Sibelco high quality Olivine may be used as a cost effective slag conditioner for the production of pig iron, either as a component in the sinter feed or as an aggregate to condition the blast furnace. Olivine may also be applied as a mix with iron ore to produce fluxing pellets for direct charge to the blast furnace. Olivine offers enhanced MgO contribution as compared to other basic slag conditioning minerals, including dolomite, magnesite and serpentine.

The Olivine in our products will give high refractoriness combined with interesting thermal properties. Sibelco’s steel mineral portfolio is divided into three main categories:

Metallurgical Grade Olivine

Olivine can be used as a source of Magnesium Oxide (MgO) for cost effective slag conditioning of the blast furnace in pig iron production. The Olivine, MgO, may enter the blast furnace through several alternative routes:

  • As a component of the Sinter feed
  • As a component of Fluxed Iron Ore Pellets
  • As an aggregate for Direct Charge

Tundish Wear Lining

  • Wet spray masses
  • Dry product – cold setting
  • Dry product – thermal setting

Engineered EBT aggregates
