In this paper a new method of mechanical cable-bucket system combined with the drift of icebergs is discussed. In order to determine the amount of recoverable uranium, an iceberg of 1km in length and drifting at 1kt was chosen. Then, a 5-km loop with absorbent buckets attached at 3m intervals was hung over the iceberg. Assuming an absorption efficiency is 30% and a desorption efficiency 90%, the amount of uranium produced by this recovery process was estimated to be 77t a year.","subitem_description_type":"Other"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA00733561","subitem_source_identifier_type":"NCID"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Department of Mineral Science and Technology, Faculty of Engineering, Kyoto University"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1984-09-01"}],"displaytype":"detail","filename":"KJ00000012285.pdf","filesize":[{"value":"191.3 kB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"url":"https://nipr.repo.nii.ac.jp/record/1653/files/KJ00000012285.pdf"},"version_id":"66092eae-201b-4dfd-b1c9-b38fda87da63"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"An idea on extraction of uranium from seawater using the drift of icebergs","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"An idea on extraction of uranium from seawater using the drift of icebergs","subitem_title_language":"en"}]},"item_type_id":"1","owner":"4","path":["387"],"pubdate":{"attribute_name":"公開日","attribute_value":"1984-09-01"},"publish_date":"1984-09-01","publish_status":"0","recid":"1653","relation_version_is_last":true,"title":["An idea on extraction of uranium from seawater using the drift of icebergs"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T13:50:27.915157+00:00"}
