In separation systems involving clays, SHMP was found to be a better dispersant than SS due to its higher adsorption that leads to high surface charge [3].
Weissenborn [13] also found that STPP is more selective as compared to SS and SHMP during the selective flocculation of ultrafine iron ore with starch.
Therefore in the dolomite-silica system and the apatite-dolomite system the use of SHMP and SS during wet grinding did not recovered the selectivity loss [3].
SHMP, SS, SPP, and EDTA are the abbreviations used for the dispersants sodium hexameta phosphate, sodium silicate, sodium pyrophosphate, and ethylene-diamine-tetraacetatic-acid respectively.
Similar to SPP, SHMP belongs to poly phosphate dispersant family therefore decreasing trend in sediment wt% with increasing SHMP indicate that dissolution of calcium poly phosphate complex is matured when the concentration of SHMP is reached to 0.
Above optimal SHMP dose increasing trend in sediment wt% suggest that coagulation or hetrocoagulation might be taking place due to increase in ionic conentration[13].
