| Abstract Scope |
Metallurgical methods of producing high purity silicon are highly desired because of their large throughput and low cost. However, the required impurity levels are impossible to achieve with only one step of extraction or refining. The present paper gives an overview of the concepts and research on the production of high purity silicon from silica by a combination of electrowinning from molten salt, slag refining, and solvent refining, which can take place in a sequence. The experimental works on the solubility of SiO2 in salt, electrodeposition of Si into a liquid Cu cathode, and slag refining of Cu-Si are presented. |
