Zusammenfassung: | The present invention relates to a method for removing impurities contained in low-purity waste solar silicon (purity of 90 to 95%) by an acid leaching method. The method includes: a preparation step of preparing waste solar silicon; a crushing step of crushing the waste solar silicon prepared in the preparation step; a first acid leaching step of leaching and separating impurities contained in the waste solar silicon by adding an acid leaching solution to the waste solar silicon crushed in the crushing step and stirring the same.
본 발명은 저순도의 폐태양광 실리콘(순도 90~95%)을 산침출 방법에 의해 저순도의 폐태양광 실리콘으로부터 함유되어 있는 불순물을 제거하는 방법에 관한 것이다. 그 구성은, 폐태양광 실리콘의 준비단계와; 상기 준비단계에서 준비된 폐태양광 실리콘을 파쇄하는 파쇄단계와; 상기 파쇄단계에서 파쇄된 폐태양광 실리콘에 산침출용액을 첨가하여 교반시킴으로서 폐태양광 실리콘에 함유된 불순물을 침출시켜 분리하는 1차 산침출단계; 를 포함하는 것을 특징으로 한다. |
