I found a piece of quartz with what looked to be either pyrite or chalcopyrite. One knowledgeable person told me it was pyrite and another told me it was chalcopyrite. I performed a wet chemical analysis to see if copper was present since chalcopyrite has copper and pyrite doesn't. I found the real answer in the lab.
I like how you did it for information purposes and to try the message yourself personally and then you found and ended up with results same or similar to where you learned the method from. Pretty cool and interesting I'm sure the chemicals that you use are expensive so most of the common folk can't do it. So appreciate you for your time and Valiant effort
I don't know where your original sample came from but most of my sampling is from Utah and Oregon and they often contain arsenic, as well. When I saw that yellow/orange color, I wondered if you would test for arsenic.. Love your basic set-up and thanks for discussing things as you went along. So few people do basic analysis and I';m glad you took the time. Thanks for ;sharing.and very well done!
Howdy Richard,
Sorry for not replying sooner as I somehow missed your comment. Thanks for the info. I did not test for As. The sample is from Virginia. I think I have the materials and can check for As. I will post the results as available. It might be awhile.
I agree and am surprised that it doesn't seem like much people are doing basic analysis which I am finding fun and gratifying. It is great to find answers in some cases or at least more information about a specimen.
Let me know if you want to discuss more off line. I can get you some contact info. if you do.

The presence of arsenic would suggest that you have Arsenopyrite
An excellent tutorial on analytical chemistry. Thank you so much.
Thanks so much for the comment. I try to be pragmatic and use that which is of some help to answer a question.
This is very interesting to me! I found some rocks with chalcopyrite and they were yellowish with blue underneath
Excelente vídeo.
Neat video, I enjoyed it. Would have liked to see a stannous chloride test as well.
Hello Tom, I found your channel today after collecting some rock samples from a local quarry this morning and wondering how I could roughly analyse their composition at home. I'm rediscovering an interest in chemistry at 50 plus and have always had an interest in geology. A wonderful way to combine the two and expand my knowledge of the physical world! Thank you for your informative video.
Cool. It sounds like we have similar interests. I am really enjoying some hands on stuff. Keep me up to date on what you find and get into.
@@ggsipaper I will do! On the hunt for a reasonably priced 'Identification and qualitative chemical analysis of minerals'. Step by step. Patience is the key.
Great experiment and nice video
Awesome video!
Thanks for the kind words.
cool video thanks it was interesting
Could. It become valuable if you had that all over yr land. Nice video.
Unfortunately, It wasn't on my land. I should look a little closer on my property but the grass always seems greener elsewhere. Actually there was a mine with pyrite / sulfides close to me. It was mined for the sulfur content to make sulfuric acid with the iron being a by product. Thanks for the comment.
Nice. I would be testing it for gold as well.

That's obviously Chalcopyrite even before you go on with your tests Chalcopyrite is mainly what people were mistaking as gold, not so much Pyrite.
After working with it a bit, it is apparent. Unfortunately, that was put in doubt after a long term and supposedly experienced collector and officer with a local gem and mineral club told me it was pyrite.
Yes, pyrite is more like brass while chalcopyrite is more like gold. The other iron sulphide pyrrhotite is magnetic and looks more like bronze.
Have you seen pyrite react with HCl? I have come across sources that say both yes and no.
Is pyrite an early stage formation of gold?
Can nitric acid also be used to determine if other metals are present in other mineral samples when heated up and displaying a certain color?
It is usually used in a specific procedure rather than by itself. The way a material acts in various situations may be a small clue in identification but not necessarily a definitive one.
@@ggsipaper thank you for the information.
The yellow liquid maybe gold.
I wish!!!
I have muriatic and sulfuric acid. Can I use one of those to dissolve my sample and from there do the ammonium hydroxide test?
What test procedure are you following? I am not familiar with the ammonium hydroxide test.
@@ggsipaper I'm attempting a color to form in the ammonia. Colorimetric type test.
@@ggsipaper I have samples of pyrite and Chalcopyrite that I would like to attempt to test with their certain indicating colors forming in the test tubes.
The iridescence is all you need to know its chalcopyrite.
How to meke gold from pirite or chacollpyrite into solution wiht iron sulfite made in russia me cambodia

Hey!
Avery complicated way to tell.
