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

The Noamundi iron ore beneficiation plant is the oldest iron ore beneficiation plant in India. A simple flow sheet consisting of crushing followed by screening and classification was used to beneficiate iron ore for many years. The main objective of beneficiation is here to reduce the alumina content in the concentrate.

What is iron ore beneficiation? 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 ...
