Es verursacht nur geringe Investitions- und Betriebskosten und lässt sich sehr einfach in die Betriebsabläufe von Geothermie- und Erdgasförder-Anlagen integrieren.The invention relates to a plant for the production of lithium concentrate from brines, as they occur in the field of deep geothermal or natural gas production. The invention utilizes the sorption of lithium ions to a sorbent and the desorption by changing the ionic strength of brine conditions to fresh water. The system is simple and easy to operate even under remote conditions.

Description
Der Bedarf an Lithium als Rohstoff wächst stark aufgrund neuer Anwendungen wie z.B. Lithium-Ionen-Batterien. Lithium wird in der Regel als Lithium-Carbonat oder dessen Äquivalente vermarktet (LCE = Lithium Carbonate Equivalent). Bislang wird Lithium aus Lithium-haltigem Erz oder aus Solen gewonnen. Die Gewinnung aus Sole hat dabei einen Preisvorteil. Die Sole wird nach dem Stand der Technik konzentriert und dann das Lithium mittel Zugabe von Natrium-Hydrogencarbonat zu Lithium-Carbonat gefällt. Die Konzentration erfolgt meist durch Verdampfen mittels Sonnenkraft in Teichen. An den bisherigen Standorten in Wüstengebieten ist dieses Verfahren kostenoptimal.The demand for lithium as a raw material is growing strongly due to new applications such as e.g. Lithium-ion batteries. Lithium is usually marketed as Lithium Carbonate or its equivalents (LCE = Lithium Carbonate Equivalent). So far, lithium is obtained from lithium-bearing ore or sols. The extraction of brine has a price advantage. The brine is concentrated in the prior art and then the lithium is precipitated by adding sodium bicarbonate to lithium carbonate. The concentration usually takes place by evaporation by solar power in ponds. At the previous locations in desert areas, this procedure is cost-optimal.
Mittlerweile werden jedoch auch hohe Gehalte in Solen berichtet, die in Nicht-Wüstengebieten anfallen, z.B. im Zuge der Energiegewinnung aus tiefer Geothermie oder als Reststoff des Erdgas-Frackings. Hier sind energieaufwendigere Verfahren der Aufkonzentration angewandt worden, wie die Trennung mittels ionenselektiven Membranen oder durch Sorption an Kationen-Tauschem und der Desorption mittels ionischen Lösungen oder Säure. Diese Verfahren haben den Nachteil hoher Anlageninvestitionen, hoher Betriebsmittelkosten und unliebsamer Reststoffe / Regenerate.Meanwhile, however, high levels are also reported in sols arising in non-desert areas, e.g. in the course of energy production from deep geothermal energy or as a residue of the natural gas fracking. More energy consuming methods of concentration have been used here, such as separation by means of ion-selective membranes or by sorption on cation exchanges and desorption by means of ionic solutions or acid. These processes have the disadvantage of high capital investment, high equipment costs and unpleasant residues / regenerates.
Das erfindungsgemäße Verfahren beseitigt diese Nachteile. Es ermöglicht die Gewinnung eines Lithium-Konzentrates auf sehr einfache Weise, ohne dass maßgeblich in den Standardbetrieb der Geothermieanlage oder der Erdgasprooduktion eingegriffen werden muss. Die Investitionskosten sind sehr niedrig und der Bedienaufwand ist unaufwendig und kostengünstig. Es werden keinerlei teure Einsatzstoffe benötigt und Abfallströme fallen nicht an.The method according to the invention eliminates these disadvantages. It makes it possible to obtain a lithium concentrate in a very simple manner, without having to significantly intervene in the standard operation of the geothermal plant or the natural gas production. The investment costs are very low and the operating costs are inexpensive and inexpensive. No expensive starting materials are needed and waste streams do not accumulate.
Das erfindungsgemäße Verfahren nutzt die Tatsache, dass Lithium-Ionen bei extrem hohen Salzkonzentrationen einer Sole weitaus besser an Oberflächen binden als unter Süßwasserbedingungen. So lässt sich ein erstaunlich einfaches Trenn- und Konzentrationsverfahren für Lithium realisieren.The process according to the invention utilizes the fact that lithium ions bind much better to surfaces at extremely high salt concentrations of a brine than under freshwater conditions. This makes it possible to realize an amazingly simple separation and concentration process for lithium.
Das erfindungsgemäße Verfahren sieht die Durchströmung eines granulären Sorbens mit Sole vor. Charakteristisch für das erfindungsgemäße Verfahren ist dabei der sequentielle Wechsel von Durchströmung mit Sole hoher Salzkonzentration und Waschung mittels Süßwasser mit sehr geringer Salzkonzentration. Der Wechsel der Salzkonzentration ermöglicht dabei erfindungsgemäß die Desorption des Lithiums.The inventive method provides the flow through a granular sorbent with brine. Characteristic of the method according to the invention is the sequential change of flow with brine high salt concentration and washing by means of fresh water with very low salt concentration. The change of the salt concentration according to the invention allows the desorption of lithium.
Durch langsames Durchströmen wird den Lithium-Ionen die Bindung am Sorbens ermöglicht. Die Sole verlässt den Bereich des durchströmten Sorbens lithiumabgereichert. Nach einem relativ langen Durchströmungszeitraum wird der Solestrom für kurze Zeit angehalten oder über eine Bypass geführt. Jetzt kann das Sorbens kurz mit zur Sole isotonischer NaCI-Lösung gewaschen/durchströmt werden, um störende Ionen wie Magnesium, Srontium, oder Barium zu entfernen.By slowly flowing through the lithium ions, the bond is made possible on the sorbent. The brine leaves the area of the flowed sorbent lithium-depleted. After a relatively long flow period, the brine flow is stopped for a short time or passed through a bypass. Now the sorbent can be briefly washed / flowed through to the brine of isotonic NaCl solution to remove interfering ions such as magnesium, Srontium, or barium.
Im nächsten Schritt, wird das Sorbens mit Süßwasser gewaschen/durchströmt. Dadurch gehen die schwach sorbierten Lithium-Ionen in Lösung. Da die Süßwasser-Waschlösung nur einen Bruchteil des Volumens der zuvor durchströmten Sole benötigt, wird eine starke Konzentrationserhöhung in der Süßwasser-Waschlösung im Vergleich zur Sole erzielt. Die Waschlösung kann somit als Lithium-Konzentrat gesammelt und weiter verarbeitet werden. Dies ermöglicht im Folgeschritt die kostengünstige Gewinnung von Handelsprodukten wie Lithiumcarbonat (LCE) durch einfache Fällung mit Natrium-Carbonaten.In the next step, the sorbent is washed / flowed through with fresh water. As a result, the weakly sorbed lithium ions go into solution. Since the fresh water wash solution requires only a fraction of the volume of the previously flowed brine, a strong increase in concentration in the fresh water wash solution compared to brine is achieved. The washing solution can thus be collected as lithium concentrate and processed further. This allows the subsequent production of cost-effective production of commercial products such as lithium carbonate (LCE) by simple precipitation with sodium carbonates.
Die Funktionsweise kann über das unterschiedliche Verhalten der Hydrat-Schalen der Ionen in Sole und Süßwasser erklärt werden (
Das Sorbens soll erfindungsgemäß eine Bindungsstärke aufweisen, die in der Sole eine Bindung ermöglicht, unter Süßwasserbedingungen jedoch nicht. Um die Ablösung zu gewährleisten sollen Sorbenzien mit vergleichsweise geringer Bindungsstärke verwendet werden, z.B. CaCO3- oder MgCO3-Granulat. Dieses kann aus Kalk oder Dolomit preiswerte hergestellt werden. Es ist unbegrenzt verfügbar und ökologisch verträglich. Weitere massenverfügbare Sorbenzien können Tone oder Lehme sein, Böden oder organische Materialien wie Komposte.According to the invention, the sorbent should have a bond strength which allows bonding in the brine, but not under freshwater conditions. To ensure separation, sorbents with comparatively low bond strength are to be used, for example CaCO 3 or MgCO 3 granules. This can be made from lime or dolomite inexpensive. It is available unlimited and ecologically sound. Other mass-available sorbents may be clays or loams, soils or organic materials such as compost.
Die Sorption kann als Festbettreaktor in kleinen Teichen durchgeführt werden. Dazu können vorzugsweise Teiche genutzt werden, die zur Zwischenspeicherung der geförderten Sole bereits verwendet werden (
Das zur Desorption und Konzentration verwendete Süßwasser kann einen neutralen pH-Wert haben oder mittels Säure oder einem sauer eingestellten Puffersystem angesäuert sein. Weiterhin können ihm Reinigungs- und Konditionierungssubstanzen beigegeben werden.The fresh water used for desorption and concentration may have a neutral pH or be acidified by acid or an acidified buffer system. Furthermore, cleaning and conditioning substances can be added to it.
Vorzugsweise können mehrere unterschiedlich angereicherten Fraktionen zur Spülung genutzt werden, die in den vorherigen Spülzyklen erzeugt wurden, vorzugsweise drei Fraktionen. Erfindungsgemäß wird zunächst mit der höchstkonzentrierten Li-Lösung gespült, dann mit der niedriger Konzentration und danach mit Süßwasser. Die höchstkonzentrierte Lösung wird danach als Konzentrat zur Weiterbehandlung verwendet, vorzugsweise zur Fällung mittels NaHCO3-Fälligung, die beiden weiteren stehen für die nächste Auswaschung zur Verfügung.Preferably, several differently enriched fractions can be used for rinsing, which were generated in the previous rinse cycles, preferably three fractions. According to the invention, the solution is first rinsed with the highly concentrated Li solution, then with the lower concentration and then with fresh water. The highly concentrated solution is then used as a concentrate for further treatment, preferably for precipitation by NaHCO 3 precipitation, the other two are available for the next leaching.
