Abstract
A smelting process for making elemental silicon and alloys thereof is disclosed. The smelting process is of the electrometallurgical type for producing elemental silicon from silicon dioxide including silicon alloyed and silicon in a substantially pure form. The process includes establishing and maintaining countercurrent contact between collected oxide and a bed of carbonaceous reductant for reducing at least part of the collected oxide to additional elemental silicon.
