本文报道用加压水热法湿法冶金处理个旧霞石矿的研究结果。试验指出,采用含有Ca(OH)_2的氢氧化钠溶液两段加压水热浸取流程,可以综合回收钾、钠和氧化铝,而第二段浸取的硅酸钙渣则可用作制水泥的原料。
This paper reports the results of hydrothermal hydrometallurgy treatment of Gejiu nephelite. It was pointed out that a two-stage pressurized hydrothermal leaching process using sodium hydroxide solution containing Ca (OH) 2 could recover potassium, sodium and alumina synthetically while the second leached calcium silicate slag could be used as System of cement raw materials.
