  • The separation of gold and vanadium in carbonaceous gold

    The separation principle of gold and vanadium in the carbonaceous gold ore can be described as follows: NaCl can react with vanadium to form soluble sodium vanadate and chlorine gas, and then the as-obtained chlorine gas can react with gold to form volatile gold chloride, thereby realizing the effective separation of gold and vanadium.
