Concentration
When the concentration of the ore is complete, it is time for pelletisation. Concentration means the beneficiation of finely ground ore by separation into a concentrate of iron ore powder with a very high level of purity. Flotation is a chemical process for particle separation.

Mining and Water Quality | U.S. Geological Survey
Mine drainage is metal-rich water formed from a chemical reaction between water and rocks containing sulfur-bearing minerals. The resulting chemicals in the water are sulfuric acid and dissolved iron. Some or all of this iron can come out as solids to form the red, orange, or yellow sediments in the bottom of streams containing mine drainage.

Ore concentrate
Ore concentrate, dressed ore or simply concentrate is the product generally produced by metal ore mines.The raw ore is usually ground finely in various comminution operations and gangue (waste) is removed, thus concentrating the metal component. The concentrate is then transported to various physical or chemical processes called hydrometallurgy, pyrometallurgy smelters, and electrometallurgy

Pollution From Mining
The water pollution is caused by acid that drains from the “Iron Mountain” mine, known as acid drainage. Acid drainage is serious stuff. With a pH value of 0, the groundwater near the “Iron Mountain” has been found to be 10,000 times more acidic than battery acid (this is VERY acidic). It’s the highest concentration of acid in the world.

Lower-grade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities. The results, high-quality fine ore powders, are known as fines. Magnetite. Magnetite is magnetic, and hence easily separated from the gangue minerals and

Vale adapts iron ore processing route to make sand product
The innovation introduced by Vale lies in the concentration stage where the by-product of the iron ore processing is once more processed until it reaches the necessary quality to become sand for commercial use. In the traditional method, this material would become tailings and be destined to dams or piles.
