    To produce standard ferromanganese (78% Mn) and a slag containing 30% MnO, the manganese-to-iron ratio in the charge must be 7.5:1. Since a single manganese ore of this ratio is seldom available, blending of ores from different sources is common practice to reach the desired manganese-to-iron ratio and to control the level of deleterious elements, particularly phosphorous.

    In the glass industry, manganese compounds are used for two effects. Manganese(III) reacts with iron(II) to induce a strong green color in glass by forming less-colored iron(III) and slightly pink manganese(II), compensating for the residual color of the iron(III). Larger quantities of manganese are used to produce pink colored glass.
