Abstract

AI2O3및 Fe2O3품위가 부적합하여 유리 섬유용 원료로 사용키 어려운 중, 저품위 또는 고철분 함유 납석 및 납석질 도석을 유리 섬유용 원료로 공급하기 위해 건식 선택분쇄 및 분급방법을 적용하여 품위향상을 위한 "건식 선택분쇄 및 분급에 의한 납석 및 납석질 도석의 AI2O3품위향상 및 Fe2O3제거방법".Application of dry selective grinding and classification method to supply low-grade or high iron-containing feldspar and feldspar coatings as raw materials for glass fiber, which are difficult to use as raw materials for glass fiber due to inappropriate quality of AI 2 O 3 and Fe 2 O 3 "Development of AI 2 O 3 quality and removal of Fe 2 O 3 in feldspar and feldspar by dry selective grinding and classification".

Claims (1)

납석 및 납석질 도석의 AI2O3품위향상 및 Fe2O3제거를 위해서 종전의 유용 광물과 불순광물의 단체 분리를 위해 무차별로 미세하게 분쇄하는 방법을 지양하고, 구성광물간의 경도 차이를 이용하여 연질의 유용광물을 먼저 미립화 시키고, 경질의 불순광물을 굵은 상태로 남게하는 선택분쇄후 일정 입도를 기준으로 분급하여 납석 및 납석질 도석의 AI2O3품위향상 및 Fe2O3제거함을 특징으로 하는 "건식 선택분쇄 및 분급에 의한 납석 및 납석질 도석의 AI2O3품위향상 및 Fe2O3제거방법".In order to improve the quality of AI 2 O 3 and to remove Fe 2 O 3 in feldspar and feldspar pottery, avoid grinding finely and indiscriminately in order to separate single useful minerals and impurity minerals. The fine useful minerals are first atomized, and after selective crushing to leave the hard impurity minerals in a coarse state, they are classified based on a certain particle size to improve the quality of AI 2 O 3 and to remove Fe 2 O 3 from feldspar and calcite. "AI 2 O 3 quality improvement and Fe 2 O 3 removal method of feldspar and feldspar pottery by dry selective grinding and classification". ※참고사항:최초출원 내용에 의하여 공개하는 것임.※ Note: This is to be disclosed based on the first application.
