1 Ore properties and process 1.1 The nature of ore used in the mine test for a low-grade ore mine in Shandong, a whiteness of 68%. The mineral ore is illite, the main impurity minerals are iron minerals and a small amount of titanium minerals, the appearance of off-white. The results of multi-element analysis of crude chemical are shown in Table 1. Table 1 Analysis of ore chemical multi-element results Composition SiO2Al2O3Fe2O3K2ONa2OMgOTiO2CaO Loss on ignition /%
