초록
본 연구에서는 국내에 의치한 관인광산의 바나듐 함유 티탄철광(vanadium titanium magnetite, VTM) 광석 대상으로 기계적 분쇄에의한 결정구조를 평가하고자 다양한 조건에서의 유성 볼밀을 통한 기계적 분쇄를 수행하였으며, 산물에 대하여 결정구조 거동을 평가하였다. 사용된 관인광산 VTM 광석은 자철석과 티탄철석이 주요 광종이며, 주요 맥석광종은 철기반 실리케이트로 확인되었다. 유성 볼밀에 의한 기계적 활성화 결과에 따르면 분쇄메디아(볼) 크기는 크기가 작을수록 결정화도 및 결정크기가 감소하였으며, 시료/볼 충전은 시료가 투입이 적을수록 무정형화가 크게 일어남을 확인되었다. 게다가, 분쇄운전 변수인 분쇄속도 및 시간은 증가할수록 결정구조의 변화가 크게 관찰되었으며, 볼 크기 및 시료/볼 충전비보다도 분쇄속도 및 시간에 의한 결정구조 거동의 영향을 크게 주는 것으로 확인되었다.
Abstract
In this study, mechanical grinding using a planetary ball mill was performed under various conditions to evaluate its effect on the crystal structure of vanadium titanium magnetite (VTM) ore from the Kwain Mine in South Korea. The crystal structure of the activated product was also evaluated. Magnetite and ilmenite were identified as the main types of VTM ore used in the Kwain Mine, and the main types of gangue minerals were iron-based silicate minerals. According to the mechanical activation results, the crystallinity and crystal size decreased as the size of the grinding media (balls) decreased, and the amorphization of the sample/ball filling was significant as the amount of the sample was reduced. In addition, as the grinding speed and time increased, the crystal structure significantly changed, proving that these two parameters had a greater effect on the crystal structure than the ball size and sample/ball filling ratio.
