FIELD: process engineering.
SUBSTANCE: set of invention relates to production of composite materials from tungsten-containing mineral stock based on scheelite concentrate. Proposed method comprises charge preparation by mixing concentrate with aluminium-containing component and calcium-containing component and thermal recovery. Note here that, additionally, alloying components are added as a mix containing chromium oxide with cobalt oxide or with nickel oxide at weight ratio of chromium oxide to tungsten oxide in concentrate equal to (0.6-1.7):1, and that of cobalt oxide to tungsten oxide in concentrate equal to (0.5-1.4):1, or that of chromium oxide to tungsten oxide in concentrate equal to (1.0-1.3):1, and that of nickel oxide to tungsten oxide in concentrate equal to (0.5-2.2):1, respectively, and calcium fluoride is used as calcium-containing element.
EFFECT: ruling out power inputs in recovery, simplified procedure.
