Ontario railways before 1880: a scrap-iron bonanza
The construction of the first generation of railways in Ontario, Canada, was undertaken without the benefit of adequate capital investment. The result was cheaply-built track and rolling stock that wore out with unanticipated rapidity. Substantial replacement and design changes became a part of the railroad-building process. The failure – sometimes with catastrophic results – of poor quality iron ...

Model based optimization of scrap steel purchasing. Proceedings IFAC Mining, Metals and Metallurgy Symposium
Abstract: Scrap steel and iron ore are important feed stocks in the production of steel. Scrap steel is available on the open market as a commodity from various suppliers. The price and quality of scrap steel fluctuate and therefore require the periodic determination of the relative usage rate for each batch of steel made in a particular period of time. The determination of the usage rate results ...

A built-in zero valent iron anaerobic reactor to enhance treatment of azo dye wastewater
Waste scrap iron was packed into an upflow anaerobic sludge blanket (UASB) reactor to form a zero valent iron (ZVI) - UASB reactor system for treatment of azo dye wastewater. The ZVI acted as a reductant to decrease ORP in the reactor by more than 40 mv and functioned as an acid buffer to increase the pH in the reactor from 5.44 to 6.29, both of which improved the performance of the anaerobic ...

Like a phoenix from the ashes
Thanks to growing environmental awareness, waste is increasingly being separated and recycled. However, residual waste always remains that can't easily be recycled. This ends up in waste incineration plants (referred to as KVAs in Swiss German) for disposal and reclaiming, such as the KVA Linthgebiet in Niederurnen in the Swiss canton of Glarus. Due to the strict environmental specifications ...
