FIELD: construction industry.
SUBSTANCE: method of obtaining forsterite material from dunites is implemented by means of reduction fusion of dunite charge containing 10 wt % of carbon, by separating metal portion of fusion on the basis of iron, and the following granulation of silicate portion, either by discharging to water thus obtaining granulated material, or by compressed air thus obtaining hollow spheres. Metal portion of fusion is poured into moulds and used in metallurgy industry.
EFFECT: invention eliminates harmful effect of iron, nickel, chrome, impurities of aluminium, calcium and the necessity of charging with magnesite.
