उत्तर
Slag is a product of flux and gangue.
Explanation:
During the smelting process, metallurgists add a substance called a flux to the roasted ore to remove stubborn, infusible impurities known as gangue. At high temperatures, the flux chemically reacts with these impurities to form a molten, easily fusible waste product called slag. Because slag has a lower density than the molten metal, it floats on top and can be easily skimmed off and separated.
