ABSTRACT
Major source of mining and metallurgical industrial wastes are considered. It is shown
that wastes contain valuable components, and may be used as raw materials for
metallurgy. But presence of non-ferrous metals and fine state of the majority of wastes
makes their processing by conventional metallurgical technology difficult.
Opportunities of smelting reduction technologies for processing wastes and extraction
of useful components are shown. Some facts and brief history of Romelt technology and
main stages of its development are presented. Operations of pilot Romelt furnace at
metallurgical works with the use iron-containing materials including wastes are
described. The potentialities of Romelt process for recycling of generated and current
iron-containing industrial wastes and improvement of ecological conditions of regions
are determined. Calculations of technological indices for iron-containing wastes using
Romelt technology are carried out.

Keywords: Romelt technology, iron-containing wastes, BOF dust, red mud
