Disclosed is a method for producing silicon, comprising the following steps: a) fused-salt electrolysis of an SiO<SUB>2</SUB>-containing starting material along with antimony, mercury, and sulfur so as to obtain a soluble material; b) washing to remove the elementary sulfur; c) acid treatment to eliminate foreign ions; d) reduction treatment to reduce mercury salts and/or antimony salts; e) density separation to separate the silicon from the remaining components. |
