【 摘 要 】

Manganese ores from Waykanan region (WK ore) contain pyrolusite (MnO2) as major minerals, whereas the main minerals in manganese ore from Tanggamus region (TG ore) are. The effects on manganese extraction of leaching reagents without reductant, leaching temperatur of non-reducing leaching, and reducing agents of sulfuric acid leaching were determined to investigate the leaching performances of the two manganese ores. Manganese leaching efficiency from WK ore is always higher than that from TG ore under the same leaching conditions. The mineral contents of the ores significantly affected the leaching performances and mineral dissolution behaviors of the samples.
