Gold Dust to Gold Bar.wmv

[jabin48]

Once the gold has been cleaned or melted in the furnace, it is void of most foreign material. It is NOT .999 fine but it is a whole lot finer/cleaner than when it went into the furnace, no rock or quartz as this came out with the glass

cool video

I wish I had an electric furnace like that... Nice job though. If I ever get the right equipment and some gold, I will try this.

[Shavenhamster]

why dint he just but the ingot mold in the furnace with the gold in he wouldnt need borax as borax isnt good for graphite.

[doinen]

@Shavenhamster really? why? I do it all the time

[fleamine]

What is the reason for adding borox & boric acid to the mix?

What happens if you dont use borox & boric acid. Require more heat?

Interesting video, Teach me , a newbee.

Last post.The furnace seen here is obviously an electric one.What wattage is it and what is it's maximum temperature in deg C? How much would a unit like that cost?

[silver760]

Depending on the purity of this ingot,and it looks pretty good,may even be as good as 24K,at todays price 27.08.11 this little bar would be worth $2408.75,not bad for a little bottle of fines and vein material.I would be very interested to find out the purity of this ingot,as I said earlier the colour is VERY good,though if there was a lot of lode gold in there it may well have things like silver/palladium etc lightening the colour.Exciting stuff!! Well done!!Certainly worth your time doing

[silver760]

Did you say that some of this gold is "native" gold or gold extracted from a quartz vein mixed with other fines?I would have been tempted to have a go at getting some mercury and make amalgam with it,then drive off the mercury and retrieve the gold,the mercury vapour can be collected and condensed back to use again,but for such a small amount you could just let it go,just dont breath it in!!.Then refine the gold by melting with a little borax.

I enjoyed your video. Learned a lot and it encourages me to foray into refining. Thank you and good luck.

Borax is a thinner - correct and it also lowers the melting point of the gold. You can use borax powder - 20 Mule Team - or borax glass. I would recommend using a graphite crucible. The one in the video looked like it was clay. In the old days borax and a graphite crucible were the usual method. Thanks for the video.

[benglenda911]

how about if in your items still have silver, copper, gold , and others matter like granite? what will happen gold, silver and copper will be mix? hope to hear from you soon. thank you

,interesting

[boochieboy814]

Great video! I have a couple questions if you don't mind.

1. Borax is a liquefier right,,,,but what is the potash and niter for?

2. Where did you get that oven, and what was the cost?

3. Did you find all this fine gold yourself, or did you buy it?

Thanks very much, and that bar came out pretty nice!

[starshock01]

@boochieboy814 the oven he's using is a thermolyne, newer models are around $1000 usd, but older ones can be picked up at flea markets for around a couple hundred

[wilbeckj]

@starshock01 do they use gas to heat them? or electricity?

[starshock01]

@wilbeckj electricity, see the red light? that means its on, the meter next to the red light shows in the input

[jabin48]

I use 1 part niter, 2 part potash and 3 parts borax, for this mix it wauld have been about one tablespoon

[grendall69]

Can you please tell me the gramms of which you put borrax % borric acid you use per 45 grams off Gold dust .

Kind regards
