2019-1-1  However, since the 1970s, there has been a continuous depletion of high Fe grade ores, obliging the mineral companies to concentrate low Fe grade ores in order to reach the quality demand of the steel mills. It is estimated that 400 kg of tailings is produced for each tonne of beneficiated iron ore. This means there is a very big volume of tailings dumped from industrial plants over the years.

Geochemical Analysis or Iron Ore SGS

As many iron ores either are magnetite or contain magnetite, the use of Davis Tube Recovery (DTR) is industry standard for the quantitative analysis of the magnetic minerals in the sample. SGS experts will use DTR to determine the magnetic content of your iron ore. Sample material is placed in a glass tube at a 45° angle between 2 powerful electromagnets. A slurry sample is poured through the tube slowly and then the tube is rinsed with water so only a clean concentrate of magnetic material remains. Other geochemical analyses can then be used to further quantify the nonmagnetic content of the ore,
