摘要：

HNO3 was calculated to have much more larger thermodynamical tendency to oxidate copper, nickel and iron sulphides than FeCl3. The frontline orbits theory also confirmed that NO3- reacted with nickel and iron sulphides more easily than Fe3+. The results of leaching Cu-Ni sulphide ore with FeCl3 and HNO3 were theoretically interpreted.
