Abstract
This chapter will give a short introduction to the well-described processes for the production of metallurgical silicon and solar grade silicon by the Siemens process. Among the new methods for the production of solar grade silicon, the upgraded metallurgical silicon is a good alternative to replace the feedstock produced by the Siemens process. Many of the new methods consist of several steps. The most common refining processes are described in this chapter. The intention of this chapter is to give an overview and understanding of the new processes that are emerging and to give some tools to optimize and develop new methods for production of solar grade silicon.
