Research and processing of shot blasting dust

Abstract

Dispersed iron‑containing waste makes up the lion’s share of solid technological waste of machine‑building enterprises. Most of this waste is still exported and buried in industrial landfills, while not only losing a signifi ant amount of metal, but also causing serious damage to the environment. At the same time, the modern state of technology and technologies, in particular, technologies developed by Belarusian scientists for recycling dispersed metal waste, make it possible to efficiently and cost‑effectively extract metals from most of the generated waste. This article presents the results of a study of the dust of shot‑blasting cleaning of castings formed in steel and iron foundries, and proposals for its processing and recycling of the metal contained in it.
