用石棉矿渣制备轻质碳酸镁和白炭黑的实验研究

Preparation of light magnesium carbonate and white carbonfrom asbests slag

石棉矿渣经氯化焙烧、消化等步骤,再用碳化法和沉淀法分别制备轻质碳酸镁和白炭黑,产品纯度分别达94％和80％,具有良好的经济效益。

The asbestos slag are dealed with such processes as chloridizing roasting, digestion, light magnesium carbonate and white carbon can be prepared by carbonization and precipitation method separately. The productions' purity respectively amount to 94% and 80% .The technology has good economic result.
