Sommaire: The closure of the iron and steel making plant at Consett in Durham in 1980 marked the end of an era—a long era in the world's iron and steel making history. Iron had been smelted in the Tyne- Wear area of the United Kingdom since before the Roman period, but apart from evidence of smithing in the Roman period, the historical evidence for iron production on a large scale dates from the 14th century.
The paper describes sites in the area that first worked the bloomery process and then,...

Sommaire: The use of Caro 's acid as a replacement for hydrogen peroxide for the oxidation of vanadium prior to solvent extraction resulted in a 56% reduction in oxidant usage when compared on an equivalent hydrogen peroxide basis. Comparative oxidation tests, using two actual uranium mill raffinates, resulted in premature precipitation of an amorphous ferric vanadate when hydrogen peroxide was used to oxidize one of the raffinates containing a high iron to vanadium ratio. The use of Caro's acid...
