中文摘要: 采用微波焙烧脱硫工艺研究了微波加热温度、微波加热时间和矿物粒度对高硫铝土矿中硫含量的影响及氧化铝溶出率的影响；并且依据原矿和微波处理后铝土矿的XRD谱，探讨了高硫铝土矿的脱硫机理。结果表明：微波加热温度为650℃、微波加热时间为5min、矿物粒度为0.095~0.076 mm时，高硫铝土矿的硫含量可以从4.15%降低到0.37%；在试验条件下，可以使氧化铝的溶出率从80.4%提高到98.7%。
Abstract:The effect of heating temperature, heating time and mineral size on sulfur content adopting the process of microwave desulfurization and the digestion performance of bauxite are studied; and according to XRD spectra of raw ore and ore dealt with microwave, the desulfurization mechanism of high sulfur bauxite are also discussed. The results show that sulfur content of high sulfur bauxite decreased to 0.37% from 4.15% in microwave heating temperature 650℃, microwave heating time 5 min, mineral size 0.095~0.076 mm; under experimental conditions, digestion of alumina may be promoted to 98.7% from 80.4%.
