| 摘 要： | 在低温拜耳法生产氧化铝工艺中,三水铝石型铝土矿的质量优劣直接影响其生产的经济技术指标,而评价矿石质量优劣的最主要指标是活性铝与活性硅的比值,即有效铝硅比.本试验旨在通过选矿的方法,依据三水铝土矿的矿石特性,采用分级浮选流程,提高低铝硅比三水铝土矿的有效铝硅比.试验获得了较好的技术指标,总精矿的铝硅比为5.41,有效铝硅比为11.07,三水铝石的回收率为92.41%.

| Abstract: | In the alumina producing process by Bayer at low temperature, the quality of gibbsite bauxite ore will directly affect production economical-technical indexes, and the main indexes of evaluating the ore quality are the ratio of active aluminum and active silicon, that is effective Al-Si ratio. According to the ore characteristics of gibbsite bauxite ore, adopting classification and flotation method to improve the effective Al-Si ratio of gibbsite bauxite ore with low Al-Si ratio. The test has obtained bette... |
