Recycling is a significant source for the supply of gold and has a pronounced effect on its price. The flotation method, which is more economical and more environmentally friendly than cyanide leaching, has been investigated for recycling gold and silver from jewellery slag. A jewellery slag sample containing 28.3 ppm Au and 42.0 ppm Ag was obtained from a refinery in Turkey. Flotation concentrate assaying 614.6 ppm Au and 511 ppm Ag was achieved with recoveries of 89.0% and 83.2%, respectively. On the other hand, 87.8% Au and 81.5% Ag extractions were obtained by cyanide leaching tests. Based on these results, flotation is suggested, considering its environmental and economic benefits.<\/jats:p>","DOI":"10.1177\/0734242x20931947","type":"journal-article","created":{"date-parts":[[2020,7,1]],"date-time":"2020-07-01T07:02:17Z","timestamp":1593586937000},"page":"233-241","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":9,"title":["Environmentally friendly process instead of cyanide leaching on recycling of gold and silver from jewellery scraps and wastes"],"prefix":"10.1177","volume":"39","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3873-6593","authenticated-orcid":false,"given":"\u015e Beste","family":"Ayd\u0131n","sequence":"first","affiliation":[{"name":"Mineral Processing Engineering Department, Faculty of Mines, Istanbul Technical University, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alim","family":"G\u00fcl","sequence":"additional","affiliation":[{"name":"Mineral Processing Engineering Department, Faculty of Mines, Istanbul Technical University, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2020,7,1]]},"reference":[{"key":"bibr1-0734242X20931947","unstructured":"Aerofloat 242 Promoter, MSDS No. 000038, Cytec Industries Inc, New Jersey, January 7, 2005."},{"key":"bibr2-0734242X20931947","unstructured":"Aerophine 3418A Promoter, MSDS No. 1787, Cytec Industries Inc, New Jersey, October 14, 1997."},{"key":"bibr3-0734242X20931947","first-page":"19","volume-title":"Natural hydrophobicity of native gold flakes and their flotation under different conditions","author":"Aksoy BS","year":"1989"},{"key":"bibr4-0734242X20931947","unstructured":"Bach L, N\u00f8rregaard RD, Hansen V, et al.
