Efficient lithium recovery, especially from water sources, is essential due to the growing demand need for LIB recycling. Adsorption technology is effective for this purpose, but traditional powder adsorbents present operational challenges. To overcome this, 3D printing allows for the preparation of solid monolith adsorbents with improved mechanical stability and reusability. In this work, a polyamide-lithium titanium oxide composite (PA2200-Li₂TiO₃) was 3D-printed using selective laser sintering technology. The composite was characterized using SEM-EDS, TEM, XRD, Raman spectroscopy, TGA and XPS. The adsorbent exhibited up to 87 % lithium adsorption efficiency at a concentration of 20 mg/L and showed high selectivity for lithium over sodium (Li/Na ≈ 37.4) and potassium (Li/K ≈ 60.5). A mechanism involving Li⁺ ion adsorption and transport through Li₂TiO₃’s structural channels has been proposed, with dynamic simulations suggesting that lithium ions preferentially diffuse through these channels due to their geometric and energetic configuration. Thermodynamic studies confirmed an endothermic adsorption process with enhanced performance at higher temperatures. Regeneration tests demonstrated only a 7 % reduction in adsorption efficiency after three cycles, indicating structural stability and the potential for scalable application in lithium recovery processes.</div></div>","PeriodicalId":18594,"journal":{"name":"Minerals Engineering","volume":"231 ","pages":"Article 109470"},"PeriodicalIF":4.9,"publicationDate":"2025-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144168781","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The bulk of the ore was occupied by clay and silicate minerals including mica, quartz, K-silicates, and Na-silicates. Subsequently, magnetic separation tests were conducted on the ore using a wet high intensity magnetic separator (WHIMS), where the relative effects of applied magnetic field intensity, matrix type, feed mass, feed desliming, and concentrate regrinding on REE minerals recovery were investigated. Experimental results showed that increasing magnetic field intensity and using fine expanded metal matrix enhanced REE minerals recovery, although concentrate grade was compromised. Additionally, different magnetic separation flowsheets employing regrinding and desliming stages were tested. The highest concentrate grade of 9.12 % total rare earth oxide (TREO) was achieved when the deslimed feed was processed at 1.7 T with the WHIMS fitted with the medium expanded metal matrix mesh, where 86 % REE recovery was observed. A beneficiation process flow sheet for recovering and upgrading REE minerals in the low-grade saprolite ore has been proposed, which recovered 74 % REE assaying a concentrate grade of 9.12% TREO . It was observed that the recovery of mica, entrainment recovery of liberated and unliberated silicate minerals and the presence of bastnäsite/REE-silicates intergrowths limited the extent of TREO upgrade that could be achieved although recoveries were high.

This paper conducts a comprehensive analysis of the industry requirements for high-purity quartz sand used in crucibles from multiple aspects, including purity, inclusions, particle size, and micro-morphology. Purity affects crucible thermal stability and optical properties; Inclusions reduce transparency and affect the thickness of transparent layer and bubble content; Good homogeneity is required in terms of particle size and morphology.

This study analyzed the direct and background environmental footprints of recycling a mixed blend of LIBs and recovering lithium (Li) using a hybrid approach. This process combined two segments: pyrometallurgy and hydrometallurgy. Pyrometallurgy included the incineration process to liberate constituents, the smelting section to form Li-bearing slag, and the chlorination roasting process for chemically assisted transformation. This was followed by the hydrometallurgy segment, where Li was recovered. A specialized environmental life cycle assessment method was applied to evaluate the environmental burden of each section.

Lacking proper treatment, the resulting red mud poses significant ecological threats. Converting iron-containing phases, such as goethite and hematite, to magnetite during leaching is essential for improving alumina extraction and recovering iron resources. This study addresses this challenge by leveraging the reductive thermal properties of starch within an alkaline thermal environment to facilitate the transformation and recovery of iron oxides. We systematically investigated the effects of various process parameters, and analyzed hematite transformation using X-ray diffraction (XRD), X-ray fluorescence (XRF), scanning electron microscopy (SEM), and chemical analysis. The surface properties were characterized through zeta potential, wettability, and solvation tendency assessments. Our results indicate that increased temperature, mass ratio of starch to hematite(S/H), and sodium oxide concentration significantly promote hematite transformation. During simulated Bayer leaching at 260 °C, with 240 g/L sodium oxide, a mother liquor molecular ratio of 3.1, a liquid-to-solid ratio of 4, and a starch to iron oxide mass ratio of 0.5, we achieved an iron oxide reduction rate of 96.91 % after 60 min. Magnetite and de-silicated product (DSP) exhibit distinct surface properties compared to hematite, which facilitates the aggregation, growth, and separation of hematite from DSP. Furthermore, the direct addition of starch to the high-temperature Bayer leaching process of high-iron bauxite enhances the transformation and separation of iron phases while reducing sodium oxide content in red mud.

To address this knowledge gap, column reactor systems simulating in-situ leaching conditions were utilized to conduct comparative leaching experiments under atmospheric (0 kPa) and negative pressure (−60 kPa) conditions. Comprehensive analyses of solution ion migration, rare earth leaching dynamics, and leaching agent retention yielded the following conclusions: (1) Negative pressure significantly enhanced hydraulic efficiency, achieving 5.7-fold and 6.8-fold increases in infiltration and effluent discharge rates, respectively, while reducing the leaching cycle to 26 % of the atmospheric baseline.

(3) Reduced leaching agent retention was observed under negative pressure, with residual readily desorbable Mg²⁺ content decreasing by 15.9 % relative to atmospheric conditions.
