摘要:研究了消石灰和钾长石的加压反应条件,获得90%或更高的提取率。测得浸取反应级数为1.5级,活化能为45.5KJ/mol。比较了正长石型和微斜长石型两种典型钾长石的预处理条件,指明了浸取残渣的利用途径。
The Pressurized reaction conditions of slaked lime and potassium feldspar have been in vest igated andthe potassium extraction rate of 9 0%or more has been obtained. The order of reaction is mcasured to be1.5 and the activation energy is 4 5.5 KJ/mol.The pretreatment conditions of two typical potassiumfeluspaf normal feldspar and microcline are compared and the way of extraction residue utilization isindicated.
