construction etc. The natural silica sand is preferred in glass industries, but in cases when silica deposits are located far away, crushed quartz is used. Silica sand deposits are widely spread over a span of 110 Sq.Km area east of Gudur town in Nellore district of Andhra Pradesh (Fig.1). Present paper deals with estimation of silica

Quartz is a hard, crystalline mineral composed of silicon and oxygen atoms. The atoms are linked in a continuous framework of SiO 4 silicon–oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of SiO 2.Quartz is the second most abundant mineral in Earth's continental crust, behind feldspar.. Quartz exists in two forms, the normal α ...

For glass manufacturing pure quartz sand is required because iron affects the color of most glasses adversely. Thus iron should not exceed 0.45% for table ware, and 0.015% for optical glass. Partly for this reason establishing a glass factory is normally dependant on the location of the sand deposit in order to reduce the cost of operation.

metamorphic and sedimentary (Ketner,1973; Bourne, 1994). While quartz deposits are abundant, and quartz is present in some form in nearly all mining operations, high purity and commercially viable deposits occur less frequently. The composition of silica sand is highly variable, depending on the local rock sources and conditions.

The grade of a typical heavy mineral sand ore deposit is usually low. Within the 21st century, the lowest cut-off grades of heavy minerals, as a total heavy mineral (THM) concentrate from the bulk sand, in most ore deposits of this type is around 1% heavy minerals, although several are higher grade.

numerous in Asia and the Pacific region, but the largest of these are the gold-quartz vein deposits in Australia, China, and India and a number of hot-spring gold-silver deposits in the Philippines, Indonesia, and other countries (fig. 4, table 2). Small- to medium-size tin and tungsten lode and

in sand dunes helps geologists to distinguish dune deposits from other landforms. Because quartz grains can form from a number of different rocks, the original source of the quartz dune sand cannot be singled out. It should be noted that relatively few bedrock outcrops occur in Michigan. Instead, glacial drift almost completely covers the State.

Types of Sand Grains. The grains in a sandstone can be composed of mineral, rock, or organic materials. Which and in what percentage depends upon their source and how they have suffered during transport. Mineral grains in sandstones are usually quartz. Sometimes the quartz content of these sands can be very high - up to 90% or more.

Most high grade silica sand deposits occurs in form of sandstone formations that bounds the Arabian Shield to the north and east. Sandstone's deposits are in general friable, loosely to moderately cemented and require pulverization to yield silica sand. Majority of silica sand resources are white to off-white, it is moderately sorted sand with ...

Sand is a granular material composed of finely divided rock and mineral particles. It is defined by size, being finer than gravel and coarser than silt. Sand can also refer to a textural class of soil or soil type; i.e., a soil containing more than 85 percent sand-sized particles by mass.
