It is shown that instead of the approach to magnetic control, which is justified for a number of bulk media, based on the polyoperative separation of masses of ferro-impurities by means of dry magnetophoresis, it is expedient to use a similar approach for ash waste, but based on wet magnetophoresis of ferro-impurities from an artificial suspension of the analyzed medium. In this case, the subsequent magnetic enrichment of the separated ferrous deposits is mandatory.
