Abstract

By combining oxidative ladle refining with the introduction of a micro negative pressure (MNP) environment, the stable separation of P from metallurgical-grade silicon (MG-Si) was made possible. With the introduction of the MNP environment, the average relative removal efficiency of P increased from –1.9428 percent to 21.7638%. During MNP oxidative spoon refining (MNPOLR), P was not improved in that frame of mind rather was isolated by means of gas stage move. Regardless of the low limit of P and its exceptionally immersed fume pressure, the volatilization of P was constrained by gas dispersion during traditional oxidative spoon refining. The constant detachment of smoke by means of MNPOLR debilitated the dissemination opposition of P in the gas stage, effectively isolating P from MG-Si. As a result, MNPOLR is an efficient and widely applicable P-separation method.
