Abstract: Chlorinated volatile-reduction roasting experiment was conducted in order to find the feasibility of one-step recovery gold and iron from cyanide tailing，using cyanide tailing(assaying 4.57 g/t gold，and 42.95% iron) from a gold smelting enterprises in Henan Province as research object，calcium chloride and sodium chloride as chlorination agents  (w(CaCl₂)∶w(NaCl) = 4∶1 mixture)，bituminous coal as reductant.Results show that on the dosage of chlorination agent is 10%，dosage of bituminous coal is 10%，calcination temperature is 1 000 ℃，the roasting time is 80 min，grinding fineness of calcined products is 75% -0.043 mm，magnetic field intensity is 106 kA/m，gold volatilize rate of 85.19%，iron concentrate with iron grade and recovery of 74.16% and 87.75% is obtained.Test results provide a new way for the recovery of gold and iron from cyanide tailing.
