  • Phase changes in the syrian phosphorite–Ammonium Sulphate system
    Journal of Thermal Analysis and Calorimetry, 2006
    Co-Authors: V. Yaneva, I. Dombalov

    Abstract:

    With a complex of physico-chemical methods for analysis it is proved that in the course of mechanochemical treatment of a Syrian phosphorite and Ammonium Sulphate mixture new phases have been formed. The thermal analysis proves an increase in the reaction properties of the Ammonium Sulphate and the Syrian phosphorite which is a prerequisite for the increase in the content of P2O5assimilated , in the activated phosphorite mixtures and the possibility to use them in the production of NP complex fertilizers.

  • the effect of Ammonium Sulphate and ammonia on the liquid liquid extraction of zinc using lix 54
    Hydrometallurgy, 1999
    Co-Authors: Francisco Jose Alguacil, M Alonso

    Abstract:

    Abstract The extraction of zinc from Ammonium Sulphate solutions using LIX 54 as extractant has been studied. Experimental data show that zinc extraction decreases with increasing Ammonium Sulphate concentration of the aqueous phase. This decrease was attributed to the formation of metal ammine complexes in the aqueous phase which decreases the free zinc ion concentration. From the slopes of log DZn vs. pH plots, the extracted species has been found to be ZnR2; this stoichiometry was also confirmed by numerical treatment of experimental data and IR analysis of zinc loaded organic phases.
