Locations of Deposits - Massachusetts Institute of …
Placer deposits form when minerals are separated by density as lighter minerals remain suspended and more dense minerals are deposited along the riverbed. Bedrock and beach sand deposits constitute the locations of the largest mines. REE-rich minerals are generally found in either carbonatites or peralkaline granites and associated pegmatites.
Heavy Minerals Recovery from Sand & Gravel
Because of the varying sand contents in the deposits, the amounts of minerals in the inplace deposits were not calculated. Results for samples from the Puget Sound area are shown in table 1. The samples contained 0.2 to 2.7 wt-pct HM. The major nonsilicate heavy minerals were magnetite, up to 9 lb/ton, and ilmenite, up to 3 lb/ton.

Australian mineral sands production in 2006 came from deposits, in order of importance, in Western Australia and Queensland. In the Victorian part of the Murray Basin, the Wemen mine, east of Mildura, was an important source of mineral sands from 2001 to about 2004, when it closed because of declining mineral sands grades.

MINERAL SANDS - Earth Science
Heavy Minerals Mineral sands contain suites of minerals with high specific gravity known as ‘heavy minerals’. Formation and Location Mineral sand deposits are formed from the erosion and weathering of pre-existing igneous rocks such as granite, pegmatite and basalt.
Sand Minerals - Sandatlas
Clay minerals themselves are not sand-forming minerals. They can not be because their size is not large enough to be considered sand. However, they are often present in sand as mud (when wet) or dust (when dry). Beach sands are generally free of dust and so are eolian deposits. Dust is present in many river and especially inland sand samples.
