Silica Grains / Sand for Foundry Industry

Natural moulding sand contains variable amount of clay, which acts as bond between the sand grains. This sand, therefore, posse strength, plasticity and refractoriness to varying extend depending upon the clay minerals present. When it contains a greater amount of clay, it is blended with river sand, which is relatively clay free so as to get the optimum properties desired in the sand mixture.

Silica Grains / Sand for Sodium & Potassium Silicate Industry

Sodium silicate is proposed by fusing silica sand or quartz powder (20 – 100 mesh) analyzing 99% SiO2and less than 0.25%; Al2O3, 0.03% Fe2O3, and combined CaO/MgO content of 0.05% with sodium carbonate at 1200° C to 1400° C. The ratio of Na2O3 can be varied to obtain a wide range of products.

Silica Grains / Sand for Ferro-Silicon Industry

Quartz suitable for ferro-silicon production should have more than 98% SiO2, less than 0.4% Al2O3 and not more than 0.2% each of Fe2O3, CaO and MgO. No phosphorous or arsenic should be present in quartz. If affects reduction in the electric furnace. Alkali has a tendency to promote a sticky slag that contaminates the products.

Silica Grains / Sand for Refractory Industry

Quartzite is use in the manufacture of acid silica bricks as it was high refractoriness. Refractoriness lowered by the presence of fluxes such as lime, iron oxide, magnesia and alkalies. The purity of raw material i.e., the high silica content is essential with least possible Al2O3. The presence of 0.01% Al2O3lowers the refractoriness of silica.

Silica Grains / Sand for Iron and steel industry

Quartzite is added to the blast furnace charge to correct silica alumina ration. The size of quartzite chips ranges from 10 to 80mm. The silica content should be 94% minimum and alumina 1% maximum. Some steel plants also use banded hematite quartzite in place of quartzite.

Silica Grains / Sand for Cement Industry

In cement industry silica sanded crushed sandstone are used as an additive to make for silica deficiencies in the raw mill. The silica content should be 65 – 98%, Fe2O3 –0.5- 6% Al2O3: 3.58 a0%, MgO: 1-105%. Standard sand as fine aggregate of particular specification is used for assessing the quality of cement in the laboratory by means of comprehensive strength test.

Silica Grains / Sand for Fertilizer Industry

Silica sand is used in fertilizer industry as filler to balance the fertilizer grades. There is no rigid specification for this industry. The size of silica sand should be 18 – 100mesh, with SiO2 content of 80% minimum and moisture 1% maximum. In some case even river sand is used.

Silica Grains / Sand for Silicon carbide and other abrasives

Silica sand and quartz are used in the manufacture of silicon carbide grains. The sand should for this purpose contain more than 99% SiO2, less than 0.1% each of Fe2O3 and Al2O3, no lime, magnesia and phosphorous. Similarly, quartz should contain 99.50 – 99.75% SiO2, 0.04 – 0.05% Al2O3, 0.05 – 0.10% Fe2O3, 1.10% CaO and MgO. Quartz is also used for the manufacture of sand paper / cloth.

Silica Grains / Sand for Chemical Industry

Quartz with +96% SiO2 is used in the manufacture of phosphorous-pent sulfide. Silica sand with +99% SiO2 and free of iron is used in the manufacture of ultramarine blue.

Silica Grains / Sand for Asbestos Products Industry

Silica powder with +97.5% SiO2, 0.8% Fe2O3 and 1.5% CaO is used as one of the constituents in the manufacture of asbestos – cement sheets and pipes.

Silica Grains / Sand for Insecticide Industry

Silica sand with +95% SiO2 is used as a carrier in the insecticide industry. The size of silica sand granules needs to be –15 +30 mesh. However, the specifications for this industry are not very rigid.

Silica Grains / Sand for Electrode Industry

Silica sand or quartz powder is used as one of the components of welding flux mixture in electrode industry, and for this purpose the silica minerals should contain 97.5 – 99.5% SiO2, 0.05% (max.) Fe2O3, 0.03% (max.) S, having + 100 – 200 mesh size.

Silica Grains / Sand for Coal Washery Industry

In coal washery silica sand is used as one of the ingredients in the flotation process of coal. Sand with a constant density of more than 2.64 is used. Grains must be sub-angular to round.

Silica Grains / Sand for Paint Industry

According to the BIS specifications (IS: 67 – 1979) the material should be of two types, namely, crystalline and amorphous. The material shall contain not less than 98% SiO2 and it shall be in dry powder form. Lead constant is SiO2 shall not exceed 0.03%. Color and particle shape shall match with the approved sample.

Silica Grains / Sand for Rubber Industry

Silica sand and quartz further are used as reinforcing filer to improve physical properties of rubber. Generally, silica mineral with + 98% SiO2 and less than 0.1% metallic impurities is preferred.

Silica Grains / Sand for Water Filtration

Sand and gravel are usually used as filter media for filtration of water.

Silica Grains / Sand for Sand / Lime Bricks Industry

Large quantities of silica sand are used making sand-lime building bricks. For this purpose sand may contain up to 2% of clay but it should not at any rate exceed 5%. It should be evenly grades. At least 10% should be sharp and angular, reasonably clean and free from organic matter.

Silica Grains / Sand for Plastering Mortars:

Natural and coarse sands are used in mortars for internal wall and ceiling plastering ans external plastering using mixes of lime, cement, gypsum and sand. The BIS specifications (IS: 1542 – 1977) for sand plaster are as under.
