Conventional cyanidation, however, suffers from extreme toxicity and environmental hazards that make it unsustainable. We report a nontoxic synergistic leaching system based on oxalic acid and cyano\u2010functionalized branched quaternary ammonium salts. Under mild conditions, this one\u2010step method enables efficient and selective leaching of lattice\u2010confined silver from polymetallic manganese\u2013silver ore, with recoveries exceeding 90%. Kinetic studies reveal a two\u2011stage process, with an initial rapid dissolution of exposed manganese oxides releasing silver followed by a slower breakdown of the iron matrix to liberate encapsulated minerals. The core breakthrough is the discovery that AgCl combines with chloride anions from the quaternary ammonium salt to form a unique inorganic helical chain structure. The stability of this helical assembly is attributed to an ordered CH\u2026Cl\n                    <jats:sup>\u2212<\/jats:sup>\n                    H\u2010bonded network. Spectroscopic characterization and theoretical calculations confirm that this network undergoes an energetically favorable reconstruction that overcomes the high lattice energy of AgCl. This finding demonstrates that the cooperative effect of weak H\u2010bonds can dissociate covalently stabilized solids. Our study thus provides an innovative strategy for sustainable silver metallurgy and introduces a new paradigm of H\u2010bond\u2010directed metallurgical design.\n                  <\/jats:p>","DOI":"10.1002\/anie.202514318","type":"journal-article","created":{"date-parts":[[2025,9,16]],"date-time":"2025-09-16T03:56:46Z","timestamp":1757995006000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["One\u2010Step Silver Leaching from Manganese\u2013Silver Ore Enabled by Hydrogen\u2010Bonded Network Formation"],"prefix":"10.1002","volume":"64","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1916-2996","authenticated-orcid":false,"given":"Zhiyuan","family":"Zeng","sequence":"first","affiliation":[{"name":"Institute of Nuclear and New Energy Technology Tsinghua University  Haidian District Beijing 100084 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bin","family":"Li","sequence":"additional","affiliation":[{"name":"Institute of Nuclear and New Energy Technology Tsinghua University  Haidian District Beijing 100084 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuntao","family":"Zheng","sequence":"additional","affiliation":[{"name":"Institute of Nuclear and New Energy Technology Tsinghua University  Haidian District Beijing 100084 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiehui","family":"Hu","sequence":"additional","affiliation":[{"name":"Institute of Nuclear and New Energy Technology Tsinghua University  Haidian District Beijing 100084 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peilun","family":"Li","sequence":"additional","affiliation":[{"name":"Institute of Resources Utilization and Rare Earth Development Guangdong Academy of Sciences  Guangzhou Guangdong 510651 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dianwen","family":"Liu","sequence":"additional","affiliation":[{"name":"College of Land and Resources Engineering Kunming University of Science and Technology  Kunming Yunnan 650093 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6765-9251","authenticated-orcid":false,"given":"Shengming","family":"Xu","sequence":"additional","affiliation":[{"name":"Institute of Nuclear and New Energy Technology Tsinghua University  Haidian District Beijing 100084 China"},{"name":"Southwest United Graduate School  No.298, Yieryi Street Kunming Yunnan 650092 China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,9,15]]},"reference":[{"key":"e_1_2_8_1_1","first-page":"3097","volume":"5","author":"Fan Z.","year":"2016","journal-title":"Chem.
