Manganese with a total impurity content of approximately 0.1 percent is obtained by the halogen process (for example, chlorination of manganese ore) and halide reduction. Less pure manganese is prepared using aluminothermy according to the reaction 3Mn 3 O 4 + 8A1 = 9Mn + 4A1 2 O 3 , as well as by electrothermy.
