Development of a Beneficiation Flow Sheet for Processing Silica Sand from Chertala Area of kerala

The silica sand from Chertala area of Alappuzha district has been reported to be of good quality. Presently, it is mined and transported to destinations inside and outside the State without any processing. A project on beneficiat-ion/ value addition of this sand was taken up as per the request from Directorate of Industries and Commerce, Govt. of Kerala.
Objective of the project is to develop a flow sheet for the total utilization of all fractions of this sand. The aim is to value add the same to produce special grade glass making sand according to BIS specifications (IS:488-1980), a suitable fraction for foundry application as per 1S:3018- 1977 and also to recover the finer fractions of sand and heavy minerals which are below 180,um and consti-tutes about 14% by weight. However, only the first two objectives are covered in the present work.
