iron concentrate from tailings

iron concentrate from tailings -

For every 1 ton of iron ore concentrate produced approximately 2.53.0 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.
