Quartz is the second-most-abundant mineral in the Earth's continental crust, Throughout the world, varieties of quartz have been since antiquity the most commonly used minerals in the making of jewelry and hardstone carvings.
Sandpaper is used to add a nice, smooth finish to a piece of wood or to an object made out of timber. When a fine smooth finish is required on an object's surface, different grades of sandpaper are used to rub down the surface, starting with the coarsest grade and working through to the finest grade. The rough texture of the sand stuck to the surface of the paper scratches off the roughness of the object's surface making it progressively smoother. Frequently sandpaper is used between the application of layers or "coats" of paint. Sandpaper may also be used to file fingernails or remove rough areas of calluses on the skin.
A sand washing machine is widely used in the construction site, sand stone factory, the construction site of cement dam of a hydropower station, cement pre-cast parts factory, oil-well refilling and other industries.
Never heard of "insuluble." If you mean "insoluble", it means a substance that can't be dissolved within another substance. For example, sand is insoluble in water.
The Jaw Crusher is widely used in mining, building materials, chemical industry, metallurgy and so on. The Jaw Crusher is suitable for primary and secondary crushing all kinds of minerals and rocks with compressive strength less than 320 MPa. The Impact Crusher is used for primary, secondary, fine crushing mining and rocks (for example, the granite, marble, and limestone) materials with compressive strength less than 350 MPa. The impact crusher is widely used for sand and rock producing in the industry of roads, railways, reservoir, electricity power and building materials and so on.
India is producing 79 different minerals (excluding fuel and atomic resources). Main of them are iron ore, manganese, mica, bauxite, chromite, limestone, asbestos, fluorite, gypsum, ochre, phosphorite and silica sand.
Quartz
Sand is SiO2 and that is also quartz. So you will find sand on the beach.

Quartzite used to be quartz sand, generally well sorted and quite pure. Quartz has a great propensity to crystallize, so sand grains will tend to bind together.
Both sand and quartz have the elements silicon and oxygen. It is a crystalline structure. The crystalline structures of sand and quartz are slightly different.
Most sand grains are of quartz.
Yes, quartz sand is a compound, because quartz is a compound.

There are countless uses for quartz. The colorful transparent varieties are polished into gems. Opaque varieties are processed into ornamental items or building materials. Very pure quartz sand deposits are mined for the many items that use silicon, like computer chips.
Grinding quartz crystals down to produce sand is an example of physical change. When you grind quartz down to sand, you change the physical appearance of the quartz.
No Quartz sand is available on beaches and deserts all around the world.
