Love your inquaration videos, maybe even more than the silver cell ones. This one was a real pleasure: got a real sense of the workaday plate-spinning that must go on with multi-metals multi-refining. Keep up the good work, and have a great weekend.

As soon as teh video is posted, I started watching and half way through fell asleep. Now again I watch from the biginning. A beautiful gold bar. After watching your informative videos for quite some time, I subscribed to you.

I just never get tired of watching the gold drop out of that clean, clear chloroauric acid. It's just magic seeing that caramel colored broccoli form in the bottom of the beaker!

Note: Take all the precautionary safety steps while doing the experiment. 1) Reduce the % of the scrap gold to about 25% by melting it with sterling silver. 2) reduce the thickness of the molten metal by pouring it in the water, in a steel container. 3) put the metal in a beaker, boil it with nitric acid and pour the blue colored solution formed after boiling the metal solution, into another jar. ( From this blue solution, the silver is extracted by settling it with copper plates in another jar after extended period of time. ) 4) The metal in the beaker is rinsed with distilled water and poured into the silver-nitric acid solution jar. And it is added with diluted nitric acid, boil to extract the silver and other platinum group metals. This step is repeated until a clear solution is formed. 5) To the precipitate add hydrochloric acid and boil by adding sulphuric acid with a dropper, to eliminate any lead or other metals. The formed solution is then filtered out, cooled down by adding ice and precipitated by adding sodium-metabisulphate. The brown-waste solution formed in the beaker is collected into another jar, leaving the brown-gold metal in the beaker. This process is repeated until a clear solution is formed. 6) The brown-gold powder is then melted to get pure gold.

The gold bar is very beautiful and I like the shape of it. I wish I had the money to buy it.

My guess for a 5oz. Silver bar challenge is 11,700 ounces!! Lol Kidding on the 5oz, but the guess of 11,700 oz is an educated guess of 25oz. a week times 9 years! I took off a year because I'm guessing you weren't doing 25 a week at the beginning and I bought it down to 25 to average it out. I'm guessing you're doing well over 30oz a week for several years now!! If you read this Sreetips let me know what you think about my math and my knowledgeable guess on the silver.

An absolute thing of beauty bro. The work you Put into that is well worth the premium you are asking.

Never apologize for wanting to be paid for the work you do. People gotta know when you buy hand poured, its not just about the spot price.

Question regarding the process - rather than 92.5% silver, could you use an alloy of 50% silver, 40% copper, 5% zinc and 5% nickel? Reason I ask is that I’d prefer to use old coins as the catalyst as they are readily available here in Australia and can often be bought for less than silver spot price.

@sreetips how efficient is your process? If someone drops off 100g of 14k are you getting 58g of pure gold? Do you get anything else of value out of the refining process? Awesome videos I can’t stop watching!

Beautiful gold sreetips. You always do a wonderful job.

sreetips i believe your issue with your gold clumping on your cooling pot, is that your pot isnt deep enough. i would suggest, getting a much much taller pot, which is also as wide as you have and fill it most of the way up, to give the gold more time to cool on its way down... also, maybe pour higher up from the water, to allow the gold to break apart? just my thoughts on it, your the professional! keep making these great videos!

59:56 If I had to guess, it would be that you're adding a liquid solution, in part, with the gold. As to why you're getting the "spitting/bubbling" action. The solution is probably having to boil away before the metal can actually melt. You've taught all of us so much, however, with my guess, I'd suggest you dry your gold powder on a hot plate before melting. If you have any other idea as to why it's bubbling/spitting, I'd like to know. Thank you for your beautiful educational videos!!!!

@sreetips

The metal will absorb oxygen during the melt. Then it spits it back out causing the metal to appear to boil. Tiny balls of gold get ejected when this happens. I solved it by turning down the flame. No more spitting but it takes longer to melt. Silver is worse than gold for this tendency.

You can rid the gold solution of excess nitric by evaporation to a syrup, then rehydrating with HCl. Repeat until no more brown fumes evolve upon adding HCl. I’ve done it, it’s time consuming but it works. Or you can add sulfamic acid. But make sure lots of extra space because it will foam over

Around 35.51, you add sulfuric acid to precipitate lead that might be present. Then you add nitric till everything in the beaker is dissolved. Would the lead remain precipitated, or dissolve again with the added nitric? Could the final crumbs have been lead? Building my understanding of the different processes. Not doubting yours, only trying to understand fully.

@sreetips

3 жыл бұрын

Lead sulfate will not redissolve in nitric. Im merely adding the sulfuric just in case any lead might have made it that far into the process even though this is highly unlikely. I learned this from on old refiner. He taught me to add just a little sulfuric every time I dissolve the gold whether I suspect lead to be present or not. It hurts nothing and provides a huge benefit. Lead, in just trace amounts, will ruin the ductility and malleability of the gold. Adding a few drops of sulfuric acid guarantees that all of the lead will be 100% removed during the refining.
