<P>PROBLEM TO BE SOLVED: To provide a method of recovering silicon that regenerates silicon to recover from a recovered silicone waste, particularly from a recovered silicon waste containing silicon oxide and silicon carbide, and a method of recovering silicon that regenerates ferrosilicon which can be used as it is. <P>SOLUTION: The method of recovering silicon comprises remelting a recovered silicon waste containing silicon oxide, or silicon oxide and silicon carbide by arc discharge with molten slag to regenerate silicon wherein the remelting is carried out at a temperature of the molten slag of not lower than 1,750°C. <P>COPYRIGHT: (C)2012,JPO&INPIT |
