FIELD: metallurgy.
SUBSTANCE: method includes double-stage treatment of gases first in cyclones with return of trapped dust for melting process, then in metal fabric filters with dust production. After treatment of gases dust is removed from filters and further processed. At the same time dust after extraction from a metal fabric filter is loaded into a reservoir, binder is supplied, mixed to produce a paste-like mixture. Then the mixture is granulated to produce granules, which are dried and sent for further processing by chlorination. Using a suspension of sludge of carnallite chlorators makes it possible to additionally recycle wastes of magnesium production.
EFFECT: recycling of wastes in the form of granules in a titanium chlorator, reduced losses of valuable components, reduced pollution of environment.
