| dc.description.abstract | n this paper, the separation of phosphorus from metallurgical-grade silicon was investigated based on an Mgalloying and HCl leaching approach. Experimental results show that P concentration was reduced from initial15.1ppmwto0.2ppmwwithalsolargeextentremovalofmetallicimpuritiesbytwotimesMgalloying-leachingpurification.ThemechanismofenhancedPseparationisclarifiedowingtothestrongaffinitybetweenMgandP,whichisvalidatedbySIMSelementalmapping.Atwo-parameteranalyticalmodelwasdevelopedtopredicttheP removal degree based on the variables of alloying metal concentration and interaction coefficient betweenalloyingmetalandP.Themodelisvalidatedwith experimentalresultsandtheinteractioncoefficientflg in “iXwasobtainedas−10.8.ThisapproachcanbeappliedtomodeltheremovalofimpuritywhichfollowsGulliver-Scheil solidification from other binary alloying systems.
