Question

How would Quartz react with hydrochloric acid? I know precious metals are refined through acids and dissolution, but what about using hydrochloric or nitric acid on quartz, would it react with the silicon dioxide and dissolve the quartz leaving behind the metals that arent affected by the acids?

Answer 1

SiO₂ does not react with any of acids except, HF. This means that the reaction (SiO₂+HCl) is not occuring.
