| Abstract: | Trial production of magnetic pyrite weak oxygen roasting in Xingtai Hengyuan Chemical Group Co. , Ltd. is described. Factors influencing the weak oxygen roasting process in production were discussed to obtain the optimal process control parameters. Preparation of sulphuric acid by weak oxygen roasting magnetic pyrite prohibited the oxidation of iron effectively, turned Fe2O3 in the slag into F3O4, and obtained qualified iron concentrate, cut the cost and improved economic benefits by magnetic seperating the slag. |
