This page mainly exists as a guide for mineral cleaning and preparation. For instance, let’s say you have nice Barite crystals, but they are embedded and covered over by Calcite. From the tables below you would find that Calcite dissolves readily in Hydrochloric Acid, but Barite is unaffected by it. So that acid could be used to etch away the Calcite, exposing the Barite crystals.

please sent solubility of Franklinite in aqua regia
I was not able to locate any information on Franklinite in aqua regia (or in nitric acid), but it is at least moderately dissolved in hydrochloric acid. Since aqua regia is a mixture of hydrochloric and nitric, I think is is safe to assume “moderately to readily dissolved”.
Is there any plan to include solubility in HNO3 (Nitric Acid) . Many minerals are insoluble in HCl and H2SO4 but are readily soluble in HNO3. When properly used, with PPE HNO3 is no more dangerous than HCl or H2SO4.
Yes. I have a source for that info – just need to transcribe it into HTML.
HNO3 data is posted!
