摘要
利用高温高压水化学法对钾长石中Al2 O3,K2 O的浸取和尾渣烧水泥的综合利用新工艺进行了试验研究 ,结果表明 :K2 O的浸出率可达 80 %以上 ,Al2 O3的浸出率可达 75 %以上 。
Through high pressure hydrochenical process Al 2O 3, K 2O of potassium feldspar can be leached out and the leaching residues can be used as raw material of silicate cement. The experimental research results showed that the leaching rate of K 2O can reach over 80%, Al 2O 3 over 75%. The process is a promising technology in multipurpose utilization of potassium feldspar ore.
