The concentrator processing method involves crushing the ROM in a primary, secondary, and tertiary cone crusher. The crushed ore undergoes grinding in 32 primary ball mills operating in closed circuits with spiral classifiers. The finely crushed ore particles are transferred to a flotation circuit for copper and molybdenum recovery.
