| Abstract: | The effects of molar ratio of C and O, reduction temperature and reduction time on the direct reduction of Panzhihua's pyrite residue were studied by conducting orthogonal experiments and single factor experiments. The results show that the main factors affecting the direct reduction of pyrite residue are in the following descending order: molar ratio of C and O > reduction temperature > reduction time. It is concluded that under the following optimal technique parameters including the molar ratio of C and O of 1.3, reduction at the temperature of 1 300 ℃ for 35 min, the metallization rate of the reduced pyrite residue can be up to 97.16%. |
