| 摘 要： | The feasibility and technologies of comprehensive recovery of tin, zinc, arsenic and iron from the complex iron ores by selective chlorination roasting were studied by thermodynamic analysis and roasting experiments. Investigation shows that the product pellets with the compression strength of 2 625 N/P, the tumble index of 97. 26%, the abrasion index of 1. 35%, tin, arsenic and zinc residue of 0. 043%, 0. 046% and 0.058% respectively can be achieved if bailing a concentrate containing 0.39 % tin, 0.40% arsenic and 0.28% with addition of 8% coke breeze and 0. 5% CaCl2 and roasting the pellets at 1 060 - 1 080℃ for 40 min. The volatilization of tin, arsenic and zinc is 91.75 %, 93.42 % and 81.12 % respectively. The performances of the product pellets are able to meet the requirements of blast furnace ironmaking.
