washing at pit site yielded a sand grade assaying 88 per cent silica. The sand so produced was low in silica content and was contaminated to a considerable extent with muscovite, mica and other impurities. In the raw state, the sand sample was unsuitable for use in steel foundry and required beneficiation.
