    The high-aluminous chromium ores containing about 15-18% of Al2O3 are widespread at Russian deposits, but their physicochemical and metallurgical characteristics are scantily known.
    We have investigated the effect of initial raw material form on viscosity and crystallization temperature of oxide melts. Besides crystallization temperatures and density of produced metal alloys were studied. It was established that in the result of Russian high-aluminous ores the slags having reduced crystallization temperature are obtained. The crystallization temperature of traditional slags formed at high-carbon ferrochrome smelting is higher by ~95°C. The produced ferroalloy with reduced chromium content (55-57%) and increased silicon content (3-5%) have reduced temperature of solidification onset (~1560 instead of 1620 iÑ), density (7290 instead of 7790 kg*m-3), the alloys are qualified by more favourable functional characteristics of steel treatment in comparison with widespread ferrochromium grade (with 62-65 % of Cr).
    Distinctive features of smelting technology of high-carbon ferrochrome made of poor high-aluminous raw materials were studied. It was discovered that in the result of high-aluminous ores application the residual content of total chromium content in the slag is increased up to ~7%. It was demonstrated the possibility of high-carbon ferrochrome grades production with the utilization of domestic high-aluminous chromium-ore raw materials. The finished alloy is suited to the requirements of FeCr60C70Si4LS grade of international standard ISO 5448-91.
