Iron

Iron ore is typically mined in huge volumes and only crushed and screened before it is exported. Nonetheless, certain deposits require physical processing of the ore to reach grades high enough to render transport economical. Our sorters can treat such ores in a dry process in size ranges of -300/+20mm and feed rates of up to 300t/h.

The sorter type utilized for iron ore upgrading depends on the mineralogical characteristics of the ore. Properties like atomic density and color are used.

X-ray transmission sorters are used to remove waste material from run-of-mine material and thereby upgrading the iron ore to acceptable levels. Optical sorters can separate certain iron ores from manganese ores where a density separation is impossible due to similar specific gravities and atomic densities.
