The phase compositions of metal, matte, and slag were determined using electron probe microanalysis (EPMA). The effects of reduction time and amount of reductant were investigated. The distribution of elements between metal\/matte and slag was ascertained based on the elemental concentrations determined by EPMA. It was found that copper concentration in slag can be effectively decreased to approximately 0.4\u20130.6\u00a0wt% within 5\u00a0min by coke and biochar. Copper and nickel can also be successfully recovered into the copper alloy phase once settling has been accomplished.<\/jats:p>\n                <jats:p><jats:bold>Graphical Abstract<\/jats:bold><\/jats:p>","DOI":"10.1007\/s40831-024-00793-7","type":"journal-article","created":{"date-parts":[[2024,2,29]],"date-time":"2024-02-29T17:02:42Z","timestamp":1709226162000},"page":"360-374","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Recovery of Metals from Copper Smelting Slag Using Coke and Biochar"],"prefix":"10.1007","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0544-4359","authenticated-orcid":false,"given":"Min","family":"Chen","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8752-4776","authenticated-orcid":false,"given":"Dmitry","family":"Sukhomlinov","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4054-952X","authenticated-orcid":false,"given":"Pekka","family":"Taskinen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7174-008X","authenticated-orcid":false,"given":"Joseph","family":"Hamuyuni","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Radoslaw M.","family":"Michallik","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6722-0700","authenticated-orcid":false,"given":"Mari","family":"Lindgren","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0582-7181","authenticated-orcid":false,"given":"Ari","family":"Jokilaakso","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2024,2,29]]},"reference":[{"key":"793_CR1","doi-asserted-by":"publisher","first-page":"468","DOI":"10.1007\/s40831-023-00683-4","volume":"9","author":"E Klaffenbach","year":"2023","unstructured":"Klaffenbach E, Montenegro V, Guo M, Blanpain B (2023) Sustainable and comprehensive utilization of copper slag: a review and critical analysis.
