As the opencast mining of Ekou Iron Mine comes into late stage,mineral processing costs are on the increase year by year as dilution rates of mined ores increase,but grades of feed ores decrease.Through the study of ore fines dry-type magnetic separation process,a series of key technologies have been developed by the means of embedding the new process of ore fines dry-type magnetic separation in the old process of grinding and classification,thus enabling the application of ore fines dry-type magnetic separation process in old mines to achieve success.
