Characterization and Its Implication on Beneficiation of Low Grade Iron
Selection of processes for beneficiation through ore microscopic approach and parameters optimization was the prime interest of this research study. Noamundi iron ore, selected for this investigation, is one of the earliest iron ore mines in India. The iron ore deposits of Noamundi belong to Iron Ore Group of Precambrian age.

How to Process Copper Ore: Beneficiation Methods and Equipment
Copper ore beneficiation methods. Before the beneficiation of copper ores, crushing and grinding are required. The bulk ores are crushed to about 12cm by a jaw crusher or a cone crusher. Then the crushed materials are sent to the grinding equipment, and the final particle size of the copper ore is reduced to 0.15-0.2mm.
