The present article contains the research results of electrosmelting the Achisay zinc oxide ore with extraction of silicon, calcium, iron, zinc and lead in a commodity output. It is found, that in a system of the Achisayore – carbon the calcium carbide formation begins at 1800°С, silicon and iron silicides – at 1500°С. Zinc completely passes in a gas phase at 1800°С, lead at 2300°С. At the electrosmelting the Achisayore (10,1% of Zn, 0,4% of Pb, 17,1% of Fe, 12,0% of Ca, 2,7% of Si) in the presence of coke and quartzite the ferroalloy with the Si content of 25,7-27,1% and the calcium carbide with capacity of 228 l/kg have been obtained. The calcium carbide capacity increases to 275 l/kg at the addition of lime in the charge (in this case the sublimates contain 44,34% of Zn). The suggested method of the zinc oxide ore processing allows to increase a level of complex processing the ore in 2,53 times.
