    2019-4-15  The calcination and the reduction behaviors of a low-grade manganese ore by methane was studied at 973 K to 1273 K by several techniques. The onset temperatures of thermal decompositions of pyrolusite and calcite phases for this ore were found to be 868 K and 1056 K, and the rates of decompositions are obtained as 1.4 × 10−3 s−1 and 1.53 × 10−3 s−1, respectively.
