -2.0 V.
  • the amount of aluminum stored in advance inside the storage container can be arbitrarily set according to the target scandium quality for the scandium concentrate.
  • the temperature of the molten salt is not particularly limited so long as higher than the temperature of the liquidus of the Al-Sc alloy contained in the molten salt; however, based on the stability of the operation, etc., it is preferably at least 5°C higher than the temperature of the liquidus of the Al-Sc alloy, and more preferably at least 10°C higher.
  • the scandium concentrate of the present invention may be reused as is as a high-grade Al-Sc master alloy, or may be reused after remelting and making into a master alloy.
  • by recovering scandium from a scandium concentrate by a known method such as solvent extraction it is possible to very efficiently recover scandium compared to a case of recovering from nickel oxide ore.
  • FIG. 2 is a schematic view illustrating the configuration of the electrolysis apparatus 1 used in the present Examples.
  • the electrolysis apparatus 1 includes: a quartz container 2 that encloses the Al-Sc alloy along with molten salt; a quartz tube 3 with one side open, and accommodating the quartz container 2 from this opening; a rubber stopper 4 that seals this quartz tube 3; a reference electrode (silver) 5, anode (graphite) 6 and cathode (nickel) 7 inserted inside of the quartz container 2; a gas substitution unit 8 that substitutes the inside of the quartz tube 3 with argon gas; a thermocouple 9 that is inserted inside of the quartz container 2; an electric furnace 10 that keeps the temperature inside of the quartz tube 3 at a predetermined temperature; and an insulation board 11 that keeps the adiabaticity of the inside of the quartz tube 3.
  • the reference electrode (silver) 5, the anode (graphite) 6 and the cathode (nickel) 7 were immersed to the positions shown in FIG. 2 , and the first electrolysis was performed while holding at the potential of -1.25 V for the potential of the Ag + /Ag reference electrode 5.
  • Aluminum was thereby recovered from the bottom of the quartz container 2 through the cathode 7.
  • the inside of the quartz tube 3 was heated to 880°C, and the second electrolysis was performed.
  • the inside of the quartz tube 3 was cooled to room temperature. Then, the salt 12 (mixture of aluminum and NaCl-KCl eutectic salt) and scandium concentrate 13 that solidified from cooling were retrieved.
