Strong acidic wastewater (pH3.5) from pithead of the mine contains high concentration of heavy metals. In this mine, neutralizing coagulation treatment is going on by slaked lime (calcium hydroxides: Ca (OH)_2). Core samples were collected at disposal pond to which the treated wastewater flows. The core samples were divided into 44 layers based on the color variation. The mineralogical and chemical compositions of each layer were analyzed by an X-ray powder diffractometer (XRD), an energy dispersive X-ray fluorescence analyzer (ED-XRF) and a NCS elemental analyzer. The upper parts are rich in brown colored layers, whereas discolored are the deeper parts. The color variation is relevant to Fe concentration. Brown colored core sections are composed of abundant hydrous ferric oxides with heavy metals, such as Cu, Zn, and Cd. On the other hand, S concentration gradually increases with depth. XRD data indicated that calcite decreases with increasing depth, and ettringite is produced at the deeper parts. Cd concentration shows similar vertical profile to those of calcite and ettringite. The results revealed that hydrous ferric oxides, calcite and ettringite are formed on deposition, whereby incorporating the heavy metals.","subitem_description_type":"Abstract"}]},"item_4_description_5":{"attribute_name":"提供者所属","attribute_value_mlt":[{"subitem_description":"金沢大学理工研究域地球社会基盤学系","subitem_description_type":"Other"}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00061676","subitem_identifier_reg_type":"JaLC"}]},"item_4_publisher_17":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"地学団体研究会 The Association for the Geological Collaboration in Japan"}]},"item_4_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.15080/agcjchikyukagaku.54.5_328","subitem_relation_type_select":"DOI"}}]},"item_4_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://www.jstage.jst.go.jp/browse/agcjchikyukagaku/-char/ja"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.jstage.jst.go.jp/browse/agcjchikyukagaku/-char/ja","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"http://www.chidanken.jp/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.chidanken.jp/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://www.chidanken.jp/08_1.html"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.chidanken.jp/08_1.html","subitem_relation_type_select":"URI"}}]},"item_4_rights_23":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright © 地学団体研究会 The Association for the Geological Collaboration in Japan"}]},"item_4_source_id_11":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AN00141269","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0366-6611","subitem_source_identifier_type":"ISSN"},{"subitem_source_identifier":"2189-7212","subitem_source_identifier_type":"ISSN"}]},"item_4_version_type_25":{"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, 大介"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"田崎, 和江"}],"nameIdentifiers":[{},{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2021-07-26"}],"displaytype":"detail","filename":"SC-PR-TAZAKI-K-328.pdf","filesize":[{"value":"1.5 MB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"SC-PR-TAZAKI-K-328.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/55401/files/SC-PR-TAZAKI-K-328.pdf"},"version_id":"ea5720ca-1065-4cca-b758-18e1a91b9d86"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"鉱山廃水の消石灰処理と重金属の堆積形態","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"鉱山廃水の消石灰処理と重金属の堆積形態"},{"subitem_title":"Calcification treatment of mine drainage and depositional formula of heavy metals","subitem_title_language":"en"}]},"item_type_id":"4","owner":"18","path":["937"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-07-26"},"publish_date":"2021-07-26","publish_status":"0","recid":"55401","relation_version_is_last":true,"title":["鉱山廃水の消石灰処理と重金属の堆積形態"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2023-07-27T15:10:21.310825+00:00"}
