A uniform, bright, high purity gold deposit can be obtained by using a dip gold plating process, characterized by high bath stability. The properties of the deposit have been examined by SEM, SRD and XPS.

Laser-induced deposition of gold
AIP Conference Proceedings, 1986AbstractThe laser-induced, vapor-phase deposition of gold metal from dimethyl-(2,4-pentanedionato) gold (III) and two fluorinated derivatives was examined by both photopyrolytic (LCVD) and photochemical modes of decomposition. High purity gold deposits are formed by LCVD with the rates of deposition being extremely vapor pressure dependent and thus ...

Summary It is shown that in the case of Au deposition from CN− solution slow surface area changes take place which can be observed by potentiostatic pulse and a.c. impedance methods. The mechanism of incorporation of CN into the Au deposit is briefly discussed.

The fast growth of global gold prices over the past two decades has boosted interest in the development of large-tonnage deposits with low metal contents. If this trend continues, zones of fine sulfidation may be considered potential and practically inexhaustible deposits of noble metals. The authors have distinguished and briefly characterized several

Lode gold deposits are one of the most characteristic features of Archaean greenstone belts within granitoid-greenstone terranes, with major deposits situated in most major cratonic areas (e.g. Australia, Brazil, Canada, India, South Africa, Zimbabwe: Foster, 1984; Macdonald, 1986; Ho and Groves, 1987).
