Herein, Bayan Obo tailings and coal gangue were used as complementary precursors to synthesize magnetic NaA zeolite through alkali fusion followed by low-temperature hydrothermal crystallization. The time-dependent phase evolution and framework assembly were investigated by X-ray diffraction, Raman spectroscopy, and solid-state 29Si\/27Al MAS NMR. The 6-h product was selected because it balanced LTA crystallinity, cubic morphology, and magnetic separability. Rietveld refinement of the 6-h product gave reliable fitting parameters, with Rwp = 1.92%, Rp = 1.34%, Rexp = 1.23%, and GOF = 1.56; VSM analysis showed a saturation magnetization of 4.38 emu g\u20131. Spectroscopic results suggest the progressive ordering of Si\/Al = 1 aluminosilicate units and the development of \u03b2-cage- and \u03b1-cage-related LTA framework environments during NaA crystallization. The obtained magnetic zeolite was evaluated for the adsorption of Ni2+, Cu2+, and Zn2+ and for selective ion uptake from simulated and real NdFeB electroplating wastewater. Adsorption equilibrium was reached within 60 min, and Cu2+ showed the highest uptake among the tested divalent metals. In simulated Ni-rich systems, Nd3+ and Pr3+ showed preferential uptake over Ni2+, and the apparent distribution-coefficient order was Pr3+ &amp;gt; Nd3+ &amp;gt; Ni2+. This selectivity was further verified using real NdFeB nickel-plating wastewater containing 10.87 mg L\u20131 Pr, 131.57 mg L\u20131 Nd, and 959.44 mg L\u20131 Ni. At an adsorbent dosage of 15 g L\u20131, the removal efficiencies of Pr and Nd reached approximately 99% and 94%, respectively, while Ni co-removal remained low. Regeneration tests showed acceptable reusability after three adsorption-desorption cycles, and toxicity leaching tests indicated low release levels of hazardous elements. This work provides a dual-solid-waste route for preparing magnetic NaA zeolite and demonstrates its potential for selective rare-earth enrichment from Ni-rich NdFeB electroplating wastewater.<\/jats:p>","DOI":"10.1021\/acsomega.6c05109","type":"journal-article","created":{"date-parts":[[2026,9,11]],"date-time":"2026-09-11T14:01:56Z","timestamp":1789135316000},"page":"55888-55902","source":"Crossref","is-referenced-by-count":0,"title":["Crystallization\nPathway of Magnetic NaA Zeolite from\nBayan Obo Tailings and Coal Gangue for Selective Ion Uptake from NdFeB\nElectroplating Effluents"],"prefix":"10.1021","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0009-0009-7274-968X","authenticated-orcid":true,"given":"Pengyu","family":"Wang","sequence":"first","affiliation":[{"name":"Inner Mongolia University of Science and Technology , , ,","place":["Baotou, China, 014010"]},{"name":"Ministry of Education , , ,","place":["Baotou, China, 014010"]},{"name":"Intellectual Property Protection Center of Inner Mongolia Autonomous Region , ,","place":["Hohhot, China, 010030"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ke","family":"Wang","sequence":"additional","affiliation":[{"name":"Baotou Rare Earth New Material Technology R & D Center , ,","place":["Baotou, China, 014060"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8236-438X","authenticated-orcid":true,"given":"Yuxin","family":"Chen","sequence":"additional","affiliation":[{"name":"Inner Mongolia University of Science and Technology , , ,","place":["Baotou, China, 014010"]},{"name":"Ministry of Education , , ,","place":["Baotou, China, 014010"]},{"name":"Inner Mongolia University of Science and Technology , , ,","place":["Baotou, China, 014010"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kexuan","family":"Shen","sequence":"additional","affiliation":[{"name":"Inner Mongolia University of Science and Technology , , ,","place":["Baotou, China, 014010"]},{"name":"Ministry of Education , , ,","place":["Baotou, China, 014010"]},{"name":"Inner Mongolia University of Science and Technology , , ,","place":["Baotou, China, 014010"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jun","family":"Peng","sequence":"additional","affiliation":[{"name":"Inner Mongolia University of Science and Technology , , ,","place":["Baotou, China, 014010"]},{"name":"Ministry of Education , , ,","place":["Baotou, China, 014010"]},{"name":"Inner Mongolia University of Science and Technology , , ,","place":["Baotou, China, 014010"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhanfeng","family":"Yang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Baiyunobo Rare Earth Resource Researches and Comprehensive Utilization , ,","place":["Baotou, China, 014010"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shengli","family":"An","sequence":"additional","affiliation":[{"name":"Inner Mongolia University of Science and Technology , , ,","place":["Baotou, China, 014010"]},{"name":"Ministry of Education , , ,","place":["Baotou, China, 014010"]},{"name":"Inner Mongolia University of Science and Technology , , ,","place":["Baotou, China, 014010"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2026,9,11]]},"reference":[{"key":"2026092210585301000_cit1","doi-asserted-by":"publisher","first-page":"128957","DOI":"10.1016\/j.seppur.2024.128957","article-title":"Zeolite Preparation\nfrom Industrial Solid Waste: Current Status,\nApplications, and Prospects.
