Abstract

The present invention relates to a method of purifying a material using a metallic solvent. The present invention includes a method of purifying silicon utilizing a cascade process. In a cascade process, as the silicon moves through the purification process, it contacts increasingly pure solvent metal that is moving through the process in an opposite direction.
