Fluorspar can be found in rock.

http://en.wikipedia.org/wiki/Fluorite

Sodium carbonate (soda Ash) can be found in powdered soaps (automatic dish washing soap here in US.

Borax also found in soap.
 
Franciz,

If you or your father have been melting gold and silver alloys for 15 years to collect all of those drums of slag, you will definitely have the skills to perform this process. I am not saying I cannot melt a sample for you, I'm saying I will use the same process outlined, most likely get back to you saying "Yep it works" and you will still be in the same position you are in now. Save your money from shipping me a sample and put your time into finding a source of fluorospar, just a few pounds at first to test the method yourself.

Another method you could try is to ball mill the borax and sift the powder. The borax will have to be completely dry before crushing. Sift the powder to 40 mesh and pick the pieces of metal off the screen. The bad part about crushing and sifting is the remaining powder will still likely have payable values which will have to be recovered by a large smelter.

I just Googled Fluorspar and found suppliers in China and India, surely one of your chemical suppliers can do the same.
 
You might inquire at your ''inspectorate'' for a source of fluorspar.

It is very important that you find this chemical, you need it far more than you realize.

When you do have the flux formula right all the valuable metals can be recovered the first time you run your jewelers wastes. Your new recoveries will be more profitable and you can recycle the past wastes.
 
Thanks for all,

I will try to get fluorspar and then try again and get back here with my result with few days.
I hope i will success once i get it.
Let me confirm again with expert here,

100g Slag(Used Borax)
100g Soda Ash
25g fluorspar
No lead needed.
Please let me know how long must i heat it? I am trying this small batch using charcoal furnaces.
Please correct me if i have missed out something or i am wrong....

Thanks and best regs..
Franciz....
 
For 100 grams of slag,

100 grams of new borax
100 grams of soda ash
25 grams fluorspar

Heat hot enough to melt the metal, at that point the flux will be very thin. You can verify how thin the flux is by dipping in a graphite stir rod to stir the melt and observing the thickness of the slag as it drips off the stir rod.

Pour it into a cone mold.

Get back to us to let us know how this works for you.
 
Sure, I will be back here with my result onces i have try this method but first i must try to get fluorspar first.
:lol: :lol: :lol:
I am going to city today to find fluorspar, I hope i can get it...
Thanks again 4metal...
Wish you all the best.

Dear all,

I have a serious question to ask, Today i have been to my local chemical store for ''calcium fluoride'' they say they can order for me but it is about USD83/- per 250grams.
I mean why it is so expensive?
Does anyone here experience buying in bulk, can you please tell me the price that you buy....
Thanks....
 
I purchased locally 1Kg for about 14$

When i asked them to quote me a pallet size order (above 500Kg), if memory serves me well, it was less then 3$ a kilo.

We are on very different places so this info might be somewhat irrelevant...
 
Find another source or try rock shops, you could buy the rock (almost pure crystal) on intranet and have shipped, or maybe find in chemical form online.

your almost reaching your goal, do not give up, we want to see that gold in your hand.

NAMES to look for____ calcium fluorite, CaF2, fluorite, fluorspar

Notice spellings fluorite (not fluoride), very important.

these my help?

Those that supply the ceramics or glass industries may be a good place to look locally.

It might be a long wait to get it from this company to Thailand.

Fluorspar in small and large quantities. This company also carries several other chemicals of interest to refiners.

This mineral is mined in Thailand it's hard to believe they don't keep any for use there.
 
Dear All,

Good news, I manage to talk to a local fluorspars supplier.

Dear all expert,

I have try to smelt it today,
100g used borax
100g new borax
100g soda ash, lght
25g fluorite 95%up

I smelt it for almost 2Hr, this method really really thin the borax and i was be able to pour it all to a cone mold i have made but i can see still alot and tiny metal color on top and middle of the cone mold(It refuse to sink all to the bottom) I have taken some picture using my cellphone with my finger pointing.

Please advice me what i have done wrong(i have already heated the cone to red hot and put some oil on it.)


The borax i chipped out from the cone mold is not clear, It is green color,red line, brown line and some are clear black like glass.

I hope i can success recover those precious metal in my used borax with the guide from expert here.....

Again i wish all people here all the best!!!!!!!!

Thanks for helping all the time
Franciz......
