production cost, low leaching rate, etc. Recently, our research group found that low-grade manganese dioxide ores can be reduced fully by CaS under mild conditions in aqueous solution. And manganese can... and waste gypsum boards [18,19]. Accordingly, making use of CaS to reduce manganese dioxide ores can not only reduce the cost, but also comply with the requirement of green economy. In this work......
