Patent number: 10214796Abstract: Methods for recovering gold from gold-bearing materials are provided. The methods rely upon on the self-assembly of KAuBr4 and ?-cyclodextrin (?-CD) in aqueous solution to form a co-precipitate, a 1:2 complex, KAuBr4•(?-CD)2 (“?•Br”), either alone or in an extended {[K(OH2)6][AuBr4]?(?-CD)2}n chain superstructure (FIG. 1). The co-precipitation of ?•Br is selective for gold, even in the presence of other metals, including other square-planar noble metals. The method enables one to isolate gold from gold-bearing materials from diverse sources, as further described.Type: GrantFiled: July 25, 2016Date of Patent: February 26, 2019Assignee: Northwestern UniversityInventors: J.
