VALE is the world’s largest producer of iron ore, pellets, and nickel. To improve its production, VALE Oman has decided to build a 4th Ball Mill in parallel to the existing circuit to guarantee a production of 9.0 Mtpy, while avoiding any loss of production during the maintenance shutdown, and therefore increasing the annual production of pellets by 1.0 Mtpy.

The 4th Ball Mill project includes all units required for the implementation and operation of the new mill, modifications to the receiving ore silo and belt feeder, a new belt conveyor, a new slurry tank and the destination of the product into the mixers, all related utilities and infrastructures included. The new grinding system is designed to operate at a rate of 2.0 Mtpy (dry basis) while being able to operate at a rate of 1.0 Mtpy (dry basis).
