Biorecovery of Gold from Jewellery Wastes by Escherichia Coli and Biomanufacture of Active Au-Nanomaterial

Autor: Lynne E. Macaskie, Kevin Deplanche, Gary Anthony Attard

Publikováno v: Advanced Materials Research. :647-650

Microbial reduction of Au(III) from HAuCl4 was demonstrated. Escherichia coli and Desulfovibrio desulfuricans reduced 1 mM Au(III) in 60 and 120 min at pH 6.9 and 2.3 respectively. TEM and elemental analysis showed the formation of Au(0) nanoparticle

Publikováno v: Metalurgija, Vol 53, Iss 4, Pp 605-608 (2014)

In the presented study the flotation process has been proposed as a method of enrichment of silver-bearing jewellery waste. This method, traditionally used for the enrichment of non-ferrous metal ores, is based on differences in wettability between i
