Processes for Beneficiation of Iron Ores IspatGuru

Iron ores normally fall within one of the three categories namely (i) direct shipping, or high grade ores, which contain enough iron to be charged to the iron making furnace directly and may only require crushing, screening, and blending, (ii) associated low grade merchant ores which occur around the high grade ores that can be mined

What Is The Crushing Process MEKA

Crushing is the process of size reduction of ore Size reduction process begins with usage of explosives at the area for production of ore In later stages, the size reduction process performed with crushers before grinding in mills is called "crushing" Although there is no limit set, the downsizing process over 3 mm is considered as "crushing
