Mar 14, 2018 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 crushing.
Mar 14, 2018 A collector at the bottom of each spiral collects the heavy concentrate (so-called hematite concentrate) and eliminates the lighter unwanted particles (middlings and tails). This step is repeated two or three times, depending on the desired liberation and iron concentration. 6. Magnetic separation.
Concentration refers to the methods of producing ore fractions richer in iron and lower in silica than the original material. Most processes rely on density differences to separate light minerals from heavier ones, so the ore is crushed and ground to release the ore minerals from the gangue.
