文中以石灰拜耳法为前提研究了280℃以上的石灰拜耳法溶出与240℃溶出的比较。结果表明,280℃以上的石灰拜耳法溶出会显著地提高含水硅铝酸钙中的氧化硅的固溶量,从而进一步提高了石灰拜耳法应用的经济价值。
In this paper, the lime Bayer process for the premise of more than 280 ℃ lime Bayer method dissolution and 240 ℃ dissolution comparison. The results show that the dissolution of lime by Bayer process with lime above 280 ℃ can significantly increase the solid solution of silica in hydrous calcium aluminosilicate, which further improves the economic value of lime Bayer process.
