Digestion\n consists of forming a slurry that is then treated to separate insoluble\n residues from the sodium aluminate liquor. The liquor is then\n crystallized and recycled back to green liquor after having been\n separated from the alumina trihydrate precipitated during\n crystallization. The process comprises a predesilication treatment during\n which the ground bauxite, before digestion, is brought into contact with\n an aqueous sodic solution that has a content of carbonates, sulphates and\n possibly chlorides which, expressed as a percentage related to the\n caustic concentration, has less than half of the corresponding impurities\n content of the spent liquor. Preferably, the pure caustic soda used to\n compensate for caustic soda losses in the Bayer circuit, previously\n injected just after evaporation, is now added in the aqueous sodic\n solution for the predesilication treatment.", "place": "", "country": "", "assignee": "Aluminium Pechiney\n(FR)", "issuingAuthority": "", "patentNumber": "7704471", "filingDate": "", "pages": "", "applicationNumber": "", "priorityNumbers": "", "issueDate": "April 27, 2010", "priorityDate": "", "references": "undefined undefined undefined undefined undefined undefined undefined undefined undefined", "legalStatus": "", "DOI": "", "citationKey": "", "url": "http://patft.uspto.gov/netacgi/nph-Parser?Sect2=PTO1&Sect2=HITOFF&p=1&u=%2Fnetahtml%2FPTO%2Fsearch-bool.html&r=1&f=G&l=50&d=PALL&RefSrch=yes&Query=PN%2F7704471", "accessDate": "2011-10-06T22:16:01Z", "shortTitle": "United States Patent", "language": "", "rights": "", "extra": "", "tags": [], "collections": [], "relations": {}, "dateAdded": "2011-10-06T22:16:01Z", "dateModified": "2011-10-06T22:16:01Z" } }, { "key": "SHQT332H", "version": 1, "library": { "type": "group", "id": 56499, "name": "TESC-AMR Lab", "links": { "alternate": { "href": "https://www.zotero.org/groups/tesc-amr_lab", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/56499/items/SHQT332H", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/tesc-amr_lab/items/SHQT332H", "type": "text/html" } }, "meta": { "createdByUser": { "id": 759907, "username": "Rhonas06", "name": "Nastassja Rhodes", "links": { "alternate": { "href": "https://www.zotero.org/rhonas06", "type": "text/html" } } }, "creatorSummary": "Peter", "parsedDate": "2009-08", "numChildren": 0 }, "data": { "key": "SHQT332H", "version": 1, "itemType": "journalArticle", "title": "The processing of high silica bauxites — Review of existing and potential processes", "creators": [ { "creatorType": "author", "firstName": "Smith", "lastName": "Peter" } ], "abstractNote": "", "publicationTitle": "Hydrometallurgy", "publisher": "", "place": "", "date": "August 2009", "volume": "98", "issue": "1-2", "section": "", "partNumber": "", "partTitle": "", "pages": "162-176", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "", "DOI": "doi: 10.1016/j.hydromet.2009.04.015", "citationKey": "", "url": "http://www.sciencedirect.com/science/article/pii/S0304386X09000863", "accessDate": "", "PMID": "", "PMCID": "", "ISSN": "0304-386X", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "", "libraryCatalog": "", "callNumber": "", "rights": "", "extra": "", "tags": [ { "tag": "Bauxite" }, { "tag": "Bayer" }, { "tag": "Desilication" }, { "tag": "Reactive silica" }, { "tag": "Review" }, { "tag": "Soda loss" } ], "collections": [], "relations": {}, "dateAdded": "2011-10-06T21:29:44Z", "dateModified": "2011-10-06T21:29:44Z" } } ]
