  • The Six Main Steps of Iron Ore Processing | Multotec Canada

    When the iron ore is extracted from the mine, it must undergo several processing stages Six steps to process iron ore 1 Screening We recommend that you begin by screening the iron ore to separate fine particles below the crusher’s CSS before the crushing stage A static screen is used to divert the fine particles for crushingMineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgyThe primary operations are comminution and concentration, but there are other important operationsMineral processing | metallurgy | Britannica
