Disposing Of The Slag - ChestofBooks
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 ...
