1. Iron ore crushing process: In the iron ore crushing process, the feeder, first crushing, secondary crushing, screening, fine crushing and dry selection are generally used. For the sake of economy, generally the finer the ore particle size entering the dry separator, the higher the proportion of ironbearing ore that is dry selected.

1. Iron ore supply and demand outline Types of iron ore Iron ores can be classified in different ways. The most important has to do with the iron content. In many cases, ore with a total iron content of 60% to 63%, or greater, is regarded as high grade, and ore with a lower iron content is regarded as low grade.

This is particularly true for some of the secondary grinding (primary ball mills) of magnetic iron ores. In magnetic iron ore grinding, the silica levels are continually being decreased from crushing to rod milling to ball milling by intermediate concentration steps. Subsequently, the wear environment becomes progressively less abrasive.
