摘　　要：西南某铝土矿Al2O3和SiO2的品位分别为56.86%和14.86%,S含量为1.57%,为高效开发利用该铝土矿,对其进行同步脱硫脱硅试验研究。浮选研究结果表明:原矿在经过"一粗-一精-三扫"的闭路同步脱硫脱硅工艺处理后,可以得到Al2O3为61.03%,SiO2为11.95%,S含量为0.19,A/S为5.11的铝土矿精矿。该工艺可以为该矿的利用提供指导,同时也为该类型铝土矿的开发利用提供了一种全新的技术思路。The grade of Al2O3 and SiO2 of a bauxite in southwest China is 56.86%and 14.86%respectively,and the sulfur content is 1.57%.A simultaneous desulfurization and desiliconization experiment is carried out to develop and utilize this bauxite efficiently.The flotation research results show that the concentrate of 61.03%Al2O3 and 11.95%SiO2 can be achieved after"one roughing-one concentrating-three scavenging"closed-circuit test.The sulfur content of concentrate is 0.19%and the rate of aluminum and silicon is 5.11.This process can provide guidance for the utilization of the mine and a new technical idea for the development and utilization of this type of bauxite.
