phosphorous impurity in iron ore

Phosphorus is one of the most deleterious elements in iron ore as it follows iron during downstream reduction processes forming iron phosphides that make steel brittle Excess phosphorus increases the cost of steelmaking and the steel industry has placed an upper limit of 007–008 wt P on the iron ore ... As a leading global manufacturer of crushing equipment, milling equipment,dressing equipment,drying equipment and briquette equipment etc. we offer advanced, rational solutions for any size-reduction requirements, including quarry, aggregate, grinding production and complete plant plan.
