Iron Ore Processing: From Extraction to Manufacturing
Cone crushers are capable of producing finer-sized ore particles compared to jaw crushers. The crushed ore obtained from the crushing stage is typically in larger size fractions and needs to be further processed through screening. 2. Screening. Screening is the process of separating the crushed ore into various size fractions.
