| Abstract: | To callback ti-scrap acid by means of 2-step condensing.According to the FeSO4's solubility data in H2SO4 liquid,we put emphases on the mechanism and technics of normal pressure condensing,Aging crystal and vacuum condensing. After separating FeSO4 from ti-scrap acid,it can be used to produce ti-scrap with the density over 80%(weight).The dregs filtering and disturbing are also covered here. |
