Description
Summary:The article presents an overview of the methods of processing slag from Waelz process, and various approaches employed by scientists globally, aimed at processing such slags. Despite several listed methods of processing slag from Waelz process, none entails a sufficient complex nature of its processing. In addition, the slag processed from the Waelz process, found in the dumps, has not been used as a secondary raw material to date. The elemental chemical composition of the slag has been determined, represented by compounds of calcium, silicon, iron, aluminum, carbon, and heavy non-ferrous metals, namely zinc and lead. Thus, it has been established that these slags continue to pollute the environment for many years.
