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.
The composition of mineral sand is highly variable, depending on the local . rock sources and conditions. The bri ght white sa nds found in tropical and subtropical .

The heavy minerals of the deposit comprise about 6% of the sand mined, and monazite makes up 0.5–7.0% of the heavy minerals (Shepherd, 1990). In addition to Australia, by-product monazite has been recovered from beach sands in Brazil, India, Malaysia, Thailand, and Vietnam.
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 gravity of the mineral grains.
The sand grains often have a palette of different colors and shapes. Most sand on beaches is composed of gray or tan quartz and feldspar. Quartz is a light-colored mineral, so your white sand beach will most likely have a lot of quartz in it. Darker sand comes from a number of minerals that are often denser and heavier than tan and quartz. A ...

In Malaysia, main source the of sand is from in-stream mining. In-stream sand mining is common practice becaa use the mining locations are usually near the "markets" or along the transportation route, hence reducing transportation costs. In-stream sand mining can damage private and public properties as well as aquatic habitats.
