The confirmation of the immiscible range of Sn-Fe system and the determination of the miscibility gap of Sn-Fe-Si system at 1, 350°C were carried out by means of distribution equilibrium method to obtain a fundamental aspect in the ferrosilicon process for treatment of hard head.
1) The immiscible range of Sn-Fe system was rather broader than the result of Mills and Turkdogan.
2) The distribution of tin between the crude tin and ferrosilicon phases was determined. When the silicon content in the ferrosilicon was 22-24%, the experimental results were most preferable, namely tin was below 0.9% in the ferrosilicon and it could be raised more than 98% in the crude tin.
3) The immiscible conditions were also discussed by using the image of electron probe X-ray microanalyser.
