sand in foundry depends on the casting, chemical composition, physical and mechanical properties in relation to its engineering application. This paper is centered on the characterization of some beach/river sand, with a view to determining the chemical composition, moisture content, grainCited by: 3
Sometimes they get concentrated in beaches or river bottoms to form beautiful and unusual looking sand samples. The composition of these sand samples is highly variable. The most common constituents of heavy mineral sands are garnet, magnetite, ilmenite, and epidote.

Plausible hypotheses often become established as generally accepted facts by the mere passage of time and the lack of a direct challenge. Geology has afforded, and stillCited by: 86
Heavy minerals such as tourmaline, zircon, etc can also be present in the sand in smaller concentrations. But from a high level, most sand on the beach is made up of gray or tan quartz and feldspar. However, the most common mineral in the sand is quartzalso known as silicon dioxide.
Heavy mineral sands are a class of ore deposit which is an important source of zirconium, titanium, thorium, tungsten, rare earth elements, the industrial minerals diamond, sapphire, garnet, and occasionally precious metals or gemstones. Heavy mineral sands are placer deposits formed most usually in beach environments by concentration due to the specific gravityof the mineral grains. It is equally likely that some concentrations of heavy mineral
