本文研究了精矿铝硅比与选矿 -拜耳法工艺的原矿、碱、石灰消耗量和能耗的关系 ,计算结果表明提高精矿铝硅比将提高选矿 -拜耳法工艺经济效益 ,选矿尾矿铝硅比低于赤泥铝硅比时可提高铝土矿资源利用率 ,因此研究开发深度选矿脱硅技术具有重要价值
In this paper, the relationship between the ratio of aluminum to silicon in the concentrate and the ore, alkali and lime consumption and energy consumption in the beneficiation-Bayer process is studied. The calculation results show that increasing the ratio of aluminum to silicon in the concentrate will improve the economic benefits of the beneficiation-Bayer process, Aluminum-silicon ratio is lower than the ratio of red mud aluminum-silicon can improve the utilization rate of bauxite resources, so research and development of deep processing of desiliconization technology has important value
