Stannous Chloride Test

[aga]

The gold solution was made as per Hoke, and it had not been de-nox'd before testing.

Edit to add:

The photos were taken immediately.

Left for 5 minutes there was no noticeable change.

Of course i didn't just throw them in the bin, and am not rummaging through the bin at the moment to collect all the gold-containing bits.

Honest

Ha! Save them up! Along with filter papers or anything else that gets gold solution on it. Even gloves, but I'm going to wait until I've got a better incineration set up before I burn those.

When you get enough saved to justify the time and acids they can be incinerated and leached to get that shiny shiny gold back.

Here is a good one by 4metals on the value of a drop of gold solution...

If you do refining regularly, all those tiny drops will mount up over the years, representing a large amount of $.

In my situation, losing that little bit of gold in order to get a handle on what the SC test can look like is worth the loss. My bin's GPS co-ordinates will be tracked, just in case.

I am happy to read this post .. here I also do a test with sncl2 mengahsilkan purple and didiamkam in more than 1 hour about how much ppm when viewed from its color

You can't tell the concentration of gold in solution just from a spot on a paper towel like that. You need to have a known solution that you know the concentration of to begin with and then do a dilution series as aga did in his post. The color depends on several factors where the quality of your stannous chloride is just one factor. But if everything else is the same then a dilution series can get quite close.

Your test doesn't look like it contains any precious metals much. If I got a test like that I would first test my stannous and if that is good then I would just dump it in my stock pot or maybe even going straight to waste.

Do some research on stock pot with copper scrap in it. Here is a link to get you started.

in this case i do on the rocks of gold veins ... sncl2 i made based on the hook method

the honorable mr aga here I send video link test results of gold veins using sncl2 ... I made based on the instructions in this forum on his advice and his opinion I am very grateful ... my question is whether the gold in the rock is high ppm

Hi
How much gold (in ppm) is in this solution approximately? What do you think?
It is cyanide solution and I tested it with stannous chloride.

You do not use acidic stannous chloride on alkaline cyanide. What I see is tin oxide

 

[saadat68]

Hi lino
As Hoke recommended, I add some HCl to cyanide test solution under my hood and then test with SnCl2
As you can see the purple color indicates gold but I want to know what is gold amount in test solution in ppm
