Title:
SORTING METHOD OF RESIDUE SILICON MATERIAL MIXED WITH FOREIGN SUBSTANCE
Document Type and Number:
WIPO Patent Application WO/2010/069119
Kind Code:
A1
Abstract:
A sorting method of residue silicon material mixed with foreign substance is characterized in that: the residue silicon material mixed with foreign substance is put into a carbonate solution; the gas generated by the reaction of the carbonate solution and the silicon material drives the rest silicon material floating upwardly; the silicon material floated upwardly is taken out, and the separation of the foreign substance and silicon material is achieved; the sorting of residue silicon material mixed with foreign substances is accomplished. Said sorting method is a sorting method of residue fine crushing silicon material mixed with foreign substance. The sorted silicon material is mainly used in the reign of semiconductor and solar energy photovoltaic. The present invention employs carbonate solution to sort silicon material，and the sorting method is efficient. It is suitable for large scale sorting, and can substitute traditional manual sorting work completely.
