A mixture of 3 parts HCl and 1 part HNO3. Can dissolve most metals, even the noble metal gold.
A small story: During WW2, Jewish scientists hid their gold Nobel Prizes in Aqua regia to prevent it being captured by the Nazis. When the war was over, it was mailed back to the Royal Institute who extracted the gold n recasted the prizes
