The present invention relates to a method for manufacturing metal silicon and, more specifically, to a method for manufacturing metal silicon comprising: a step of supplying quartz ash and low carbon reducing agents to a furnace; a step of heating the furnace, applying arc-heat, making the quartz ash react with the low carbon reducing agents and obtaining molten silicon from the quarts ash; a step of supplying oxygen or nitrogen or a mixture of oxygen and nitrogen to the molten silicon and increasing purity by refining the molten silicon; and a step of solidifying the refined molten silicon and collecting solid phase metal silicon, and metal silicon manufactured thereby. [Reference numerals] (AA) Start; (BB) End; (S10) Supply quartz ash and low carbon supplying agents to a furnace; (S20) Carbon heat reduction; (S30) Refine molten silicon; (S40) Collect silicon |
