what is slag how it is separated from metal...
Answers
Answer: Steel slag, a by-product of steel making, is produced during the separation of the molten steel from impurities in steel-making furnaces. The slag occurs as a molten liquid melt and is a complex solution of silicates and oxides that solidifies upon cooling.
Answer:
Slag is the glass-like by-product left over after a desired metal has been separated (i.e., smelted) from its raw ore. Slag is usually a mixture of metal oxides and silicon dioxide. However, slags can contain metal sulfides and elemental metals.
Slag being lighter floats on top of the molten iron "liquid". Every two to three hours, the molten iron and slag is drained from the furnace. After separating from the heavier iron, the slag is typically tapped or poured onto ground bays to air cool.
