Thegold refiningforum that I act as a moderator on [ed. note: goldrefiningforum.com] has done much work with the so-called "reverse electroplating" method ofgoldstripping using concentrated sulfuric acid as theelectrolyte. It can be used tostrip goldfrom most anything, including aluminum, without attacking the substrate metal (unless the solutiongetstoo hot).
Feb 13, 2012· The battery acid igetis in a normal beer bottle and is written 98% Sulfuric Acid on the bottle and it only cost me about USD50Cents for 450ml. Maybe all sulfuric acid for new battery is diluted, If so what should i do for 98% sulfuric? What is the recommend AMP for a 6v or 12v battery charger forreverse electroplating process.
Mar 28, 2017· Although it is possible to melt thegold platingaway from the circuitry, you will cause more of a mess and lose some of the precious metal. The most effective way to reclaimgoldfrom scrap components is to use aprocessreferred to asreverse electroplating.
Thegold platingon circuit boards will usually be 24 kt, or very close, but the issue is that theplatingis very very thin. On reasonably current computers it's probably something like 20 millionths of an inch on the tabs -- and half of that in other areas. Calculate how many square feet ofgold platingit takes togeta worthwhile amount of ...

Forreverse electroplatingit is necessary to use chemical solution. This chemical solution servers as a bath that helps ingolddissolvingprocess. Best known chemical bath forreverse electroplatingis a mixture of three different acids with ratio 70-15-15 percent of each.
Dec 27, 2017· Ok I saw some things in the tutorial area on the subject ofreverse electroplating. I built a cell, 12v at 1.aph with 50% sulfuric. Sometimes Igetbeautiful foils, sometimes no foils. The question is, is the brown looking sludge thegoldfrom the material that does not produce foils?
CONCERNS WITHGOLD ELECTROPLATING.Gold electroplatingis a very safeprocesswhen done by professionals. One concern withgold plating, however, is that it masks the other metals. If you have a metal allergy, you may be exposed to the allergen as thegold plating…
Goldrecovery from mining can also be done using a metal detector. Manygoldmining enthusiasts choose to use homemade sluices andgoldpans. This is a labor-intensiveprocess. Treasure maps and oldgoldmines often offer basicgold-mining tours and classes for a price, with guaranteed results.
High Quality (and Safe) Nickel Plating: Just like my popular copperplatinginstructable, the aim of this is to do high quality, low cost, and safeelectroplating. We will also be making our own electrolyte from scratch instead of buying chemicals online. If you've looked at my copper ...
The manufacturingprocessknown asplatingincludes many steps and requires considerable pretreatment, treatment and post-treatment steps. While there are several different kinds ofplatingtechniques, this how-to guide is intended to provide the basic procedural steps for the most popularplating process,electroplating.
Hello , I have areverse electroplatingmachine and have used salt water as the liquid to carry the currents. It works very well , a lot faster than chemicals I was using before( battery acid). It strips so fast but now I have a buch of this mudd it creates after. Dark brown mudd , yellow mudd, blue mudd. And I don't know what to do with it... do I just melt it down or something.
How to Take the Impurities outofGold. By Robert Paxton. ... The lead combines with other metals and forms oxide compounds that separate from thegold. Thisprocessworks best with small quantities ofgoldore. Submerge the unrefinedgoldin a mixture of nitric and hydrochloric acids. This method will dissolve the ore and separate thegold...
May 20, 2019·Electroplatingis very similar to electrolysis (using electricity to split up a chemical solution), which is thereverseof theprocessby which batteries produce electric currents. All these things are examples of electrochemistry : chemical reactions caused by or producing electricity that give scientifically or industrially useful end-products.
