GeneralSolubility of some Cu minerals
6th Jun 2012 05:11 UTCAnonymous User
I would like to be able to indentify some Cu minerals with the solubility test, but I can't find the information about that.
I try find a reliable sourse of information about the solubility in H2O and HCl for the following minerals:
Malachite, Brochantite, Antlerite, Atacamite, Chrysocolla, Azurite, Chalcanthite
I would apreciate all the answers you could provide me with.
Thank you.

Malachite: any mineral acid (including HCl)
Brochantite: any mineral acid
Antlerite: HCl, H2SO4
Atacamite: any mineral acid
Chrysocolla: insoluble
Azurite: any mineral acid, slightly soluble in H2O
Chalcanthite: H2O

Given that I need the tests for field work (not lab): How can I tell the difference between Atacamite, Brochantite and Anthlerite?
Is there any difference in the cinetics of the dissolution in HCl that I could notice? Any other test for field work?

I don't know if this is of any help.
By the way, thanks for all the answers.
You have been all of a lot of help.

Is there a data base accessible for these minerals? Does somebody have it?
Thanks!

I need special help, I need Kps (solubility constan) to brochantite (Cu4SO4 (OH)4), any can help me.
best regards,
