Steel mill workers were also exposed to asbestos even if they were not participating in the actual manufacturing of steel, because building material such as refractory bricks on hot tops, floor and ceiling tiles, liner boards and asbestos blankets used for covering ladles, which were often discarded on the pouring pit floor, contained asbestos.
r RECOVERY OF MANGANESE FROM STEEL PLANT SLAG BY CARBAMATE LEACHING By Synthia N. Mcintosh 1 and Elizabeth G. Baglin2 ABSTRACT The Bureau of Mines investigated the feasibility of using ammonium carbamate (NH2C02NH4) leaching to recover manganese from steel plant slag.
Steel slag, a byproduct of converting iron to steel, is particularly well suited to civil engineering and infrastructure projects. Used as a substitute for natural aggregates, steel slag promotes a strong bond between the slag and asphalt, resulting in superior skid resistance and durability (see the sidebar, "Vroom Vroom").

Introduction. As a ubiquitous byproduct of steel production, around 61 million tonnes (Mt) of steel slag is generated yearly worldwide. Over half of this (33 Mt per annum) is produced within the USA and Europe (Proctor et al. 2000; Motz and Geiseler 2001), with an additional 27 Mt from China and Japan (Shen and Forssberg 2003), and Mt from Russia (Smirnov et al. 2009).
Managing construction and demolition debris. Construction projects both building new structures and demolishing old ones generate a lot of waste. Studies of Wisconsin landfills have found that materials such as wood, shingles and brick or concrete make up more than onequarter of the waste landfilled in Wisconsin each year.
