Sinter mix gas-permeability declines with increase of its iron ore concentrate content, reducing throughput rate of sintering machines. The authors propose to solve this problem by means of using the Yakovlevskoye deposit sintering ore. It is only slightly inferior to iron ore concentrates with regard to iron content, but increases gas-permeability of sinter mixes by the factor of 2–4.

Sintering: A Step Between Mining Iron Ore and Steelmaking. The USGS defines iron ore as a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe3O4) and hematite (Fe2O3). It's a major ingredient in steel.
