Iron Ore Inspection

Iron Ore Services

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 (Fe3O4) and hematite (Fe2O3).

Iron ore is the source of primary iron for the world’s iron and steel industries. It is therefore essential for the production of steel, which in turn is essential to maintain a strong industrial base.  Almost all (98%) iron ore is used in steelmaking.  Iron ore is mined in about 50 countries.   The seven largest of these producing countries account for about three-quarters of total world production.   Australia and Brazil together dominate the world’s iron ore exports, each having about one-third of total exports.


Send Your Iron Ore Sample

Contact Us Today

McCreath Laboratories will send trained, experienced technicians to take a represented sample for you.  Whether in bulk or containers, our technicians have the training, tools and experience to collect a representative sample, ensuring that all subsequent laboratory testing is accurate and reliable.  With our mobile crushing units, iron ore can be partially processed on site per the ISO and ASTM standards, increasing efficiency and reducing the amount of material taken off-site.

Iron Ore Experts at McCreath Labs

McCreath Laboratories will employ both classical and advanced in-house techniques in the analysis of iron ore.  The techniques have been verified through the use of certified reference materials and some are adopted directly from ASTM or ISO standards.  A typical ferrochrome analysis would be done as follows:
