Abstract

By the method of parching procedure and acid leaching to improve the phosphogypsum whiteness, and take advantage of the curve fitting technique of the Origin software to fitting the experimental data. Than, get the related curves and equation expression of the parching procedure and phosphogypsum whiteness during the heating process. Thereby providing a solution for the determination of the parching temperature. The results show that use curve fitting equation obtained calculate the required whiteness desired parching temperature. And calculate the range of the equation expression, that parching temperature control at 0 - 800 , whiteness range at 68.6% - 81.72%. Further increase parching time and change leaching conditions the phosphogypsum whiteness can be increased.
