In this research work, focus was made on recovery of copper from underexplored mineral resource of mine tailing and complex carbonaceous sulphide ore. These resources are potential reserve to metal production inventory that is faced with declining ore grade. The preliminary studies of copper recovery indicated that mineralogical composition was one of the main components to consider for the processing method employed. Therefore, it is essential to develop effective method for specific mineral resources of copper. The process conditions for flotation and high-pressure leaching were tested and optimized to recover copper from the two mineral resources. Hence, the two main chapters in this PhD thesis discussed the process development for each mineral resource and conclusion were drawn.","subitem_description_type":"Other"}]},"item_10006_dissertation_number_42":{"attribute_name":"学位授与番号","attribute_value_mlt":[{"subitem_dissertationnumber":"甲第1281号"}]},"item_10006_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.20569/00003809","subitem_identifier_reg_type":"JaLC"}]},"item_10006_publisher_28":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"秋田大学"}]},"item_10006_version_type_35":{"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":"REFILWE, SANDRA MAGWANENG"}],"nameIdentifiers":[{"nameIdentifier":"15127","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":"2019-06-18"}],"displaytype":"detail","filename":"kouhakuyoushikou1281.pdf","filesize":[{"value":"188.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"内容要旨及び審査結果要旨","url":"https://air.repo.nii.ac.jp/record/3450/files/kouhakuyoushikou1281.pdf"},"version_id":"196e8533-a601-4d4d-a673-16aea5acad2c"},{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-06-18"}],"displaytype":"detail","filename":"kouhakukou1281.pdf","filesize":[{"value":"5.9 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"本文","url":"https://air.repo.nii.ac.jp/record/3450/files/kouhakukou1281.pdf"},"version_id":"6d810d5c-5da1-4fac-affc-1f0b856cd224"}]},"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":"doctoral thesis","resourceuri":"http://purl.org/coar/resource_type/c_db06"}]},"item_title":"Recovery of Copper from Mine Tailing and Complex Carbonaceous Sulfide Ore by Flotation and High-Pressure Leaching","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Recovery of Copper from Mine Tailing and Complex Carbonaceous Sulfide Ore by Flotation and High-Pressure Leaching"}]},"item_type_id":"10006","owner":"3","path":["1197"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-06-18"},"publish_date":"2019-06-18","publish_status":"0","recid":"3450","relation_version_is_last":true,"title":["Recovery of Copper from Mine Tailing and Complex Carbonaceous Sulfide Ore by Flotation and High-Pressure Leaching"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-07-25T10:51:52.375913+00:00"}
