Origin and prospectivity of heavy mineral enriched sand

Apr 01, 2018 The heavy mineral sand deposits observed along the Somaliland coast have the potential to provide commercially important heavy minerals, in particular ilmenite. It appears that prospects for development of the heavy mineral sands in the east of Berbera are better than those to the west of Berbera.

“Mineral Sands Deposits: their complexity and need for

The term “Mineral Sands” refers to sands which contain suites of minerals with high specific gravity (> 4 Specific Gravity) known as heavy minerals. Heavy minerals occurs as disseminated, associated or concentrated deposits within the sands. Found in an alluvial (old beach or river system) environment.

Feb 08, 2021 Mineral sands deposits typically comprise the following minerals of economic interest: Zircon is rich in the element zirconium. Rutile, leucoxene and ilmenite contain titanium. Trace amounts of monazite and xenotime contain rare earth elements. Other minerals such as magnetite and garnet may also be present in mineral sands.

mineral-sands

Mineral sand deposits are formed from the erosion and weathering of pre-existing igneous rocks such as granite, pegmatite and basalt. Over 60 to 200 million years the combinations of wind and water from ancient rivers and seas have leached the minerals from their past rocks and concentrated them into beach and dune deposits.

economic heavy mineral deposits may still remain undiscovered. Florida, the southernmost state of the USA, is known to the public for only one of its resources. This, of course, is the sand, which together with the sunshine makes Florida so attractive to tourists not only from America and, therefore, makes up the main revenue of the state.
