The six main steps of iron ore processing
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.

EVALUATION OF DRY COBBING -LTV
Coarse magnetic cobbing of the crushed ore has shown the advantages of rejecting a portion of low grade ore so that the energy consumption on the down stream grinding could be reduced. With the magnetic iron recovery to the concentrate at 98%, there is an optimum size, at minus 1-inch, which achieved the rejection of 14% by weight

Traceability in iron ore processing and transports
The ore is then fed to a cobbing plant, where the ore is crushed, screened and, since the ore is ferromagnetic magnetite, the majority of the gangue minerals can be separated through dry magnetic separation. The cobbing plant works continuously, and the batch-wise separation is thus lost in this step.
