Gold Recovery with Reverse Electroplating - Part 2 Gold Recovery

- Decided to share with you my favorite method for gold recovery - Gold Reverse Electroplating. It is not the quickest method of gold recovery but is definitely one of the methods that covers all types of gold plated materials: from poor pins to thick gold plated objects.

Great Job! Im in the middle of setting up my lab now. I have been gathering for 2 years! Just making sure i have the science down and get all the correct equipment so i don't lose any gold! Great presentation
Hi, good luck with the lab! 🧪 I am chemist by education and it is real fun to me :) Hope same will be for you!
Excellent!!! I am excited about this method! Thank you so very much!!!
You are welcome!
Love from India ❤️
Hello from Kazakhstan 🇰🇿
Nice job 👍 GOLD🤠👍
Thank you!
To the iron sulfate are you supposed to add a little HCl ?
Hi, not really mandatory. There is a lot of HCl in the solution left from the aqua regia, in general. People add it to ‘make solution clean’ as in some cases iron sulphate has impurities.
Добро българско представяне!
Мерси!
I have tried to warm the sulphuric acid as you suggest but have had no luck. Hot hot do you get the liquid to. I am wary to heat it too much because of the horror stories I have heard about boiling sulphuric acid.
Boiling point of the conc. sulfuric acid is above 330 degrees Celsius, so it needs quite a lot of heating to boil. Always stay on the safe side. If not comfortable to boil it, just wait gold dust to go to the bottom.
@@escrapchannel totally! From the stories I have heard things get pretty crazy at 330 degrees without the correct tools and environment. Not a thing most people are prepared for. I didn't have a IR thermometer before but since I do now I took it to 120 and still not getting that result. What temperature did you have to get it to? Is it 250 as the text sort of suggests?
@gregdickson5107 Hi, heating sulphuric acid is dangerous. To coagulate gold I heat it to boiling point, unfortunately I did not measure the actual temperature.
@@escrapchannel Ok well I'm curious and I have the equipment to monitor it. I have no intention of taking it to 330C I will stay below 300C and see how that goes
@@gregdickson5107 Hi, I was surprised to see how gold dust coagulated into big peace’s. Hope you get some effect. In general I know some people add sulphuric acid when precipitating gold from aqua Regia to get coagulated in big peace’s result instead of gold dust.
Will there be problem if theres lead solder or iron/copper etc contaminating the gold plated objects. Can they all be present in Reverse electroplate cell without issue? Deciding if worth sorting materials or just run mixed
Hi, as the electrolyte is concentrated sulphuric acid it “favours” gold to be stripped while copper base or other metal stay mostly intact. Reaction depends a lot on the voltage, as higher current makes reaction faster but also impurities more. Gold product from the cell I refine chemically in all cases, so even if impurities present I clean gold during the refining.
@@escrapchannel great thanks I'll give it a try!
Please be super careful with the concentrated sulphuric acid.
every bit adds up
👍
Hello friend... Like a video, super job
Thank you!
How many grams did you recover?
Hi, almost nothin. Video was more to demonstrate the method.
@@escrapchannel cool cool. I've still learnt something and I have subscribed
Хорошее оборудование, и выход глаз радует 🎃
Thank you!
Привет,выход неплохой,лайк 👍
Thank you!
Дорова все быстро и понятно просто по картинке Лайкос
Thank you!
Nice one mate good job it looks good a little like making vodka lol.😂 except gold is probably better for you.👍
I will leave Vodka production to 🇷🇺, they are the experts! Will continue with gold 🤓 as much as I can!
@@escrapchannel Yeah mate I was having a laugh am just a crazy Scottish guy lol.😂😂
That’s what I definitely prefer - Glenlivet 🥃
@@escrapchannel About 40 miles from me mate lol.😂🍻
Ali Mack- Mechanical: Lucky you! 👍
That looks to be hardly worth the effort when all is said and done
Reverse electroplating is a slow method but if time is not a limiting factor it is cheap and reliable.
