hydrochloric acid and stannous chloride

[Lino1406]

If black does not persist - no PM's and HCl will only dissolve base metals

Blackness lasts for a long time if the solution does not evaporate, even for a week and a month :shock:
I know that HCl will only dissolve base metals, But this is a suspicious case that I have raised here so that maybe someone before me was involved in a similar case.

There are many minerals that contain chlorine.
I think HCL + CL Pm will dissolve if no preheating is done.

 

[Lino1406]

Sorry, no. Chlorine should be in the FREE state to act with HCl together.

I removed most of the annoying elements from the solution.

The color of the solution was yellow and the test was blood red.

Hi

I have never work with ore like this. If I were you I would prefer to see metals. Firstly I boil the material powder in AR than precipitate with zinc. By the means of that I can remove more active metals than zinc or Al. Then I check what I have. Then I would continue to work with sample. At least remain material cant change color with stannous chloride. It is just my two cents on the issue.

Usually with such samples, of which more than 20% is metal,
Zinc, aluminum, etc. are not the answer.
There are also simple ways to preserve precious elements
And that you get rid of annoying metals.

Have you tried cementation to see what cements out on copper or aluminium?

erol, I'm going to ask again that you translate your questions to English before you post them. You'll probably get more answers if you take the effort. Most members will not bother to translate your posts, and most of us don't speak Turkish. If you take the time to translate them one time, it's better than expecting hundreds of members to spend the same amount of time to translate them hundreds of times. Personally, at this point, I simply don't bother.

Dave is too soft (sorry Dave :wink: ). The next time I see you posting in Turkish without an English translation I'll ban you temporary. If that isn't enough then you could look forward to a permanent ban.
