The use of olivine sand absolutely eliminates the risk of professional disease of molders which is called silicosis!

The use of olivine sand will improve the metallurgical properties of pellets of your production:

  • Due to the high content Of MgO, olivine sand increases the resistance of the magnesium lining of industrial furnaces.
  • Olivine sand minimizes the introduction of additional raw fluxes into the converter charge in iron-ore magnesia pellets, and it reduces heat losses.
  • Olivine sand reduces the yield of converter slag by 2-3 times, compared with conventional acid iron-ore pellets.
  • Olivine sand makes the slag more liquid and active; it helps to remove alkali and improves the desulphurization process.
  • Olivine sand increases the solidity of iron-ore pellets.
  • Olivine sand is not subjected to decomposition reaction on which a sufficient amount of energy is spent in contrast to the raw metallurgical dolomite.
  • Olivine sand reduces the negative impact of bentonite clays in iron-ore magnesia pellets, so as the bentonite clays significantly increase the acidic environment and additionally add SiO2 and Na2O to pellets
  • Compared with quartz sands olivine has a low and uniform thermal expansion. This allows for more stable and controlled dimensional accuracy.


Olivine sands are widely used in the world practice in the manufacture of cast iron (gray, high solidity and malleable) and steels of all types, especially manganese. Due to its basic chemical nature, olivine does not interact with manganese unlike quartz sand. The main characteristics make olivine sand ideal for the production of austenitic manganese steels. Olivine sand is also used for facing molding mixtures in the manufacture of large steel and iron castings, which allows them to be obtained with a cleaner surface than using quartz sand. The special advantage of olivine sand is manifested in the production of heavy castings, when resistance to high ferrostatic pressure is required, due to the slow and linear nature of volumetric changes (in contrast to quartz sand, which has a structural transformation at 575 °C). Olivine has no allotropic transformations, resistant to slagging with iron oxides. The sintering temperature of 1450 °C, begins to fuse at temperatures above 1760 °C and the melting point between 1800 and 1850 °C.
