The addition of iron ore concentration tailings to the ceramic mass increases its flexural strength, decreases the density, increases the porosity and decreases the water absorption, results which are very desirable to the ceramic industry. Further, these tailings are in the form of powder, thus requiring few or no grinding efforts, which is a ...
Iron ore is 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 (Fe 3 O 4) and hematite (Fe 2 O 3). Iron ore is the source of primary iron for the world's iron and steel industries.
