Jul 11, 2018· However, the content of iron ore in deposits has deteriorated and lowgrade iron ore has been processed. The fines resulting from the enrichment by separation after liberation by size reduction must be agglomerated in a pelletizing plant. Consequently, the number of pelletizing plants is expected to increase in the future.

Hematite in the iron ore was reduced to magnetite through magnetic roasting at 800 °C for 60 min, and iron was enriched through magnetic separation. However, an efficient separation between magnetite and quartz in the RRP800 °C was difficult to achieve because of the liberation issues, and the maximum Fe content in the concentrate only increased to 57.61%.

Iron ore is the key raw material for steel production enterprises. Generally, iron ore with a grade of less than 50% needs to be processed before smelting and utilization. After crushing, grinding, magnetic separation, flotation, and gravity separation, etc., iron is gradually selected from the natural iron ore.
