The typical multi-element chemical analysis in low-grade manganese ores is presented in Table 1. The grade of manganese in sample is 14.53%, which is much lower than the content of high-grade manganese ores. On the other hand, the contents of Mn/Fe and P/Mn are 9.02% and 0.0045%, respectively; and the alkaline coefficient of sample is 2.26.
