Abstract

The Railways' holdings of non-ferrous metals are estimated to exceed RS. 21 crores and a substantial portion of this amount is accounted for by the copper and copper base alloys. The annual outturn of the railway non-ferrous foundries amounts to about 23 thousand tonnes and accumalation of non-ferrous scrap at the end of March 1967 were reported as 11,400 tonnes. The value was esti-mated as Rs. 2.62 crores. The Railways reclaim most of their non-ferrous scrap arisings in their foundries; during the year 1966-67, 19,604 tonnes of non-ferrous scrap, mostly copper base, was utilised by the Railways for their own use and 1469 tonnes was disposed of to the trade.
