中文摘要: 对不同添加剂(氧化镁、铁酸二钙、水化铁酸钙、赤泥磁选氧化铁的水化铁酸钙)替代石灰拜耳法对国内某铝土矿的溶出性能影响,结果表明,水化铁酸钙完全替代石灰效果最佳,当按C/S=1.3添加时,赤泥中N/S降至0.31,A/S降至1.2,溶出率提升至96.91%。通过本研究可优化生产工艺,开发新型添加剂,为氧化铝生产企业节能减排增产提供参考。
Abstract:The dissolution of a bauxite deposit in China is studied by different additives (magnesium oxide, dicalcium ferrite, hydro calcium ferrite, hydro calcium ferrite with red mud magnetic iron oxide) instead of lime Bayer process. The results show that hydro calcium ferrite is the best. When C/S = 1.3,the red mud N/S decrease to 0.31, A/S drop to 1.2, the dissolution rate increase to 96.91%. By the means of this study, can optimize the production process and develop new additives to provide a reference for the alumina production enterprises to increase energy-saving and emission-reducing.
