A representative feed sample of Yellow sand was wetsieved in order to recover the desired fractions for glass making. The mass percentage of (–600 +300) μm and (–300 +125)μm fraction was found to be and % (ratio 1:).Hence, this ratio which satisfies the size specifications for glass making sand, was maintained for all the down stream processing studies.
Silica is an abundant mineral on the earth crust, and it is in sand, quartz and any other minerals. Some minerals have pure silica but in some, silica are mixed with other elements. In silica, the sulfur and oxyden atoms joined by covolent binds to form a huge crystal structure. Silica is also ...
Our selective high quality silica mines can provide high content of SiO2 raw silica with lowest impurities. Our Silica manufacturing plant can process the high purity raw silica sand by grinding and classifying the sand to meet all the silica industrial needs such as :
Sand is therefore the major constituent of glass, constituting from 52'to 65 per cent of the, mass of the original mixture, or from 60 to 75 per cent of the finished product after melting has driven o(F carbon dioxide, sulphur dioxide, and othec volatile materials.
Silica sand is a white or colourless crystalline compound, occurringabundantly as quartz, sand, flint, agate and in many minerals . It is used as an essential raw material in the production of glass, foundry, abrasives, filters, ceramics, in chemical and hydraulic fracturing and on oil fields [ 2 ].
