Disposing Of The Slag

When mineral coal was substituted for charcoal as fuel, the quantity of slag produced per ton of iron increased to some extent, but probably not in the ratio which the volume of charcoal slag bears to the volume of coke slag to-day, because in the early days of mineral fuel much leaner slags were used, it being impossible to carry as much lime

Coal Combustion Wastes groundtruthtrekking

Background. Burning coal produces a variety of solid wastes known as coal combustion waste or coal combustion products. These include coal ash (fly ash and bottom ash), boiler slag, and flue-gas desulphurization products. In 2007 over 120 million tons of these wastes were produced in the US, of which approximately 44% was reused in other applications.

Iron Recycling Cohen

These pieces enter the furnace along with coal (known as “coke” in this context), which provides the heat, and limestone, which makes any impurities in the ore rise to the top to form a layer called slag. Temperatures in the blast furnace top 3,000 degrees Fahrenheit. There are two basic types of iron: cast iron and wrought iron.
