Black sands are sandy deposits that contain a high percentage of heavy metals of economic importance because they enter into important strategic industries, and they are named so because they contain a high percentage of dark-black minerals (iron minerals) such as ilmenite and magnetite.
Black sand contains a percentage of economic minerals (ilmenite - zircon - magnetite - rutile - agate) and monazite, which contains radioactive minerals. Many countries extract heavy minerals from the black sands they host due to their economic importance. Also, the beaches are cleared of environmentally harmful radioactive substances

PRODUCTION: The total production is 25000 - 30000 ton per year and our plan is to increase the production to be 40000 during 2023.
â?¢ Our pebbles are used as a grinding ball into ball mills (ceramics industry) The high silica content ( 98.8%), and the hardness (7.5 on the Mos scale) as well as the rounding make our flint pebbles is an exceptional quality, with the local companies and the export territories.

Wall cladding is when a material is used to cover the exterior wall. It is important in areas such as kitchens and bathrooms to use a method like this to prevent the walls against water, heat or gas vapors produced when cooking. Without wall cladding in these cases paint will usually peel from the walls and walls can become damaged. To prevent this from happening wall cladding is the best solution and it can also be an attractive feature in your home. Marble finishing as rock face, split face and others similar to this gives the wall a unique look, more appealing than a plain wall. Wall cladding also has many other decorative purposes.

Limestone is a sedimentary rock composed largely of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO3).
we can reach up to 45 micron.
Uses limestone:
1- Portland cement industry: about 76 % that mix with nonmetallic minerals which is chemically treated.
2- Anhydrous sod carbonates: which is important to glass industry, detergence industry, purification industry, by reaction of co2 produce from calcinations with sod chloride and ammonia.
3- Catalyst in iron kilns: that iron have silica and ammonia as impurities which removed by limestone, they found that 410 kg of limestone produce 1 ton of iron.
4- Rocky fiber: by melting limestone in kilns and pumping steam strongly, so fiber formed which use as thermal isolation.
5- Lime industry: limestone is fired to lose co2 with 44 % from its weight leaving cao, that happen at 1000 – 1100 degree, which use in glass, paper building industry.
6- Metal filler: easy to grind, low oil absorption, do not cause machine corrosion isolation of tank and roofs,, painting and ceramic industries.
7- Food industry: the pure one for birds, treatment for sugar.
8- Ornamental stone: and building.
9- paper: In alkaline papermaking, calcium carbonate is used as a paper filler and coating. Both uses require high brightness, high purity, small particle size, and lack of abrasion.
10- coating: used white pigment in paints because it is available at relatively low cost and has high brightness for TiO2 extension, high purity, low abrasivity, and resistance to weathering.
11- plastic and rubber industry: used filler in plastics due to its low cost, low abrasion, low oil absorption, low moisture, high brightness, and easy dispersion with conventional mixing equipment, In plastics they are used to improve mar and impact resistance, surface gloss, weatherability, shrin
