Iron ores can be classified in different ways. The most important has to do with the iron content. In many cases, ore with a total iron content of 60 to 63, or greater, is regarded as high grade, and ore with a lower iron content is regarded as low grade. Ores are also classified as follows, according to their size and the processing method.

Sep 25, 2018 Low grade Iron Ore Beneficiation and the Process of Jigging. Iron ore resources are getting consumed at an accelerated rate because of the growth in the production of iron and steel. Due to this reason the availability of high grade iron ore is reducing and the supply of high grade iron ore to iron and steel plants is declining sharply.
The low-grade clay-rich -1.0 mm fraction of fine iron ores have often proved difficult to upgrade and capital intensive to process when using traditional wet beneficiation technology including single or two stage hydrocyclone desliming, wet high intensity magnetic separation WHIMS, spirals and final dewatering using fine screens. Very fine 0.010 mm clay-rich slimes simply follow the water ...
