iron ore processing techniques

When the iron ore is extracted from the mine, it must undergo several processing stages six steps to process iron ore screening we recommend that you begin by screening the iron ore to separate fine particles below the crushers css before the crushing stage a static screen is used to divert the fine particles for crushing
