菱镁矿制轻质碳酸镁消化过程最佳工艺条件探讨
The Study of The Optimum Conditions of The Digesting Process for The Manufacture of Light Magnesium Carbonate from Magnesia
【摘要】 通过测定苦土的粒度、液固比、消化温度和消化时间对灰分中 Mg(OH)2含量的影响,从而得到苦土消化的最佳操作条件为苦土粒度120目、液固比40:1、消化温度80~90℃、消化时间90~100min.
【Abstract】 By means of measuring the size of magnesia,the liquid-solid ratio,the digesting temperature and the digesting time,these influence on the amount of Mg(OH)2 in ash,we have obtaind the optimum conditions of the process of magnesia digesting;The size of magnesia is 120 wire mesh,the liquid solid ratio is 40:1,the digesting temperature is 353 ~363K and the digesting time is 90~100 min.
