    Heavy minerals occur as sand grains mixed with lighter clays and quartz sand grains. Within the ore body, less than 5 percent of the grains may be heavy minerals. Two mining methods are used suction dredging and auxiliary mining. Suction Dredging An electrically powered suction dredge floats within a 15 to 20acre manmade pond. The dredge draws in overburden, ore and water from one end of the

    Heavy surface mineralisation occurs in the sand units near Namalope flats and Tupuito high dune areas. The HM sand deposits occur in a sequence of fine to medium grained and silty sands consociated with clay units. The mineralisation constitutes about 85% of ilmenite, 5% of zircon and 2% of rutile, with minute variations among the units.

    An important rutileilmenitezircon bearing sand deposit was discovered by local farmers at Eneabba, 300 km by road north of Perth in 1970. These heavy minerals occur in a series of ancient strandlines and associated dunal deposits at elevations from 85 m to 170 m above the present sea level and are situated,30 km inland. The

    Heavy Mineral Sand Mining with a Dredge

    The centrifugal force of the sand flowing down the spiral causes the lighter sand to be thrown out as tailings and the heavy minerals to be collected and upgraded to a wet product of approximately 75 percent heavy mineral. Approximately 50 percent of the 75 percent heavy mineral is titanium dioxide.

    Economic Heavy Minerals Offshore sand deposits often contain disseminated heavy minerals such as ilmenite (FeTiO3), leucoxene (altered ilmenite), rutile (TiO2), and zircon (ZrSiO4). These minerals are sources of titanium and zirconiumoxides used in the manufacture of pigment for paints, plastics, ceramic glazes, and other industrial uses.

    2. Sand is excavated from the pit. The heavier minerals are separated from the lighter minerals at the wet mill. Lighter sand is returned to the pit while the heavy mineral sand concentrate is trucked to the mineral separation plant for further processing. 3. Only about 2% of the sand is removed permanently.
