The invention discloses a method for refining moraine sand by using waste industrial garbage. By recycling the waste shell mold slag from stainless steel precision foundry, the shell mold slag is selected, crushed by crusher, separated by magnetic separator, separated by raymond mill grinding and elemental analysis in turn, and finally the refined moraine sand powder is obtained. The moraine sand powder obtained by this method itself contains a proper proportion of zirconium powder, so its quality and effect are better than those prepared directly with moraine sand. Therefore, the method of the invention is used to recover and refine grinding sand from industrial waste containing shell mold slag, which not only saves materials, increases recycled renewable resources, and generates considerable economic value, but also controls sewage, protects the environment and has extremely high social benefits.
