“…Sebaliknya, jika sumber daya manusia yang dimiliki tidak dapat mengolahnya maka kekayaan alam tersebut hanya akan menjadi sebuah potensi yang tidak berkembang dan belum mampu untuk dimanfaatkan. Penyebaran mineral di Indonesia tidak merata sesuai dengan kondisi geologi di masing-masing wilayah (Purwanti et al 2020;Astuti et al 2021). Di daratan Indonesia yang luasnya 2.027.087 km 2 tersebar berbagai sumber daya alam seperti mineral, hutan, air, dan manusianya sendiri (Sumaatmadja 1988).…”

Salah satu sumber daya mineral yang berperan penting dalam kehidupan masyarakat di dunia adalah timah. Sumber daya timah dapat diolah menjadi timah sulfat yang memiliki nilai jual dan manfaat yang lebih tinggi. Timah(II) sulfat digunakan dalam aplikasi industri dan manufaktur sebagai agen elektroplating dan produk perawatan permukaan logam. Permintaan timah sulfat di pasar global mengalami peningkatan yang signifikan. Beberapa metode produksi timah sulfat telah dikembangkan untuk meningkatkan kualitas sumber daya timah. Tujuan utama dari penelitian ini adalah untuk mengolah sumber daya timah dengan metode yang efektif dan ramah lingkungan yang terkait sintesis timah(II) sulfat dengan metode elektrolisis. Hasil penelitian menyimpulkan bahwa konsentrasi larutan elektrolit dan tegangan operasi sangat mempengaruhi sintesis timah(II) sulfat. Namun, variabel ini dibatasi oleh luas permukaan yang terbatas. Kondisi terbaik penelitian terjadi pada tegangan operasi 0,6V dan larutan elektrolit dengan konsentrasi 0,05 M.

“…Brines from Salar de Atacama (Chile) and Salar de hombre muerto (Argentina) have produced more than 60% high-grade lithium salt for the world market. Apart from mineral sources and brine, lithium is also found in oil fields, seawater, and geothermal brine [6,[11][12][13].…”

Indonesia is one of the countries in the world that has been utilizing geothermal as a renewable energy source to generate electricity. Depending on the geological setting, geothermal brine possesses critical elements worthwhile to extract. One of the critical elements is lithium which is interesting in being processed as raw material for the battery industries. This study thoroughly presented titanium oxide material for lithium recovery from artificial geothermal brine and the effect of Li/Ti mole ratio, temperature, and solution pH. The precursors were synthesized using TiO 2 and Li 2 CO 3 with several variations of the Li/Ti mole ratio mixed at room temperature for 10 min. The mixture of 20 g of raw materials was put into a 50 mL crucible and then calcined in a muffle furnace. The calcination temperature in the furnace was varied to 600, 750, and 900 °C for 4 h with a heating rate. of 7.55 °C/min. After the synthesis process, the precursor is reacted with acid (delithiation). Delithiation aims to release lithium ions from the host Li 2 TiO 3 (LTO) precursor and replace it with hydrogen ions through an ion exchange mechanism. The adsorption process lasted for 90 min, and the stirring speed was 350 rpm on a magnetic stirrer with temperature variations of 30, 40, and 60 °C and pH values of 4, 8, and 12. This study has shown that synthetic precursors synthesized based on titanium oxide can absorb lithium from brine sources. The maximum recovery obtained at pH 12 and a temperature of 30 °C was 72%, with the maximum adsorption capacity obtained was 3.55 mg Li/gr adsorbent. Shrinking Core Model (SCM) kinetics model provided the most fitted model to represent the kinetics model (R 2 = 0.9968), with the constants k f , Ds, and k, are 2.2360 × 10 −9 cm/s; 1.2211 × 10 –13 cm 2 /s; and 1.0467 × 10 –8 cm/s.

The need for lithium as a raw material for battery production in electric vehicles has triggered the growth of the lithium industry throughout the world, resulting in massive competition for the exploitation of lithium. Responding to these challenges, lithium recovery technology continues to be developed, one of which is membrane technology. This research focuses on the use of forward osmosis (FO) technology. The search for the best operating condition parameters for the process highlights a major concern. The condition parameters include temperature, draw solution concentration, and flow rate. The temperature varied from 30, 33, 36, 39 to 42 °C, the draw solution concentration varied from 1, 2 to 5 M, while the flow rate varied by 2, 3 and 4 L h −1 . The best conditions were obtained at a temperature of 42 °C, a concentration of 5 M draw solution, a flow rate of 4 L h −1 with a flux of 68.47 L m −2 h −1 , a normalized concentration ratio of 3.31, and an average solute rejection of 79.25%. Meanwhile, the most suitable osmotic pressure model to explain the phenomenon in the FO process is the Extended Pitzer.
