ADVANCES IN MAGNETIC SEPARATION OF ORES

Dry Magnetic Separation of Iron Ore: There are many inherent advantages in processes that utilize dry magnetic separation to beneficiate iron ore. Wet concentration of magnetite ore, in comparison, re- quires 500 to 1000 gal of water per ton of concen- trate produced. This means extensive use of water resources, as well as disposal systems and some- times complicated water reclamation systems

The Six Main Steps of Iron Ore Processing Multotec Canada

14/03/2018 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 crushing. This step prevents overloading the crusher and increases its efficiency. Fine particles make the crusher less efficient and increase the power draft
