How to remove phosphorus from high phosphorus iron ore?
The leaching-precipitation method is suitable for the high phosphorus iron ore with phosphorus content more than 0.3%. The high phosphorus iron ore is leached with an acid solution to dissolve the phosphorus, and then the phosphorus is precipitated by adding a precipitant. The precipitated phosphorus can be recovered and utilized.
