The system can determine the iron ore grade within 5 minutes. Compared with similar systems, this online analytical system has the ability to deal with the problems of poor sampling, poor on-site conditions for online iron ore analysis, variation in the moisture content of samples, the matrix effect and spectral drift. The system has been applied to iron ore grade evaluation in the Panzhihua Iron and Steel Company, China. Practical tests illustrated that the system can effectively improve iron ore grade evaluation.
