There are several methods to recycle EAF fume dust for example. In particular one can collect the dust from the filters and then pellettize it: the pellets can be recycled into the furnace, in such a way you can increase the amount of zinc in the dust to about 30%. Zinc is a valuable material and several pyrometallurgical processes exist to extract zinc from EAF dust (for example the EZINEX process...).
