Study on the Calcining Conditions for Phosphogypsum Calcinin

Deng Zhi-tuo

Abstract

A effective way of phosphogypsum comprehensive utilization is to calcine the phosphogypsum(CaSO 4 ·2H 2 O)to stucco(CaSO 4 ·1/2H 2 O)which is widely used in the field of building material.The paper is for the study of calcining condition,additive,and grinding time and determines the basic conditions for phosphogypsum calcinin.
