Through the analysis of the test and industrial production data of Jingtieshan Iron Mine,it is concluded that the content of alkali metal and zinc will not change during the magnetization roasting process,and the change of sulfur content depends on the occurrence form of sulfur.In the process of calcine milling,the change of alkali metal and sulfur is nega-tively correlated with the grade of iron.The higher the grade of iron,the lower the alkali metal and sulfur,and neither en-richment nor reduction of zinc in the process of sorting.
