Abstract

Phosphogypsum has been reduced in the solid state by active charcoal both in the presence and absence of catalysts. Kinetic data could be fitted to the modified volume reaction model. Mixed catalysts like potassium dichromate were found to enhance the reaction rate quite satisfactorily. This result could be fruitfully employed during reduction with industrial coke also.
