The ankerite was found to contain the following minerals, ankerite, calcite, dolomite synchisite, barite from X-ray and EPMA studies. γ-ray spectrometry proved that this ore is also impotant as uranium and thorium resources because of their contents of 0.01% and 1.2%, respectively. The radioactive problems from radium must be discussed. The ore can be easily dissolved in concentrate HC1 solution, and selective leaching by controlling pH and reaction time and selective precipitation by adding sodium hydroxide and ammonium oxalate are possible. Finally, lanthan and cerium solution of 99% content with 88% recovery was obtained which was available for crude rare earth chlorides.","subitem_description_type":"Abstract"}]},"item_4_description_41":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"紀要類(bulletin)","subitem_description_type":"Other"}]},"item_4_description_66":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"799241 bytes","subitem_description_type":"Other"}]},"item_4_full_name_2":{"attribute_name":"著者(ヨミ)","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"124890","nameIdentifierScheme":"WEKO"}],"names":[{"name":"SATO, Nobuaki"}]},{"nameIdentifiers":[{"nameIdentifier":"124892","nameIdentifierScheme":"WEKO"}],"names":[{"name":"NANJO, Michio"}]}]},"item_4_publisher_34":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東北大學選鉱製錬研究所"}]},"item_4_radio_69":{"attribute_name":"公開範囲","attribute_value_mlt":[{"subitem_radio_item":"学外"}]},"item_4_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0040876X","subitem_source_identifier_type":"ISSN"}]},"item_4_source_id_9":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00168425","subitem_source_identifier_type":"NCID"}]},"item_4_version_type_16":{"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":"佐藤, 修彰"}],"nameIdentifiers":[{"nameIdentifier":"124888","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"BAZAN, Ana Lucia C."}],"nameIdentifiers":[{"nameIdentifier":"124891","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"南條, 道夫"}],"nameIdentifiers":[{"nameIdentifier":"124889","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":"2017-02-20"}],"displaytype":"detail","filename":"KJ00000135475.pdf","filesize":[{"value":"799.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00000135475.pdf","url":"https://tohoku.repo.nii.ac.jp/record/50755/files/KJ00000135475.pdf"},"version_id":"b90ec962-648c-4338-893c-19029b6990ba"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"rare earth","subitem_subject_scheme":"Other"},{"subitem_subject":"synchisite","subitem_subject_scheme":"Other"},{"subitem_subject":"ankerite","subitem_subject_scheme":"Other"},{"subitem_subject":"calcite","subitem_subject_scheme":"Other"},{"subitem_subject":"carbonatite","subitem_subject_scheme":"Other"},{"subitem_subject":"uranium","subitem_subject_scheme":"Other"},{"subitem_subject":"thorium","subitem_subject_scheme":"Other"},{"subitem_subject":"metallurgy","subitem_subject_scheme":"Other"},{"subitem_subject":"Vale do Ribeira","subitem_subject_scheme":"Other"},{"subitem_subject":"Brazil","subitem_subject_scheme":"Other"}]},"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":"<報文>レアメタル資源に関する研究 (IV) ブラジル,Vale do Ribeira産カーボナタイトのキャラクタリゼーションと処理法の検討","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"<報文>レアメタル資源に関する研究 (IV) ブラジル,Vale do Ribeira産カーボナタイトのキャラクタリゼーションと処理法の検討"}]},"item_type_id":"4","owner":"3","path":["292"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-05-02"},"publish_date":"2008-05-02","publish_status":"0","recid":"50755","relation_version_is_last":true,"title":["<報文>レアメタル資源に関する研究 (IV) ブラジル,Vale do Ribeira産カーボナタイトのキャラクタリゼーションと処理法の検討"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-07-27T16:55:44.071311+00:00"}
