As shown in Fig. 3.6, the sand is usually fed to a “wet concentrator” or “primary concentrator” to produce heavy minerals concentrate (HMC), which is a mixture of ilmenite, rutile, magnetite, zircon (ZrSiO 4 ), and other high-density minerals. The wet HMC is fed to the LIMS to sort out the highly magnetic magnetite.
