Abstract: The present invention discloses a method for refining mullite sand by using waste industrial waste. By recycling the discarded shell mold slag from the stainless steel precision casting plant, the shell mold slag is converted into After successive operations such as shell mold slag selection, crushing by crusher, shunt screening by magnetic separator, grinding and shunt selection by Raymond mill, and elemental testing, the finished product of fine mullite sand powder is finally obtained. The mullite obtained through this method is The mullite sand powder itself contains an appropriate amount of zirconium powder with an appropriate specific gravity, so its quality and effect are better than those of mullite sand directly produced from mullite ore. It can be seen that by using the method of the present invention, the industrial processes containing shell mold slag can be improved. Recycling and refining mullite sand from garbage not only saves materials, adds recycled renewable resources, generates very considerable economic value, but also treats sewage and protects the environment, which has extremely high social benefits.
