The marine Eucla basin in southern Australia is emerging as a major new heavy minerals province in Australia. Beach placers are associated with a series of partially buried Cenozoic coastal barrier sands formed along an arcuate 2,000-km-long basin margin, the trace of which is up to 320 km inland of the present coastline.

Mineral sands are commonly mined by floating dredges, feeding floating concentrators at up to 2,000 t h −1. Such concentrators, consisting of a complex circuit of sluices, spirals, or Reichert cones, upgrade the heavy mineral content to around 90%, the feed grades varying from less than 2%, up to 20% heavy mineral in some cases.

Mineral Resources. Heavy Mineral Sands. Sedimentary deposits of sand, silt and clay often contain a small percentage of heavy mineral grains that have a higher specific gravity (greater than 2.9) than the more common quartz sand grains (about 2.65). Some are easily visible as dark and opaque grains, but others are light-colored or translucent ...
