摘　　要：研究了白云石制备轻质碳酸镁的节能减排新型工艺,该工艺能有效地分离钙、镁物质,降低了主产中的钙含量,提高了轻质碳酸镁的质量和产量,讨论分析了常压碳化、加压碳化及重镁水常温分解三个反应阶段中的条件因素对产品质量的影响。This paper studied the energy - saving technology of the preparation of light magnesium carbonate. This process effectively separated calcium and magnesium from the product, reducing the calcium and increasing content of magnesium in the main product. Analysis the relationship between the conditioning factors in three reac- tion stage of normol carbonation, pressurized carbonation and re - magnesium water normothermia decomposition re- action and the quality of products.

关 键 词：轻质碳酸镁 加压碳化 重镁水
