초록
본 연구에서는 정상 상태의 국내 금광산 선광플랜트의 분쇄/분급 공정을 전산모사 하였다. 분쇄 일지수와 에 너지 기반 경험적 모델을 활용하여 분쇄 산물의 80% 입도를 예측하였다. 실제 선광장의 볼밀 크기, 회전 속도, 볼 충전 율 등이 분쇄 모델에 적용되었다. 스파이럴 분급기는 Stoke 법칙, 습식싸이클론은 Plitt model을 이용하여 각 분급기의 분급입도 (d50c)를 산출하였다. 모델 및 변수들을 선광공정 시뮬레이터인 USIMPAC에 입력하여 공정의 전체 물질 수 지 및 입도분포를 예측하였다. 예측된 광액농도와 입도분포가 실제 결과와 높은 상관계수로 일치함을 확인하였다.
Abstract
This study on simulation was conducted for steady state grinding and classification processes in domestic gold ore mineral processing plant. In the grinding process, the 80% particle size of the ball mill products were predicted using work index and energy based empirical model. The actual operational parameters such as the size of ball mill, rotating speed and ball filling rate were applied to grinding model. The cut size (d50c) of spiral classifier and hydrocyclone were calculated using Stoke’s law and Plitt model, respectively. The models and variables were input to USIMPAC, a simulator for mineral processing, to predict the overall mass balance and particle size distribution of the process. It was confirmed that the predicted pulp density and the particle size distribution were in good agreement with the actual results from a high correlation coefficient.
