.
Standard Grade Rutile (SGR)
Industrial Grade Rutile (IGR)
High-grade ilmenite
Zircon-in-concentrate (ZIC)
Dry mining: truck and excavator with dozer support.
Four wet concentrator plants (WCPs) producing mineral
concentrate with feed capacity of 500-600tph.
Mineral concentrate from Area 1 is processed in the mineral
separation plant (MSP), which includes a feed preparation plant
and dry plant. The MSP has capacity to produce 175ktpa of
