    For applications in which pure manganese is preferred, manganese ores are roasted to obtain an MnO calcine, and this isdissolved in sulfuric acid to form a manganous sulfate solution. The addition of ammonia precipitates iron and aluminum, and the addition of hydrogen sulfide precipitates arsenic, copper, zinc, lead, cobalt, and molybdenum
