Editor's Note: After publishing an article by gold-plating expert and occasional guest writer, Calla Gold, we received several inquiries. Calla was kind enough to answer the questions below. The original article: How Gold Plating is Done, Step by Step 1. QUESTION "I have a very collectible and valuable vintage bracelet made of base …
The purpose of this thread is to begin to consolidate the vast amount of questions and answers related to the Acid Peroxide (aka AP) recovery process. First and foremost, the name for the process, Acid Peroxide is a misnomer as the active ingredient is actually copper II chloride (CuCl2), so it...
Recycling and recovery of spent gold electroplating solutions present a unique, economically viable, and environmentally friendly alternative. By reclaiming the …
Not much to say about the functionality of memory sticks, though one may seriously consider doing a test for working units, working units may be sold at a higher price that will far exceed the precious metals (PM's) …
I suspect that you are using too high a voltage when plating out the gold from your drag-out tank. I try to keep the voltage between 4-5 Volts on my gold recovery unit. We have used the same 316 SS anodes for our gold bath for many years with almost no deterioration. We always transfer our drag-out to a separate treatment tank for gold …
Additionally, the amount of gold in a SIM card is typically minimal and not worth the potential risks of burning circuit boards. However, there are alternative methods available for gold recovery that you may wish to consider. What electronics contain the most gold? Electronics that contain the most gold are typically used in large quantities ...
Gold plating helps in ensuring efficient signal transmission and long-term reliability, which are essential for vehicle safety and functionality. Gold's unique properties make it suitable for high-performance parts that must endure extreme conditions. This extends the lifespan of the components and enhances their performance.
A series of Au x /TiO 2 nanoparticles (NPs) with different gold loadings (x = 0.1-1.0 wt%) was synthesized by the photodeposition and then employed as photocatalysts to recover precious component from the industrial gold-cyanide plating wastewater. Effects of Au loading, catalyst dosage and types of hole scavenger on the photocatalytic gold …
Editor's Note: We received an inquiry regarding our article, How Gold Plating is Done, Step by Step by Calla Gold, a Santa Barbara jeweler specializing in custom jewelry design and jewelry repair. Here's her answer: Reader's Questions: How do I recover microscopic gold from plating solution? Is there much gold left in …
A new method for recovering high-purity gold from discarded electronics is paying back US$50 for every dollar spent, according to Swiss researchers – who found their all-important gold-filtering ...
You can measure the content of all gold and precious metals, as well as determine the presence and concentration of other trace, alloying elements, and dangerous heavy elements, which could impact …
for the recovery of elemental mercury (Hgº), a grey-silver metal which is liquid at room temperature. This type of mercury is used by artisanal miners to make an amalgam with gold and thus extract the maximum possible amount of gold. 3.1. General description of the copper plate technique
Gold plated jewelry can be restored to some extent, but it depends on the thickness of the gold plating and the condition of the underlying metal. If the gold plating is worn or tarnished, it can be re-plated by a professional jeweler. However, if the plating is very thin or has completely worn off in some areas, restoration may not be possible.
A rapid photocatalytic gold recovery from the industrial cyanide-based gold plating wastewater was carried out via TiO2/WO3 nanocomposites synthesized by hydrothermal method.
And I am approaching my first attempt at recovering all the gold plating from the various parts I've got. I was getting ready to get my hands on some HCl, nitric acid (or bleach), H2O2, stannous choride, SMB and pH testing paper for recovery.
Gold plating involves depositing a thin layer of gold onto a base metal through a process called electroplating. Over time, this gold layer can wear off or become tarnished due to exposure to moisture, chemicals, and even regular wear and tear. As a result, the once bright and rich color of the gold plating may start to fade and lose its luster.
Look for spots where the gold plating is visibly thin or has completely worn away. Understanding the current state of your jewelry will help you determine the appropriate restoration techniques needed to bring back its original shine and beauty. By thoroughly examining your gold-plated pieces, you can plan your restoration process more ...
Discharging the gold-contained wastewater is an economic loss. In this work, a set of ZnO/WO3 was facile synthesized by hydrothermal method in order to recover gold from the industrial cyanide ...

Gannon & Scott offers industry-leading expertise in recovering precious metals from plating solutions that keep your bottom line in mind. We use various methods to meet your needs, including precipitation, reverse …
5. It will take between 30 and 90 minutes to abstract the gold from the chip. 6. The gold will form flakes on the electrolysis plate, which you can scrape off and collect. So those were my instructions and that's all I'm trying to accomplish. I don't want a colloidal gold in water mix that I have to heat to recover after. I will save that for ...
