Manganese.
In the context of manganese processing, manganese ores are roasted before electrolytic manganese production to obtain an MnO (manganous oxide) calcine. This calcine is then dissolved in sulfuric acid to create a manganous sulfate solution, which serves as the necessary precursor for the subsequent electrolytic process.1
