"Silica of commercial interest occurs throughout the whole of Canada as vein and intrusive masses and as sand, sandstone and quartzite deposits; and silica mining operations are conducted in all provinces except Prince Edward Island. Silica is recovered in lump form for use as metallurgical flux and in the manufacture of silicon and ferrosilicon alloys; as sand for glass and glass fibre manufacture, for use in foundry moulding, and for the production of silicate chemicals, silicon chips and optical fibres; and as finely ground silica flour for ceramic, asbestos cement and concrete products"--Abstract, p. i. gccst Minerals gccst Mining industry gccst Manufacturing industry Andrews, P.
