In South Africa, heavy mineral sands deposits

Geology of the Old Hickory Heavy Mineral Sand Deposit ...

The bulk of the older deposit is a clayey sand with 10-30 wt % heavy mineral. In pockets, heavy mineral grades can get quite high (up to 80%). These pockets are often located adjacent to the flanks of buried ridges of saprolitic bedrock. The sand is dominantly clayey quartz sand and locally white kaolinitic pseudomorphs after feldspar are common.

Mineral sands - Earth Resources

Heavy mineral sands deposits occur in the Murray and Gippsland Basins in northwest and southeast Victoria. The Murray Basin extends from Victoria into South Australia and New South Wales where mineral sands deposits have also been identified. Two types of mineral sands deposits are recognised in the Murray Basin.

Heavy Minerals Recovery from Sand & Gravel

Heavy minerals occurring in Oregon and Washington alluvial deposits include magnetite, ilmenite, hematite, chromite, zircon, garnet, radioactive minerals, gold, and platinum-group minerals. An extensive study of the heavy minerals (black sands) in the Northwest was reported by Day and Richards of the U.S. Geological Survey in 1905.
