The consumption of iron ore has increased rapidly over the past decade due to the tremendous growth of the iron and steel industry. The depletion of high-grade iron ore resources makes it inevitable to utilise the existing low-grade iron ores/fines/tailings with proper beneficiation to meet the present specification and demand.

Iron ore is an important raw material for steel production enterprises. In most cases, iron ore with a grade of less than 50% requires ore beneficiation before smelting and utilization. Natural ore (iron ore) is gradually selected for iron through procedures such as crushing, grinding, magnetic separation, flotation, and gravity separation.
