Pelletizing Process

iron ore His process involved grinding taconite to remove gangues and upgrading the iron ore (i e an ore beneficiation process) The resultant high-grade ore is in the form of fine particles as small as 0 1mm or less which are not suitable for sintering This issue led to the use of pelletizing Pelletizing plants are expected to play an Get Price

LKAB Mining Project

The iron ore is only considered ore when it is profitable and maintaining extraction in cost efficient ways is always on the agenda The process of dumping the iron ore into the mine shafts can be time consuming and wearing on machines As the LHD dumps the ore into the shaft some rock pieces (boulders) are to big to fit A picker is then used Get Price
