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 ,而尾渣是硅酸盐水泥的良好原料
The high temperature and high pressure hydration process was used to study the leaching of Al 2 O 3 and K 2 O from K-feldspar and the comprehensive utilization technology of tailings-burned cement. The results showed that the leaching rate of K 2 O was over 80% Leaching rate of up to 75%, while the tailings Portland cement is a good raw material
