World resources are estimated to be greater than 800 billion tons of crude ore containing more than 230 billion tons of iron. The only source of primary iron is iron ore, but before all that iron ore can be turned into steel, it must go through the sintering process. Sinter is the primary feed material for making iron and steel in a blast furnace.

The plant will employ the KB 63-130 type gyratory crushers, which will be the largest crushers in the country. The crushers will be used to process raw iron ore from the pit and transfer it to the receiving conveyor. A slewing and luffing radial stacker will be installed to stack the secondary crushed magnetite iron ore onto a stockpile.
