Iron Ore Processing - an overview ScienceDirect Topics

Current practice of washing iron ore before it is processed for extractive metallurgical operation results in three products, coarse ore lumps with sizes in the range 10-80 mm, which are directly charged to a blast furnace, the classifier fines of size 150 μm to 10 mm, which, with or without beneficiation are fed to sinter plants, and the tailings, below 150 μm in size, which are discarded as waste.

Iron ore - Wikipedia

For every 1 ton of iron ore concentrate produced approximately 2.5–3.0 tons of iron ore tailings will be discharged. Statistics show that there are 130 million tons of iron ore discharged every year. If, for example, the mine tailings contain an average of approximately 11% iron there would be approximately 1.41 million tons of iron wasted annually.
