Abstract

The present invention relates to the recovery of silica from aluminosilicate-containing material and the production of solar and/or electronic grade silicon there from. In particular, a process for manufacturing silicon comprises subjecting highly pure and particulate silica in amorphous form to an in-flight plasma carbothermic reduction in a plasma reactor comprising a plasma torch and a vessel suitable for plasma-associated chemical reaction of silica and collection of liquid silicon. The highly pure and particulate silica is preferably produced using a process for manufacturing silica and/or alumina from an aluminosilicate-containing material comprising mixing the material with a metal chloride, preferably calcium chloride, being in the form of a solution or slurry, subjecting the wet mixture to a granulation step, burning the granules at a temperature of 900-1300°C, leaching the obtained heated mixture with hydrochloric acid to obtain a salt solution and insoluble silica, separating insoluble silica from the salt solution, and recovering dry silica. Alumina may be produced by crystallizing AlCl3 from the salt solution and heating the AlCl3*6H2O crystals to produce alumina.
