But as soon as it is produced, $\ce{HNO3}$ will react with $\ce{HCl}$ in excess to produce "aqua regia", according to the equation : $$\ce{HNO3 + 3 HCl -> Cl2 + NOCl + 2 H2O}$$ And $\ce{Cl2}$ will attack pyrite | |

What is essential here is low activity of water and high activity of H+ and NO3^-. When based on HCl, there may be too much of water. | |
