In this study, focusing on the extraction selectivity of EHO (2-ethylhexanal oxime), which extracts Cu, Ni and Pd from chloride solution, the mechanism and behavior of Cu2+ extraction with EHO from the leached solution of copper sulphide ores with ferric chloride solution and stripping of copper with water were investigated in order to clarify the possibility of an environmentally friendly hydrometallurgical process. The EHO extracts Cu2+ selectively from the chloride solution and the extraction reaction is a solvation type as follows ; Cu2+aq + 2Cl-aq + EHOorg＝CuCl2・2EHOorg The extractant does not extract other metal ions such as Zn2+, Fe2+ and Fe3+, which are the main impurities in the leached solution. It was also found that the extraction is an exothermic reaction of ΔH=-130kJ/mol and the stripping reaction is endothermic with the reaction heat of ΔH=43kJ/mol.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_9_publisher_34":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"資源・素材学会","subitem_publisher_language":"ja"}]},"item_9_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"資源・素材学会（http://www.jstage.jst.go.jp/browse/shigentosozai/_vols/-char/ja）"}]},"item_9_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN10062646","subitem_source_identifier_type":"NCID"}]},"item_9_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"09161740","subitem_source_identifier_type":"PISSN"}]},"item_9_version_type_17":{"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_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"芝田, 隼次","creatorNameLang":"ja"},{"creatorName":"Shibata, Junji","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"25717","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"70067742","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://nrid.nii.ac.jp/ja/nrid/1000070067742"}]},{"creatorNames":[{"creatorName":"間宮, 聡","creatorNameLang":"ja"},{"creatorName":"Mamiya, Satoshi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"25718","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"松本, 茂野","creatorNameLang":"ja"},{"creatorName":"Matsumoto, Shigeno","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"25719","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"山本, 秀樹","creatorNameLang":"ja"},{"creatorName":"Yamamoto, Hideki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"25720","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"30174808","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://nrid.nii.ac.jp/ja/nrid/1000030174808"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-05-23"}],"displaytype":"detail","filename":"KU-1100-19990000-08.pdf","filesize":[{"value":"341.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KU-1100-19990000-08.pdf","url":"https://kansai-u.repo.nii.ac.jp/record/11357/files/KU-1100-19990000-08.pdf"},"version_id":"753c7854-ffcb-4912-9b66-fbe9c259ba8b"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"溶媒抽出（Solvent Extraction）","subitem_subject_scheme":"Other"},{"subitem_subject":"硫化銅鉱（Copper Sulphide Ore）","subitem_subject_scheme":"Other"},{"subitem_subject":"塩化第2鉄（Ferric Chloride）","subitem_subject_scheme":"Other"},{"subitem_subject":"塩化物溶液（Chloride Solution）","subitem_subject_scheme":"Other"},{"subitem_subject":"2-エチルヘキサナールオキシム（2-ethylhexanal Oxime）","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"2-ethylhexanal oximeによる塩化物溶液からのCuの溶媒抽出","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"2-ethylhexanal oximeによる塩化物溶液からのCuの溶媒抽出","subitem_title_language":"ja"}]},"item_type_id":"9","owner":"1","path":["1594"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2011-11-22"},"publish_date":"2011-11-22","publish_status":"0","recid":"11357","relation_version_is_last":true,"title":["2-ethylhexanal oximeによる塩化物溶液からのCuの溶媒抽出"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-10-27T05:29:58.793961+00:00"}
