The interaction of cyanide with pyrite, marcasite and pyrrhotite

•Adsorption energy of CN− on marcasite is the largest, then pyrrhotite, pyrite.•Charges transfer from pyrite, marcasite and pyrrhotite surfaces to CN−.•Fe of pyrite surface is bonded to C, while that of pyrrhotite bonded to N.•Carbon is bonded to sulphur, nitrogen is bonded to iron of marcasite surf...
