India has vast resonrees in all the minerals required, for
the eeramic: industry, sufficient to meet the eountry' s requirements
for many years to eome. But they are not all of tlte
pu~·ity rcqnired l1y the various industrie.L If the products
of the Indian ceramic ind,nstries arc to maintain stan.iards
Mmparablc to those of foreign conntrie.~, steady sup ply of ·r,_I'IJJ
materials of the ?'cqni1·ed pnrity has to be ens ttred, and t lti.~ Mn
be done only by inst£t'li'l!f suit,zble plrozts for the elimin-ttion
of the undesimble impuritiel. TVaslting, .flot,ltiJn, magnetic
separation, etc .. are some of the important, p1·o~essel that could
be employed for the pn1'pose. As sueh plants are too costly for
the small operator.~, centralisctl lllants for beneficiating 1·aw
materials are suggested. Tlw bcnefieiation methods generally
employed for .•ands, quartz, felspar, clay.~, !cyanite, magnesite,
rutile, sillimanite, chromite, zircon, and graphite are prescribed
and· the specifications of the above requi1·ed, by the important
industries are also given. |
