Optimization of the heat treatment of phosphate

Optimization of the heat treatment of phosphate[pdf-embedder url=”” title=”Article 1″]



  1. In this article, we studied the process of cold and hot mixing of sedimentary
    phosphates of Bouchane in order to optimize the energy requirements by reducing the organic
    matter and carbonates. The cold mixture is done at the ambient temperature whereas
    the hot mixture is made at the calcination temperature. The experimental process of the
    mixtures is performed under the atmospheric air using the same phosphate source and mixing
    in the same manner, in order to make possible the comparison between cold and hot.
    It appeared that the hot mixture using 33% of the same phosphate source can have an
    important impact on the energy saving while preserving the environment and responding
    to the quality requirements of the users.
