Processing

The MSP contains circuits which use magnetic, gravity and electrostatic methods to separate HMC into various grades of the finished products ilmenite, zircon and rutile.

The HMC is processed in the MSP where it is firstly dried. It is then treated through high-intensity magnets in order to separate the magnetic mineral ilmenite from the non-magnetic minerals rutile and zircon. The magnetic fraction is then further processed by electro-static separation to produce the final ilmenite product. A 50 tph ilmenite roaster and downstream magnetic separation plant have been built to further enhance the quality of the ilmenite products when required.

The non-magnetic fraction is treated in a wet gravity separation process to remove any remaining silica and low-density trash minerals. Electrostatic separators are then used to separate the conducting mineral rutile from the non-conducting mineral zircon.
