摘　　要：对贵州某高硫铝土矿进行了浮选脱硫试验研究。结果表明,在磨矿细度-0.074 mm粒级占82.64%,碳酸钠用量1800 g/t、硫酸铜用量150 g/t、丁黄药总用量600 g/t、2#油总用量240 g/t条件下,经一粗两精两扫闭路反浮选,获得了硫含量0.26%的铝土矿精矿,脱硫率达到85.86%。试验结果可为该类铝土矿资源的综合开发利用提供借鉴。A flotation test was conducted for the desulfurization of a high⁃sulfur bauxite ore from Guizhou Province.The results show that with the grinding fineness of-0.074 mm 82.64%,a close⁃circuit reverse flotation consisting of one roughing,two cleaning and two scavenging processes,with the dosage for sodium carbonate,copper sulfate,butyl xanthate and 2#oil of 1800 g/t,150 g/t,600 g/t and 240 g/t,respectively,can result in a bauxite concentrate with sulfur grade of 0.26%,showing the desulfurization rate up to 85.86%.The test results can provide reference for the comprehensive exploitation and utilization of this kind of bauxite resources.
