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.

Electrolytic Gold Deposition on Dodecanethiol-Modified Gold Films
Langmuir, 2009The electrochemical nucleation and growth of Au from a Au sulfite electrolyte onto dodecanethiol-modified Au surfaces is investigated by a combination of microscopy and chronoamperometry methods. The self-assembled dodecanethiol monolayers are continuous but exhibit defects in correspondence of the Au grain boundaries and on top of Au terraces ...

Studies of fresh carbonate host rocks and unoxidized gold ores of the Carlin mine indicate that gold, quartz, barite, pyrite, and other sulfides were introduced into the Roberts Mountains Formation by acid hydrothermal solutions. Laboratory investigations on the carbonaceous materials in the host rocks and ores and studies of reactions between ...

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 ...

The Mokrsko Gold Deposit—the Largest Gold Deposit in the Bohemian Massif, Czechoslovakia
1989Abstract The recently discovered Mokrsko deposit represents the largest gold deposit in the Bohemian massif. The deposit occurs in upper Proterozoic volcano-sedimentary rocks of the Jilove belt (640-700? Ma) and in granodiorite of Hercynian age (320-360 Ma).

Placer gold deposits are abundant in Mongolia and form through endogenic and exogenic processes. Deposits are classified into four major genetic types: (1) eluvial-weathering zone, (2) deluvial, (3) proluvial, and (4) alluvial. The most economic deposits are often sourced from upper Cretaceous rocks and formed in late Cenozoic alluvial fans (Liskun and

Gold deposits rich in bismuth minerals: An important type of gold deposits
2005Several gold deposits, both in China and abroad, are drawing attention because of their abundant bismuth minerals. Comparative studies on some of them indicate that certain characteristics can aid in identifying standards and exploration criteria of the type of gold deposits. Firstly, the lode gold ore bodies are structurally controlled.
