The reduced pellets are also extracted with bromin -methanol solution for research the reducibility.Ni and Co extractions with sulphuric acid to the reduced pellets in which include 7.5 % sulphur are improved 1 30/0 in Ni and 70/0 in Co as compared with to no addition of sulphur.In case of no addition of sulphur, the reduced nickel elements present as Ni-Fe alloys such as tetrataenite and josephinite . Forsterites are almost recrystallized as forsterite ferroan . On the other hand, enstatites do not contain iron element almost. With increase of addition of sulphur , the peak intensities of tetrataenite and josephinite decrease rapidly and peak intensities of metallic iron increase remarkablely.Peaks of NiS, CoS and FeS appear at 1.0%, 2.5%, and 1.0% respectively. These NiS, CoS and FeS are dissolved easily with heated sulphuric acid.Therefore, it is understood that an additive sulphur of more than 5% promotes recrystallization of forsterite ferroan and reducibility of goethite.As a result, substitution between Ni(Co) and Fe is promoted and the formation of NiS and CoS are also increased . Addition of sulphur depresses the rising rate of PH during oxidation period with 03 and decreases the extraction of Mg, and oxidation time becomes longer. As a result, Fe^<2+> and Mn^<2+> are oxidized, sedimentated and removed effectively.","subitem_description_type":"Abstract"}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.57375/00000504","subitem_identifier_reg_type":"JaLC"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"福井工業大学"}]},"item_10002_relation_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"TF00008963","subitem_relation_type_select":"NCID"}}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2868571","subitem_source_identifier_type":"ISSN"}]},"item_10002_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"光冨, 勝義"}],"nameIdentifiers":[{"nameIdentifier":"10224","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"押田, 稔"}],"nameIdentifiers":[{"nameIdentifier":"10225","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Mitsutomi, Katsuyoshi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"10226","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Oshida, Minoru","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"10227","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2023-04-12"}],"displaytype":"detail","filename":"KJ00000201871.pdf","filesize":[{"value":"521.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00000201871.pdf","url":"https://fut.repo.nii.ac.jp/record/510/files/KJ00000201871.pdf"},"version_id":"085f96a8-9f21-4ef9-b667-dc799a5f3409"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"褐鉄鉱質ニッケルラテライト鉱に対する硫黄硫化剤の諸効果について","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"褐鉄鉱質ニッケルラテライト鉱に対する硫黄硫化剤の諸効果について"},{"subitem_title":"On Effects of Sulfurizing Reagent with Native Sulphur to the Limonitic Nickel Laterite Ore","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"2","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2009-04-10"},"publish_date":"2009-04-10","publish_status":"0","recid":"510","relation_version_is_last":true,"title":["褐鉄鉱質ニッケルラテライト鉱に対する硫黄硫化剤の諸効果について"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-06-20T14:30:58.249074+00:00"}
