摘要
研究了某一水硬铝石型高硫铝土矿的硫酸焙烧特性。试验结果表明:焙烧温度是影响铝、铁溶出率的主要因素;最佳焙烧工艺条件为焙烧温度350℃,硫酸与铝土矿的质量比2.75∶1,焙烧时间180min;最佳焙烧条件下铝溶出率超过83%,铁溶出率超过99%。
The sulfation roasting property of high‐sulfur bauxite was investigated .The orthogonal experimental results show that roasting temperature is a main influencing factor on leaching rate of Al and Fe .T he dissolution rate of aluminum is more than 83% and dissolution rate of iron is more than 99% under the best conditions of temperature of 350 ℃ ,the sulfuric‐to‐ore mass ratio of 2 .75∶1 , holding time of 180 min .
