| Popis: | 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. |
