ABSTRACT OF THE DISCLOSURE A process for producing silicon in which a reaction mixture consisting, on the one hand, of briquettes produced by hot-briquetting of silicon dioxide (quartz) and carbon and, on the other hand, of granular quartz are introduced into an electric furnace and reacted so that silicon carbide is first produced and the silicon carbide then reacts with the quartz which fuses from the granular quartz, to produce elemental silicon.
