grinding practice for iron ore fines



Influence of blasting on the size distribution and

ore passes the crusher and AG mills before entering the concentration plant Increasing the mill throughput of metal content is economically important The LKAB underground mines at Kiruna and Malmberget produce about the same amount of high grade iron ore that passes crushers and AG mills before being separated into fines and pellets material.
