Hello Professor, I thank you very much for all the valuable information you provide. I am one of your followers. I ask you to provide a detailed explanation of reffining the metal iridium. think you sir.

[@colonialcharlie8702]

Great demonstration thanks.
The drill press stir is looking effective 😂
When you want to be sure the stir bar doesn't get bogged down, why not go big 👍

[@corveramoenglish7275]

Thanks for the alternative procedure overview for gold recovery. However this is Leagues away from the efficiency of vitrification with carbon and soda ash

اگر در ایران هستی برای آخرین بار پیشنهاد همکاری به شما میدهم .درحال ساخت کوره دوار هستم این پیشنهاد میتونه هرکسی را از فقر مثل من به ثروت برساند اما این ثروت را تنها نمیخواهم ثروت اصلی آرامش و شاد وطنم وثروتمندی همه هست چه بسا که توان ثروتمند کردن همه را ندارم ولاکن برای جوان مردها و حقیقت طلبان پیشنهاد دارم اگر جواب مثبت بود بعداز محک خوردن خواهی به نوایی رسید .این یک سخاوت حقیقی و از سر ایران خواهی ست .

Picky Plans I have a question. Can you recover the lead you use when you cupel the gold? Or is it just gone??
Thank you and I love your content please keep it up!!!!!!

[@PickyPlans]

Yes you can recover it by grinding the cupel and smelt it with some charcoal powder and borax.

[@edibandulan5266]

Why you want recovery lead from cupel? Lead is cheap and easy to find, in lead acid battery as example.

مرحبا عمل رائع صديقي هل يمكن استخدام حمض الهدروكلوريك ومبيض الغسييل الاذابه ذهب من صخور وهل هوه فعال ❤❤❤❤ شكرن لك

[@PickyPlans]

نعم هذا ممكن ولكن من الصعب استرداد الذهب من مثل هذا الحل. بالإضافة إلى أنك تحتاج أولاً إلى إزالة الحديد بحمض الكبريتيك أو حمض النيتريك

[@user-my4xn2wm5u]

اخي كيف يمكن ان استرجع الذهب من محلول المبيض والهدروكلوريك هل يمكن بزنك.

[@PickyPlans]

نعم وبعد استخدام الزنك فقط قم بمعالجته ببعض حمض النيتريك

Asalamualaikum Picky i have a question for you, i had a white fuming nitric acid and i belive the concentration is around 90% above but i watch a video about people who buy 60% nitric acid and that's already fuming, how to know exactly what my nitric acid concentration its?

[@PickyPlans]

First you can measure the density and look at the table for concentration . Second you can take a small sample and add a small piece of copper to it if it reacts vigorously you can make sure it's not +90% conc

[@edibandulan5266]

@@PickyPlans Hello picky i weight my nitric acid and 100ml nitric acid is weight about 121gram, that's mean my nitric acid concentration is just 40% but why that's white fuming?

[@PickyPlans]

That's just because of the reaction of NO2/NO with moisture in the Air.

[@edibandulan5266]

@@PickyPlans I can believe this i though my nitric acid is really concentrated almost anyhydrous but really the reason is because it reacting with the mixture in the air? Because its really fuming bro open that is a death sentence i have fuming HCL, H2SO4, and the nitric acid i always use that as a nitration procces, do you have another test to know the concentration, how about dilute it until 68% or 2.4 mol and then reacting it with the urea so 10ml 2.4mol nitric acid reacting with 7.2 gram of urea because that's the way to make urea nitrate and if the urea is percipitate that mean my nitric acid is "real" fuming stuff.

[@PickyPlans]

It's also a good idea. Also the cooper test could confirm it, since white fuming Nitric acid should react very slowly with copper until you add water
