Recycling of dust-like zinc and iron containing wastes of electric furnace steelmaking

T.A. Lytaeva, A.E. Isakov

Abstract



Disperse waste caught in the cleaning systems of aspiration and process emissions are one of the least recyclable waste group of mining and processing enterprises. This dust is a technogenic raw material to obtain zinc and other metals. The hydrometallurgical method of valuable component extraction from the dust-like zinc and iron containing wastes of electric furnace steelmaking is developed by the authors and considered in the article. The basic technological and hardware-technological schemes of waste processing are suggested.

Keywords


dust-like zinc and iron containing wastes, ammonia-chloride leaching of wastes, ferrous cake, zinc concentrate.
