The nonmagnetic concentrate will be upgraded using spiral concentrators and then be pumped to a hot acid leach plant (HAL) for surface cleaning of the mineral grains. They will then be treated in conventional magnetic, electrostatic and gravity circuits to produce zircon and HiTi88 leucoxene. Infrastructure at Sheffield Resources' project site
