blast furnace slag disposal system
A slag disposal method for disposing of slags produced in furnaces during iron or steel making processes comprises employing the steps of magnetic sorting of masses of crude slags of a size greater than a value ranging between 300 to 500 mm obtained from the furnaces into slags rich in iron above about 50 to 60 percent and slags not rich in iron below about 50 to 60 percent

in the early days of the blast-furnace the slag was handled as clinker or ashes, and this method of procedure survived until very recent times in the crane-operated shovel, fork, etc., which i have described in a previous chapter as adjuncts to charcoal furnaces in the seventies and which were used to clean out and "work down" the furnace very
How is slag disposed of? - treehozz
Even though it can be recycled, slag is frequently sent to landfills for disposal. Slag is produced during the separation of the molten steel from impurities in the furnace, which is comprised of a complex solution of silicates and oxides that congeals upon cooling. Complete answer to this is here. In this manner, is slag hazardous waste?
