This paper deals with the purification of phosphogypsum by some processing such as washing with water, washing with lime milk, neutralization with lime and so on. It also covers the way to make plaster of Paris having good properties without washing. The result shows that the process of neutralization with lime is simple and the treated phosphogypsum can be used to produce the first grade of plaster.
